    1. Chemical Njirimara: Methyl benzoate dịtụ kwụsiri ike, ma ọ bụ hydrolyzed na-emepụta benzoic acid na methanol mgbe kpụ ọkụ n'ọnụ na ọnụnọ nke caustic alkali. Ọ dịghị mgbanwe ọ bụla mgbe a na-ekpo ọkụ na tube mechiri emechi na 380-400 ° C maka awa 8. Mgbe pyrolyzed na ntupu ígwè na-ekpo ọkụ, benzene, biphenyl, methyl phenyl benzoate, wdg na-etolite. Hydrogenation na 10MPa na 350°C na-emepụta toluene. Methyl benzoate na-enweta mmeghachi omume transesterification na mmanya ndị bụ isi na ọnụnọ alkali metal ethanolate. Dịka ọmụmaatụ, 94% nke mmeghachi omume na ethanol na ụlọ okpomọkụ na-aghọ ethyl benzoate; 84% nke mmeghachi omume na propanol na-aghọ propyl benzoate. Enweghị mmeghachi omume transesterification na isopropanol. Benzyl mmanya ester na ethylene glycol na-eji chloroform dị ka ihe mgbaze, na mgbe a na-agbakwunye obere potassium carbonate na reflux, ethylene glycol benzoate na obere ethylene glycol benzhydrol ester na-enweta. Methyl benzoate na glycerin na-eji pyridine mee ihe dị ka ihe mgbaze. Mgbe ikpo ọkụ na ọnụnọ sodium methoxide, a pụkwara ime transesterification iji nweta glycerin benzoate.
