Njirimara ngwaahịa:
1.Gradually hydrolysed n'ihu mmiri na-emepụta acetic acid na propanol. Ọsọ hydrolysis bụ 1/4 nke ethyl acetate. Mgbe propyl acetate na-ekpo ọkụ na 450 ~ 470 ℃, na mgbakwunye na ịmepụta propylene na acetic acid, e nwere acetaldehyde, propionaldehyde, methanol, ethanol, ethane, ethylene na mmiri. Na ọnụnọ nke nickel catalyst, kpụ ọkụ n'ọnụ ruo 375 ~ 425 ℃, ọgbọ nke carbon monoxide, carbon dioxide, hydrogen, methane na ethane. Chlorine, bromine, hydrogen bromide na propyl acetate na-emeghachi omume na obere okpomọkụ. Mgbe emere ya na chlorine n'okpuru ọkụ, a na-emepụta 85% nke monochloropropyl acetate n'ime awa 2. N'ime nke a, 2/3 bụ ihe nnọchi 2-chloro yana 1/3 bụ ihe nnọchi 3-chloro. N'ebe aluminom trichloride nọ, propyl acetate na-ekpo ọkụ na benzene iji mepụta propylbenzene, 4-propylacetophenone na isopropylbenzene.
