    Ohun elo

    1.It le ṣee lo bi epo fun awọn esters cellulose, awọn resin sintetiki ati awọn rubbers, ati awọn oluranlowo fun awọn okun polyester.

    2.O tun lo fun igbaradi ti awọn ounjẹ ounjẹ. O ti wa ni lo lati ṣe iru eso didun kan, ope oyinbo, ṣẹẹri, ọti ati awọn miiran lodi.

    Ohun ini

    O jẹ miscible pẹlu ether, methanol ati ether, ṣugbọn insoluble ninu omi ati glycerin.

    Ibi ipamọ

    Awọn iṣọra ibi ipamọ Itaja ni itura kan, ile-itaja afẹfẹ. Jeki kuro lati ina ati ooru orisun. Iwọn otutu ipamọ ko kọja 35 ℃, ati ọriniinitutu ojulumo ko kọja 85%. Jeki awọn eiyan ni wiwọ ni pipade. O yẹ ki o wa ni ipamọ lọtọ lati awọn oxidants, alkalis, ati awọn kemikali ti o jẹun, ki o si yago fun ibi ipamọ adalu. Ni ipese pẹlu orisirisi yẹ ati opoiye ti ina ẹrọ. Aaye ibi ipamọ yẹ ki o wa ni ipese pẹlu awọn ohun elo itọju pajawiri jijo ati awọn ohun elo ipamọ to dara.

    Iduroṣinṣin

    1. Awọn ohun-ini kemikali: Methyl benzoate jẹ iduroṣinṣin diẹ, ṣugbọn o jẹ hydrolyzed lati ṣe ina benzoic acid ati kẹmika nigba ti o gbona ni iwaju alkali caustic. Ko si iyipada nigbati o ba gbona ni tube ti a fi edidi ni 380-400 ° C fun wakati 8. Nigbati pyrolyzed lori apapo irin ti o gbona, benzene, biphenyl, methyl phenyl benzoate, ati bẹbẹ lọ ni a ṣẹda. Hydrogenation ni 10MPa ati 350°C ṣe ipilẹṣẹ toluene. Methyl benzoate faragba a transesterification lenu pẹlu jc alcohols ni niwaju alkali irin ethanolate. Fun apẹẹrẹ, 94% ti iṣesi pẹlu ethanol ni iwọn otutu yara di ethyl benzoate; 84% ti iṣesi pẹlu propanol di propyl benzoate. Ko si ifaseyin transesterification pẹlu isopropanol. Benzyl oti ester ati ethylene glycol lo chloroform bi epo, ati nigbati iye kekere ti potasiomu carbonate ti wa ni afikun si reflux, ethylene glycol benzoate ati iye kekere ti ethylene glycol benzhydrol ester ni a gba. Methyl benzoate ati glycerin lo pyridine bi epo. Nigbati o ba gbona ni iwaju iṣuu soda methoxide, transesterification tun le ṣee ṣe lati gba glycerin benzoate.

    2. Methyl benzyl oti jẹ iyọ pẹlu nitric acid (iwuwo ibatan 1.517) ni iwọn otutu yara lati gba methyl 3-nitrobenzoate ati methyl 4-nitrobenzoate ni ipin ti 2: 1. Lilo oxide thorium bi ayase, o ṣe pẹlu amonia ni 450-480°C lati gbe awọn benzonitrile jade. Ooru pẹlu irawọ owurọ pentachloride si 160-180 °C lati gba benzoyl kiloraidi.

    3. Methyl benzoate ṣe fọọmu molikula molikula kan pẹlu aluminiomu trichloride ati tin chloride, ati pe o jẹ agbo-ara ti o ni flaky pẹlu phosphoric acid.
