    1. Hiki ke hoʻohana ʻia e like me ka solvent no cellulose esters, synthetic resins a me rubbers, a me nā mea kōkua no nā fiber polyester.

    Hoʻohana ʻia ʻo 2.It no ka hoʻomākaukau ʻana i nā ʻono meaʻai. Hoʻohana ʻia ia e hana i ka strawberry, pineapple, cherry, rum a me nā mea ʻē aʻe.

    Waiwai

    Hiki ke hoʻopili ʻia me ka etera, ka methanol a me ka etera, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka glycerin.

    E mālama i ka mālama ʻana E kūʻai i loko o kahi hale kūʻai anuanu. E mālama i ke ahi a me nā kumu wela. ʻAʻole ʻoi aku ka mahana o ka mālama ʻana ma mua o 35 ℃, a ʻaʻole ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o 85%. Paʻa paʻa ka ipu. Pono e mālama ʻokoʻa ʻia mai nā oxidants, alkalis, a me nā kemika hiki ke ʻai, a pale i ka waiho ʻana. Hoʻolako ʻia me ka ʻano kūpono a me ka nui o nā lako ahi. Pono e hoʻolako ʻia ka wahi mālama me nā lako lapaʻau ulia pōpilikia a me nā mea mālama pono.

    1. Nā waiwai kemika: Methyl benzoate ua paʻa, akā, ua hydrolyzed ia e hoʻohua ai i ka waikawa benzoic a me ka methanol ke hoʻomehana ʻia i ke alo o ka caustic alkali. ʻAʻohe hoʻololi i ka wā e wela ai i loko o kahi paipa i hoʻopaʻa ʻia ma 380-400 ° C no 8 mau hola. Ke hoʻopili ʻia ma luna o ka metala wela, hoʻokumu ʻia ka benzene, biphenyl, methyl phenyl benzoate, etc. ʻO ka hydrogenation ma 10MPa a me 350 ° C e hoʻohua i ka toluene. Loaʻa ka methyl benzoate i kahi pane transesterification me nā waiʻona mua ma ke alo o ka ethanolate metala alkali. No ka laʻana, 94% o ka hopena me ka ethanol ma ka lumi wela e lilo i ethyl benzoate; 84% o ka hopena me ka propanol e lilo i propyl benzoate. ʻAʻohe hopena transesterification me ka isopropanol. Hoʻohana ka Benzyl alcohol ester a me ka ethylene glycol i ka chloroform ma ke ʻano he mea hoʻoheheʻe, a ke hoʻohui ʻia kahi wahi liʻiliʻi o ka potassium carbonate i reflux, e loaʻa ka ethylene glycol benzoate a me kahi mea liʻiliʻi o ka ethylene glycol benzhydrol ester. Hoʻohana ka Methyl benzoate a me ka glycerin i ka pyridine ma ke ʻano he mea hoʻoheheʻe. Ke hoʻomehana ʻia i mua o ka sodium methoxide, hiki ke hana ʻia ka transesterification e loaʻa ai ka glycerin benzoate.

    2. Hoʻopiʻi ʻia ka waiʻona methyl benzyl me ka waikawa nitric (pili 1.517) i ka mahana lumi e loaʻa ai ka methyl 3-nitrobenzoate a me ka methyl 4-nitrobenzoate ma ka ratio o 2:1. Ke hoʻohana nei i ka thorium oxide ma ke ʻano he catalyst, hana ia me ka amonia ma 450-480 ° C e hana i ka benzonitrile. E wela me ka phosphorus pentachloride i 160-180°C e loaʻa ai ka benzoyl chloride.

    3. Hoʻokumu ʻia ka Methyl benzoate i ka hui molekika crystalline me ka alumini trichloride a me ka tin chloride, a hana i kahi hui crystalline flaky me ka phosphoric acid.
