Ignition: An Informal History of Liquid Rocket Propellants (1972) [pdf]
- sonofgod 6y agoAn absolute classic: people may not be aware it got reprinted, and is therefore available in dead-tree (and ebook) format again.
- Anneliese777 6y agoThere is also an audio-book. I enjoyed the narrator's take on it, his occasional dead-pan reading of something ridiculous reduced me to giggles. https://www.audible.com/pd/Ignition-Audiobook/B07CTTXLL6 https://www.audible.com/pd/Ignition-Audiobook/B07CTTXLL6
- sonofgod 6y agoOn chlorine trifluoride: ”It is, of course, extremely toxic, but that’s the least of the problem. It is hypergolic with every known fuel, and so rapidly hypergolic that no ignition delay has ever been measured. It is also hypergolic with such things as cloth, wood, and test engineers, not to mention asbestos, sand, and water-with which it reacts explosively. It can be kept in some of the ordinary structural metals-steel, copper, aluminium, etc.-because of the formation of a thin film of insoluble metal fluoride which protects the bulk of the metal, just as the invisible coat of oxide on aluminium keeps it from burning up in the atmosphere. If, however, this coat is melted or scrubbed off, and has no chance to reform, the operator is confronted with the problem of coping with a metal-fluorine fire. For dealing with this situation, I have always recommended a good pair of running shoes.” (via https://blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time https://blogs.sciencemag.org/pipeline/archives/2008/02/26/sa...)

- Sharlin 6y agoI never fail to upvote this quote.
- erik_seaberg 6y agoI've read every Things I Won't Work With and I wish Lowe would write more; he's the Dave Barry of chemistry.
- jowiar 6y agoI spent years following Lowe for the Things he Won't Work With, but somewhere a few weeks ago I was made aware of his coverage of COVID drug development, which has been phenomenal (and is what he actually does work with).
- cstross 6y agoBut ClF3 is harmless compared to dimethyl mercury (which he also goes into) -- and which the USAF contemplated as a reaction mass for air to air missiles, until they realized the mercury in the exhaust plume would melt their launch aircraft wings (not to mention being a potent neurotoxin), at which point they tried to sell it to the US Navy!
- Ididntdothis 6y agoIt seems this book is best if you read some small excerpts. I tried to read the whole book but I found the author to be a little too full of himself to make the book enjoyable.
- masklinn 6y agoI guess that's an YMMV thing, I had no issue reading Ignition! and very much enjoyed the trip.
- Ididntdothis 6y agoVery true. Sometimes I hate a book but when I read it again later It’s suddenly enjoyable. Maybe I was just in a bad mood when I read Ignition.
- FlyMoreRockets 6y agoSame here. The day I discovered it in the engineering library, I sat down in the stack and read it cover to cover. Very difficult to put down.
- gww 6y agoI really struggled with this book too. I am fascinated by the research behind space travel but I find some of the books really hard to enjoy. Another one I have struggled with is Sunburst and Luminary, I may not have the technical background to appreciate it.
- Karunamon 6y agoBoth of you may wish to give the audiobook a try. I had the same problem with the font being nigh-unreadble. I found the narration in the audio version to be very nice.
