摘 要：乙酸芐酯是一種常用香料，經(jīng)多方面的比較與研究，本設(shè)計選用氯化芐和乙酸鈉在相轉(zhuǎn)移催化劑芐基三乙基氯化銨作用下酯化生成乙酸芐酯，該過程操作簡單，在溫和反應(yīng)體系中，催化劑及過剩反應(yīng)物乙酸鈉、水可循環(huán)使用，提高了效率, 降低了成本, 減少了污染。根據(jù)相關(guān)資料，一份年產(chǎn)5000噸乙酸芐酯生產(chǎn)車間的工藝設(shè)計說明書，主要包括物料衡算、能量衡算、釜體、車間布置等進行研究。根據(jù)工藝特點確定反應(yīng)周期為每批8小時，每天3批。通過物料衡算得到每一種所需原料的質(zhì)量；通過熱量衡算得到所需傳遞的熱量；然后根據(jù)衡算結(jié)果進行釜體設(shè)計,確定為8立方米的反應(yīng)釜，設(shè)計了釜體各部分尺寸,畫出生產(chǎn)工藝的反應(yīng)流程簡圖、車間布置圖和反應(yīng)釜體裝配圖。

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
