Chemical reactions are divided into two types of thermal reaction and catalytic reactions. Thermal reaction: hydrocarbons at about 450 ℃ start that significant thermal reactions (including cracking and condensation). Under heating conditions, mainly carbon alkane chain scission sales n-propyl acetate, generates fewer carbon number alkanes and alkenes; cycloalkanes mainly strand breaks and naphthenic ring side cracking reaction; aromatic hydrocarbons in addition to the outer side of chain scission occurs further condensation reaction of polycyclic aromatic hydrocarbons until coke (see) n-propyl acetate, aromatic ring itself is difficult to crack. The material world is colorful, from the most primitive ancient classification (gold, wood, water, fire and earth) to modern (as of December 12, 2013) There are hundreds of thousands of compounds to determine the composition, and each year there are a large number of The new compounds were found. The number of known compounds, n-propyl acetate purposes, various aspects of the statistics is not consistent. More generally accepted in the United States, "Chemical Abstracts" the editorial department statistics: artificial compounds and synthetic compounds have been found to naturally occurring, about more than three million kinds. Some of these compounds consisting of two elements, by some three, four or even more of the chemical elements. Each year there are still number of newly synthesized compounds of more than 30 million, of which 90% are organic compounds.
