Chemical properties Comparison of methyl benzoate Stable, but hydrolyzes to produce benzoic acid and methanol when heated in the presence of caustic alkali. There is no change when heated in a sealed tube at ~℃ for hours. When pyrolyzed on a hot metal mesh, benzene, biphenyl, phenyl methyl benzoate, etc. are produced. Hydrogenation produces toluene at ℃. Methyl benzoate undergoes transesterification reaction with primary alcohol in the presence of alkali metal ethanolates. For example, when reacting with ethanol at room temperature, it becomes ethyl benzoate. When reacting with propanol, it becomes propyl benzoate. Does not transesterify with isopropyl alcohol. Benzyl alcohol ester and ethylene glycol use chloroform as the solvent, and when a small amount of potassium carbonate is added and refluxed, ethylene glycol benzoate and a small amount of ethylene glycol diphenyl alcohol ester are obtained. When methyl benzoate and glycerin are heated with pyridine as a solvent in the presence of sodium methoxide, a transesterification reaction can also be carried out to obtain the benzoate ester of glycerol.
Methyl methanol is nitrated with nitric acid (relative density) at room temperature to obtain methyl nitrobenzoate and methyl nitrobenzoate in a ratio of Nitrile. Heated with phosphorus pentachloride to ~℃ to obtain benzoyl chloride.
Methyl formate forms a crystalline molecular compound with aluminum trichloride and tin chloride, and forms a flaky crystalline compound with phosphoric acid.
