METHOD FOR THE PREPARATION OF A PURE ALKALI METAL BENZOATE BESIDES BENZYL ALCOHOL

摘要

ABSTRACTThe invention relates to a method for the preparation of apure alkali metal benzoate, specifically of a pure alkali metalbenzoate from benzyl benzoate prepared by oxidation of an alkyl benzenecompound, specifically toluene, with a gas containing molecularoxygen, besides benzyl alcohol, Very specifically the invention relatesto a method for the preparation of sodium benzoate besides benzylalcohol.For this purpose crude benzyl benzoate is subjected to a treatmentwith a reducing substance to convert impurities, under such circum-stance that, in the process, there will be no conversion of anysubstantial quantity of benzyl benzoate. Subsequently the benzylbenzoate is saponified to the alkali metal benzoate and benzyl alcohol.
