Doesn't have enough hydrogen atoms for that. If it decomposes due to pressure and heat in a closed space, probably it turns into polycyclic aromatic hydrocarbon

Doesn't have enough hydrogen atoms for that. If it decomposes due to pressure and heat in a closed space, probably it turns into polycyclic aromatic hydrocarbons. Which incidentally is what a lot of interstellar dust is made from. Hmmm...
