PREPARATION OF BENZYL ACETATE BY MEANS OF PHASE TRANSFER CATALYSIS |
| |
| Abstract: | This paper describes a new method for preparation of benzyl acetate by means of es-terification of sodium acetate trihydrate with benzyl chloride in the presence of quaternary ammonium salt Q-l as phase transfer catalyst. Under the condition of mole ration NaAc·222223H2O : PhCH2Cl: Q-l = l. 25 : 1 : 0. 05, the yield of the esterification for 2 hours at boiling is 89%, the purity of benzyl acetate is over 99%. The phase transfer catalyst Q-l can be repeatedly used. |
