    Ha e kopane le ether, methanol le ether, empa ha e kopane le metsi le glycerin.

    Polokelo

    Litlhokomelo tsa polokelo Boloka sebakeng sa polokelo se pholileng se nang le moea o pholileng. Qoba hole le mehloli ea mollo le mocheso. Thempereichara ea polokelo ha e fete 35 ℃, 'me mongobo o lekanyelitsoeng ha o fete 85%. Boloka setshelo se koetsoe ka thata. E lokela ho bolokoa ka thoko ho li-oxidants, alkalis, le lik'hemik'hale tse jeoang, 'me u qobe polokelo e tsoakiloeng. Ho hlomelloa ka mefuta e fapaneng e loketseng le bongata ba lisebelisoa tsa mollo. Sebaka sa polokelo se lokela ho ba le lisebelisoa tsa phekolo ea tšohanyetso tse lutlang le lisebelisoa tse loketseng tsa polokelo.

    Botsitso

    1. Lintho tsa lik'hemik'hale: Methyl benzoate e batla e tsitsitse, empa e hydrolyzed ho hlahisa benzoic acid le methanol ha e futhumala ka pel'a caustic alkali. Ha ho na phetoho ha e futhumatsoa ka har'a tube e tiisitsoeng ka 380-400 ° C bakeng sa lihora tse 8. Ha pyrolyzed holim'a letlooeng la tšepe e chesang, benzene, biphenyl, methyl phenyl benzoate, joalo-joalo. Hydrogenation ho 10MPa le 350°C e hlahisa toluene. Methyl benzoate e kena karabelong ea transesterification le lino tse tahang tsa mantlha boteng ba alkali metal ethanolate. Ka mohlala, 94% ea karabelo le ethanol mocheso oa kamore e fetoha ethyl benzoate; 84% ea karabelo e nang le propanol e fetoha propyl benzoate. Ha ho na karabelo ea transesterification ka isopropanol. Benzyl alcohol ester le ethylene glycol li sebelisa chloroform e le solvent, 'me ha palo e nyenyane ea potassium carbonate e kenngoa ho reflux, ethylene glycol benzoate le palo e nyenyane ea ethylene glycol benzhydrol ester e fumanoa. Methyl benzoate le glycerin li sebelisa pyridine e le solvent. Ha mocheso ka pel'a sodium methoxide, transesterification e ka boela ea etsoa ho fumana glycerin benzoate.

    2. Methyl benzyl alcohol e na le nitric acid (relative density 1.517) mocheso oa kamore ho fumana methyl 3-nitrobenzoate le methyl 4-nitrobenzoate ka karolelano ea 2: 1. Ka ho sebelisa thorium oxide e le mokelikeli, e sebetsana le ammonia ho 450-480 ° C ho hlahisa benzonitrile. Chesa ka phosphorus pentachloride ho 160-180°C ho fumana benzoyl chloride.

    3. Methyl benzoate e etsa motsoako oa crystalline molecular e nang le aluminium trichloride le tin chloride, 'me e etsa motsoako oa crystalline o nang le phosphoric acid.
