摘 要：乙酸苄酯是一种常用香料，经多方面的比较与研究，本设计选用氯化苄和乙酸钠在相转移催化剂苄基三乙基氯化铵作用下酯化生成乙酸苄酯，该过程操作简单，在温和反应体系中，催化剂及过剩反应物乙酸钠、水可循环使用，提高了效率, 降低了成本, 减少了污染。根据相关资料，一份年产5000吨乙酸苄酯生产车间的工艺设计说明书，主要包括物料衡算、能量衡算、釜体、车间布置等进行研究。根据工艺特点确定反应周期为每批8小时，每天3批。通过物料衡算得到每一种所需原料的质量；通过热量衡算得到所需传递的热量；然后根据衡算结果进行釜体设计,确定为8立方米的反应釜，设计了釜体各部分尺寸,画出生产工艺的反应流程简图、车间布置图和反应釜体装配图。

Abstract:The benzyl acetate is one kind of commonly used spice, This design selects the chlorination animal pen and the sodium acetate in shifts under the catalyst phenmethyl triethyl ammonium chloride function the esterification production benzyl acetate. This process operation is simple, in the temperate reacting system, the catalyst and the surplus reactant sodium acetate, the water may circulate the use, enhanced the efficiency, reduced the cost, reduced the pollution. According to a experimental technical document, a yearly products of 5000 tons of tolclofos-methyl is designed. The design mainly includes the material balance, the energy balance, body, the workshop decoration etc.According to the the process characteristics, we definite the reaction cycle for 8 hours each time, everyday 3pass. According to the results of balance, We design the kettle ,also definite a Reactor of  8 cubic meters, though Mass Balance, quality that materials needed each time, and though Heat Balance, calories that needed to deliver, the design also included the body each parts of sizes,  the production craft the response flow diagram, the workshop general arrangement and the response cauldron body are given.

Keywords:benzyl acetate;mass balance;heat balance;kettle design;workshop layout
