    Application

    1.Inogona kushandiswa se solvent ye cellulose esters, synthetic resins uye rubbers, uye zvinobatsira zvepolyester fibers.

    2.Iyo inoshandiswawo pakugadzirwa kwezvokudya zvinonaka. Inoshandiswa kugadzira sitirobheri, chinanazi, cherry, rum uye zvimwe zvakakosha.

    Property

    Inosanganiswa ne ether, methanol uye ether, asi isinganyunguriki mumvura uye glycerin.

    Storage

    Chengetedzo munzvimbo inotonhorera, ine mhepo yekuchengetera mhepo. Ramba kure nemoto nekupisa. Tembiricha yekuchengetera haipfuure 35 ℃, uye hunyoro husingapfuuri 85%. Chengetedza mudziyo wakavharwa zvakasimba. Inofanirwa kuchengetwa zvakasiyana kubva kune oxidants, alkalis, uye makemikari anodyika, uye kudzivirira kusanganiswa kuchengetedza. Yakashongedzerwa nemhando yakakodzera uye huwandu hwemidziyo yemoto. Imba yekuchengetera inofanirwa kuve neyakavharika yekukurumidzira kurapwa michina uye yakakodzera yekuchengetedza zvinhu.

    Kugadzikana

    1. Chemical properties: Methyl benzoate haina kugadzikana, asi inogadzirwa nehydrolyzed kuti igadzire benzoic acid uye methanol kana ichipisa pamberi pe caustic alkali. Iko hakuna shanduko kana inopisa muchubhu yakavharwa pa 380-400 ° C kwemaawa masere. Kana yaiswa pyrolyze pameshi yesimbi inopisa, benzene, biphenyl, methyl phenyl benzoate, zvichingodaro. Hydrogenation pa10MPa uye 350°C inogadzira toluene. Methyl benzoate inosangana netransesterification reaction nemadoro ekutanga pamberi pealkali metal ethanolate. Somuenzaniso, 94% yezvinoitwa ne ethanol pamhepo yekushisa inova ethyl benzoate; 84% yezvinoitwa nepropanol inova propyl benzoate. Iko hakuna transesterification reaction ne isopropanol. Benzyl alcohol ester uye ethylene glycol inoshandisa chloroform se solvent, uye kana zvishoma zve potassium carbonate yakawedzerwa kune reflux, ethylene glycol benzoate uye zvishoma zve ethylene glycol benzhydrol ester inowanikwa. Methyl benzoate uye glycerin vanoshandisa pyridine sechinhu chinonyungudutsa. Kana inopisa pamberi pe sodium methoxide, transesterification inogonawo kuitwa kuti iwane glycerin benzoate.

    2. Methyl benzyl alcohol is nitrated ne nitric acid (relative density 1.517) panzvimbo yekushisa kuti iwane methyl 3-nitrobenzoate uye methyl 4-nitrobenzoate muchiyero che2: 1. Ichishandisa thorium oxide sechinhu chinokonzera, inopindirana neammonia pa450-480 ° C kugadzira benzonitrile. Pisa nephosphorus pentachloride kusvika 160-180°C kuti uwane benzoyl chloride.

    3. Methyl benzoate inoumba crystalline molecular compound ine aluminum trichloride netin chloride, uye inoumba musanganiswa wecrystalline wakatsetseka une phosphoric acid.

    4. Kugadzikana uye kugadzikana

    5. Zvinhu zvisingaenderani, oxidants yakasimba, alkali yakasimba

    6. Polymerization njodzi, hapana polymerization
