    1. Chemical Properties: Methyl benzoate ne in mun gwada da barga, amma shi ne hydrolyzed don samar da benzoic acid da methanol lokacin da mai tsanani a gaban caustic alkali. Babu wani canji idan aka yi zafi a cikin bututun da aka rufe a 380-400 ° C na 8 hours. Lokacin da pyrolyzed a kan zafi karfe raga, benzene, biphenyl, methyl phenyl benzoate, da dai sauransu an kafa. Hydrogenation a 10MPa da 350 ° C yana haifar da toluene. Methyl benzoate yana jure wa halayen transesterification tare da barasa na farko a gaban alkali karfe ethanolate. Alal misali, 94% na amsawa tare da ethanol a dakin da zafin jiki ya zama ethyl benzoate; 84% na amsawa tare da propanol ya zama propyl benzoate. Babu amsawar transesterification tare da isopropanol. Benzyl barasa ester da ethylene glycol suna amfani da chloroform a matsayin sauran ƙarfi, kuma idan an ƙara ƙaramin adadin potassium carbonate zuwa reflux, ana samun ethylene glycol benzoate da ƙaramin adadin ethylene glycol benzhydrol ester. Methyl benzoate da glycerin suna amfani da pyridine azaman sauran ƙarfi. Lokacin da zafi a gaban sodium methoxide, transesterification kuma za a iya za'ayi don samun glycerin benzoate.

    2. Methyl benzyl barasa an nitrated tare da nitric acid (danganiyar density 1.517) a dakin da zafin jiki don samun methyl 3-nitrobenzoate da methyl 4-nitrobenzoate a cikin wani rabo na 2: 1. Yin amfani da thorium oxide a matsayin mai kara kuzari, yana amsawa da ammonia a 450-480 ° C don samar da benzonitrile. Yi zafi tare da pentachloride phosphorus zuwa 160-180 ° C don samun benzoyl chloride.

    3. Methyl benzoate ya samar da wani fili na kwayar halitta crystalline tare da aluminum trichloride da tin chloride, kuma ya samar da fili mai laushi tare da phosphoric acid.