- gww 6y agoThat's a great idea thanks. I am spending so much time in the car right now because of COVID and I have run out of podcasts.
- hoorayimhelping 6y agoFor context, this book was out of print for a long time and the only way to get it was via PDF. The recent re-interest in rockets has led to it being re-published. https://smile.amazon.com/Ignition-Informal-Propellants-University-Classics/dp/0813595835/ https://smile.amazon.com/Ignition-Informal-Propellants-Unive...
- FlyMoreRockets 6y agoBefore it was reprinted, a buddy was going through hard times and to help him out, I bought his hard hard-cover, near mint copy for the going rate at the time: $500.
- exmadscientist 6y agoI found the reprint extremely difficult to read due to poor layout decisions. In particular, the font they used for subscripts (the 3 in ClF₃) is tiny and illegible. And there are rather a lot of those in a chemistry book.... I don't think anyone proofed it.
- ravedave5 6y agoSuch a great book.
- jabl 6y agoThis is a classic. Although it's a subject with absolutely no relevance to the vast majority of readers, it's written in a funny dry style (for a good example, see e.g. the quote posted in another comment). It's also interesting to reflect on rocket fuels since the publication of the book. - Military rockets have mostly shifted from hypergolics to solid fuels. - Orbital rockets mostly use LOX + suitable fuel. For the fuel, seems to be good arguments for and against everything from hydrogen to heavier hydrocarbons like kerosene. - Exotics (flourine, boron, etc.) have disappeared. - For hypergolics, the remaining use is mostly RCS's, deep space stuff, but not "main" propulsion. And the oxidizer is mostly NTO rather than acid that seemed to be Clark's favorite.
- Symmetry 6y agoIndia and China still make use of hypergolics for their main launch vehicles, though both are moving away from that.
- jkachmar 6y agoRegarding hypergols, I love the fact that you are absolutely correct that they’re mostly relegated to places where you _need_ autoignition these days, but then you look at the Proton rocket family... https://en.wikipedia.org/wiki/Proton_(rocket_family) https://en.wikipedia.org/wiki/Proton_(rocket_family)
- catalogia 6y agoIf it ain't broke, don't fix it. Titan IIs are no longer around, but they too were used into the 21st century.
- jabl 6y agoNot broken, but better choices are available. Many early space rockets were outgrowths of military ballistic missile programs, where hypergolics were favoured due to storability, as being able to launch on a moment's notice was critical. But for launching satellites or humans into orbit, that's not a particularly relevant consideration. On the downside, hypergolics are expensive, and their toxicity makes handling them more expensive still. Meanwhile, cryogenic technology has developed and is today affordable and reliable. Heck, even amateur efforts like Copenhagen Suborbitals are using LOX.
- lighttower 6y agoI read the book cover to cover after finding references to it by Derek Lowe on his pipeline blog [1]. Learned a lot about chemistry and the enormous investment that went into the space age (mostly because of overlapping technology for ICBMs and other rocket powered weapons) which is daunting as this book ONLY covers what's been declassified as of the 80s in propelants.

