摘要
吲哚美辛英文名为：Indomethacin。又名：抗炎吲哚酸，为非甾体抗炎药，具有抑制环氧酶的作用致使前列腺素的合成减少以到达抗炎、镇痛、解热作用。制止炎症组织痛觉神经冲动的形成，抑制炎性反响。至于解热作用，由于作用于下视丘体温调节中枢，引起外周血管扩X及出汗，使散热增加。
综合考虑原料药来源，反响条件，反响收率，经济合理性中间产物污染性，目标产物纯度等多个条件，找到一条最正确的反响路线，制定合理的工业生产工艺流程。本文是以对甲氧基苯肼和乙醛为初始原料经过多步反响合成吲哚美辛的，各步的收率在80％以上。
本设计为年产50吨吲哚美辛的生产车间工艺设计，主要包括产品的最正确合成路线、工艺流程的设计及工艺流程图、生产过程的物料衡算、厂区平面设计图、车间设备布置图、主要设备图等的绘制，最后是毕业设计说明书。

Abstract
Indomethacin English name: Indomethacin. Also known as: Anti-inflammatory indole acid, non-steroidal anti-inflammatory drugs inhibit cyclooxygenase role in causing decreased prostaglandin synthesis in order to achieve anti-inflammatory, analgesic and antipyretic effects. Suppression of inflammatory tissue pain nerve impulses, inhibit the inflammatory response. As for the antipyretic effect, because acting on the hypothalamus thermoregulatory center, causing peripheral vasodilatation and sweating, heat dissipation increases..

Considering the source of drug substances, the reaction conditions, the reaction yield, economic rationality intermediate pollution, and the target product purity and many other conditions, to find an optimum reaction route to develop a reasonable industrial production process. This article is based on methoxyphenylhydrazine and acetaldehyde as starting materials through multi-step reaction of indomethacin, each step yields above 80%.
The design for the annual production capacity of 50 tons of indomethacin production plant process design, including the products of the best synthetic route, process design and process flow diagrams, process material balance, graphic design factory, workshop equipment layout maps, diagrams and other major equipment drawing, and finally graduated from the design specification.
