1.Chemical Properties: Butanone dị mfe na mmeghachi omume dịgasị iche iche n'ihi otu carbonyl ya na hydrogen na-arụ ọrụ n'akụkụ otu carbonyl. Condensation na-eme mgbe ejiri hydrochloric acid ma ọ bụ sodium hydroxide kpoo ọkụ iji mepụta 3,4-dimethyl-3-hexen-2-one ma ọ bụ 3-methyl-3-hepten-5-one. Mgbe ekpughere ìhè anyanwụ ruo ogologo oge, a na-emepụta ethane, acetic acid na ngwaahịa condensation. Mgbe oxidized na nitric acid, biacetyl na-etolite. Mgbe oxidized na chromic acid na ndị ọzọ siri ike oxidants, acetic acid na-emepụta. Butanone kwụsiri ike na ikpo ọkụ, karịa 500°CThermal cracking iji mepụta alkenone ma ọ bụ methyl alkenone. Mgbe a na-ejikọta ya na aliphatic ma ọ bụ aromatic aldehydes, ọ na-emepụta ketones dị arọ dị elu, ogige cyclic, ketones na resins, wdg. Dịka ọmụmaatụ, mgbe ejiri formaldehyde na-ejikọta ya na ọnụnọ sodium hydroxide, ọ na-emepụta bi-acetyl. Dịka ọmụmaatụ, condensation na formaldehyde na ọnụnọ sodium hydroxide na-ebu ụzọ mepụta 2-methyl-1-butanol-3-otu wee dehydrates iji mepụta ketone methylisopropenyl. Ngwakọta a na-enweta resination mgbe ekpughere ya na ìhè anyanwụ ma ọ bụ ìhè ultraviolet. Condensation na phenol na-emepụta 2,2-bis (4-hydroxyphenyl) butane. Na-emeghachi omume na esters aliphatic n'ihu ihe na-eme ka ọ bụrụ β-diketones. Acylation na anhydride na ọnụnọ nke ihe na-eme ka acidic mepụta β-diketone. Mmeghachi omume na hydrogen cyanide iji mepụta cyanohydrin. Ọ na-emeghachi omume na amonia iji mepụta ketopiperidine mwepu. A na-eji halogen dochie α-hydrogen atọm nke butanone ngwa ngwa iji mepụta ketones dị iche iche, dịka 3-chloro-2-butanone nwere chlorine. Mmekọrịta na 2,4-dinitrophenylhydrazine na-emepụta odo 2,4-dinitrophenylhydrazone (mp 115 ° C).
