| Abstract: | The production of benzyl acetate perfume with benzyl chloride and sodium acetate by phase transfer catalysis is presented. It can be confirmed that the technological process is simpler, and the by-reaction is less. The conversion is up to 99%, the selectivity is 98%-100% and the yield of product is 90%-95%. The optimum technological conditions producing benzyl acetate, and the recycling of excessive reactants and spent catalyst are investigated. This is an effective process to increase the output, to improve the quality, and to decrease the cost of production of benzyl acetate. |
