 摘 要：山梨酸又称花楸素，是高效安全且毒性最低的新型食品防腐剂。本文对山梨酸的几种合成方法进行了一定地分析和比较， 并最终确定用有机电化学合成山梨酸法，作为本次设计的工艺路线。该方法在常压下进行，物耗、能耗较低，原料易得，毒性小，产品纯度较高，收率较高。此外，此工艺产生的三废少，有利于实现大规模连续生产。本文查阅了相关文献资料，对年产600吨山梨酸进行了生产工艺设计，主要包括物料衡算、热量衡算、反应釜釜体设计和车间布置等部分。根据工艺特点，确定反应周期为每批24小时，每天1批；由物料衡算，算得每种所需原料的质量；由热量衡算，算得所需传递的热量和传热面积；然后根据衡算结果进行釜体设计，确定采用2立方米的反应釜，在此基础上，对釜体的各个部分进行设计和选型，并给出了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: Sorbic acid, known as Su Sorbus, is an safe and effective new food preservative which have the lowest tocicity. In this paper , we compare and analyze several synthetic methods and finally, we determine to use the method of organic electrochemical synthesis to obtain sorbic acid. This method carries on under normal pressure. Due to low material consumption, low energy consumption, raw materials readily available, low toxicity, high purity and high yield, In addition, less waste generated by this process ,it is conducive to large-scale continuous production. According to the correlation data, this article designed one way to produce 600 ton sorbic acid a year. It include material republican, calories republican, reactor design , plant layout and other parts. According to the technical characteristics, determining for each batch of 24-hour period , a batch  each day. The quality of raw materials is determined by material balance, and the necessary heat transfer and area is determined by heat balance. Then according to the results of kettle body to account for the design, determine the reaction vessel with 2 cubic meters, on this basis, we design and select various parts of the reactor body, at last, we give the technique of production response flow diagram, the workshop general arrangement and the reaction body assembly drawing.
