Ethyl and isobutyl acetates were pyrolyzed at various temperatures from 450 to 700°C, by which the variations of products with increase in the temperature were studied. The production increased in the amount with rise of the temperature, which tendency is common to the acetic esters carrying β-hydrogen, independently upon the number of β-hydrogen. The principal products from ethyl acetate were acetic acid, ethylene, acetone, carbon dioxide, methane and carbon monoxide. Those from isobutyl acetate were acetic acid, isobutylene, acetone, carbon dioxide, methane, carbon monoxide and a C5-compound. The production of acetic acid, ethylene and isobutylene increased with the rise of the temperature, whereas that of the other products mentioned above was almost temperature-independent. It may be attributed that the pyrolysis of ethyl acetate is an elimination reaction of ethylene, and that of isobutyl acetate is accompanied by other reactions in addition to an isobutylene elimination.
