| titleOfInvention | A kind of production technology of benzyl alcohol |
| abstract | The invention relates to the technical field of perfume processing, in particular to a production process of benzyl alcohol. The process comprises the following operation steps: esterification reaction: adding benzyl chloride and a phase transfer catalyst raw material liquid into a sodium acetate solution, and performing an esterification reaction to obtain a first One crude ester; one time washing: washing the first crude ester with water to obtain the first brine and the second crude ester; two washings: washing the second crude ester with water again to obtain the second brine and the third crude ester; rectification under reduced pressure: The third crude ester is distilled under reduced pressure, and the fraction is condensed to obtain the finished product benzyl acetate; hydrolysis reaction: the above-mentioned benzyl acetate is hydrolyzed under alkaline conditions to obtain benzyl alcohol; Mass production. |
