Ester e entsoe ka esterization reaction ea inorganic acid kapa organic acid kapa joala.Joala kapa phenol kapa anhydride e nang le asiti, joala le ethylene, acidic e sa lefelloeng le lintho tse tsoang ho naetrojene e mafura le tsona li ka hlahisa ester.Hydrogen e holim'a alpha-carbon ka limolek'hule tsa ester e lahleheloa ke joala ea molek'hule ka ester e 'ngoe ea molek'hule tlas'a maemo a alkaline ho hlahisa β-keto ester, e bitsoang ester contraction reaction.Ka mohlala, acetyl acetate e hlahisoa ho hlahisa acetyl ethyl acetate.Karabelo ena e bohlokoa haholo ho organic synthesis.

Lebitso la ester le tsoa lebitsong le ts'oanang la carboxylic acid le joala kapa phenol, joalo ka "acid e itseng le ester e itseng".Li-ester tsa selikalikoe li bitsoa lactone (lactone).Lintho tsa lik'hemik'hale tsa ester li tšoana le amyl niche anhydride, e atisang ho ba le hydrolysis, joala le ammonia reaction.Ester ea boemo bo tlase ke mokelikeli o monko o monate ebile o fetoha o sa tsitsang, 'me ester e tsoetseng pele e tiile.Li-estes ke lihlapolli tsa bohlokoa le lisebelisoa tse tala tsa maiketsetso, 'me li-ester tse ling ke lithethefatsi ka botsona.Ho latela mofuta oa asiti, ester e ka aroloa ka inorganic acid ester le organic acid ester.Etate, ethyl acetate ke ester e mafura, acetate ke ester e nkhang hamonate, 'me namanonate ke ester ea cyclic.