- steffan 6y agoIf you liked Ignition you may also like Eric Schlosser's Command and Control. I thought it was well written and enjoyed his style of weaving the story throughout the book.
- hprotagonist 6y agoIf you like this (and you should), I also recommend: Gergel, M. G. (1979). Excuse me sir, would you like to buy a kilo of isopropyl bromide?

We had never had such a dreadful assignment. Anyone working with this “superstink” is branded and given a wide berth. No matter how amorous his spouse may be, passion crumples despite baths, Chlorox and Dentine. For a while we made isovaleroyl chloride at Cedar Terrace. It created pandemonium among residents who first sniffed each other, came to the plant to sniff us, and then sniffled to their lawyers.

- tectonic 6y agoThis book is way more entertaining than one would expect of a book from 1972 about rocket propellants. It's now back in print, probably because Musk called it "fun". In addition to the infamous section about chlorine trifluoride and running shoes, I learned a lot about hydrogen peroxide as an oxidizer and monopropellant, as well as enjoyed a section on nuclear rockets. If you're into this sort of nerdery, you might enjoy The Orbital Index, my weekly newsletter about the space industry. https://orbitalindex.com https://orbitalindex.com

- ChrisMarshallNY 6y agoAwesome book! I have this (in digital form). Derek Lowe mentions it in one of my favorite In the Pipeline articles: https://blogs.sciencemag.org/pipeline/archives/2008/02/26/sand_wont_save_you_this_time https://blogs.sciencemag.org/pipeline/archives/2008/02/26/sa...
- sciencemadness 6y agoIt's always a pleasure to see Sciencemadness linked here. The link is usually to this book, and with good reason. It's a classic. You don't have to be a chemist to enjoy it (though that helps). I have a main account here but I never comment on Sciencemadness submissions through it because the site so easily reveals my real-life identity. I first discovered Ignition! on the shelves of the Medford, Oregon public library when I was 10 years old. I was hooked on my first reading and would go on to read it several more times before I entered my teens. It was tied with Tenney L. Davis's The Chemistry of Powder and Explosives as my favorite non-fiction book. I started the Sciencemadness library [1] a long time ago, before the big book-scanning initiatives like Google Books started. The library still contains a large number of books that are unremarkable except for the fact that they were among the first digitized books covering certain facets of chemistry to be made available online. The library does contain a couple of books less famous than Ignition! but also potentially interesting to non-chemist readers: Excuse Me Sir, Would You Like to Buy a Kilo of Isopropyl Bromide? This is an anecdotal, autobiographical sketch of Max Gergel and his adventures as a young (then older) mad scientist building the business Columbia Organic Chemicals. Columbia Organic Chemicals and its founder, Max Gergel, had the unusual honor of mention and praise by name in Kary Mullis's Nobel lecture [2]: "I never tired of tinkering in labs. During the summer breaks from Georgia Tech, Al Montgomery and I built an organic synthesis lab in an old chicken house on the edge of town where we made research chemicals to sell. Most of them were noxious or either explosive. No one else wanted to make them, somebody wanted them, and so their production became our domain. We suffered no boredom and no boss. We made enough money to buy new equipment. Max Gergel, who ran Columbia Organic Chemicals Company, and who was an unusually nice man, encouraged us and bought most of our products, which he resold. There were no government regulators to stifle our fledgling efforts, and it was a golden age, but we didn't notice it. We learned a lot of organic chemistry." The chicken coop lab full of noxious chemicals isn't far removed from how Max Gergel got his start in the chemistry business either. In this humorous, anecdotal chronicle of Max's life from high school mad scientist to successful operator of a chemical supply business, you'll learn where metallic potassium should NOT be stored, how to prepare perfectly alcohol-free n-dodecyl bromide, and why one man would be crazy enough to want a preparative scale procedure for methyl isocyanide. You'll also learn, humorously but quite clearly, how the golden age of "no government regulators" contained the seeds of its own destruction, as horrendous odors, accidental poisonings, dumpings, fires, and miscellaneous accidents and occupational hazards take their toll on Gergel and his employees, neighbors, and surrounding environs. http://library.sciencemadness.org/library/books/gergel_isopropyl_bromide.pdf http://library.sciencemadness.org/library/books/gergel_isopr... The Scientific Method: A Personal Account of Unusual Projects in War and in Peace Famed Harvard chemistry professor Louis Fieser's personal history of development of incendiary weapons during WW II, including the infamous Bat Bomb, plus development of cortisone, antimalarial drugs, and educational material for students. Louis Fieser joined the American war effort before America had even officially entered World War II, as one of 20 professor invited to the house of Roger Adams in October 1940 to join the National Defense Research Committee. He was instructed early on to work on chemical vesicants but, considering them inhumane, quickly made a lateral move to begin development of gelled gasoline incendiary weapons. He led the research effort behind napalm, several other components of large-scale incendiary ordnance, and smaller special purpose incendiary devices for use by spies and saboteurs. Fieser's strangest project was development of the Bat Bomb: a cluster-bomb arrangement of hibernating bats carrying time-delayed incendiaries. As the bats fell from bombers over enemy cities, they would rouse from hibernation mid-air and seek shelter in attics of the city below. Their incendiaries would then start concealed, hard-to-fight fires. The project was surprisingly successful for one never deployed, and included the own-goal immolation of an administrative building during testing. When Fieser was not working on setting fires he also had time to begin work on the first edition of his organic chemistry textbook, research cortisone chemistry, and work on antimalarial drugs. The information given late in the book about getting cats to pose for photographs with chemical apparatus is invaluable because it comes from real experience. http://library.sciencemadness.org/library/books/the_scientific_method.pdf http://library.sciencemadness.org/library/books/the_scientif...

- cclark00 6y agoThe most jaw dropping but easily missed story I remember from that book: "That was the case once, when we were all seated around the table in the middle of the lab, having lunch. I glanced up, and noticed that the contents of one flask was turning a little brown. "Who owns that one?" [...they hit the deck as it exploded] Who eats lunch in a chemistry lab?
