年产80吨安定车间工艺设计 ——环合、精制工段 商鹤群 应用化学专业 应化0702班 学号070105040 指导教师　周莉莉讲师 摘　　要 安定，又名地西泮。英文名为diazepam；Valium。属于苯二氮卓类杂环类化合物，是一种镇静催眠药。有镇静、催眠、中枢性肌肉松驰及抗惊厥、抗癫痫作用。 本次设计为年产80吨安定车间工艺设计—环合精制工段。本设计工艺采用的工艺路线为以对硝基氯苯和苯乙腈为原料经过缩合反应，得到中间体异噁唑，再经过甲化、还原、酰化三步反应得到中间体甲基酰化物，最后经过环合、回收、精制等工段，得到了安定成品。其生产工艺流程可以分为六段,即缩合、甲化、还原、酰化、环合、精制工段。本文主要设计环合、精制两个工段。经过物料衡算，能量衡算。设备的选型及管道设计，设计出能够满足生产要求的安定生产的环合、精制生产车间。设计所得成功主要由设计说明书和设计图纸，其中图纸包括车间设备平面布置图、工艺流程图、主要设备装备图。 关键词：安定 环合 精制 工艺设计 A Technology Design For 80 Tons Dizepam Produced Per Year ——Cyclization, refined section Abstract Stability, also known as diazepam. English called diazepam; Valium. Belongs to benzodiazepine class of heterocyclic compounds, is a sedative hypnotic. With sedative, hypnotic，central muscle relaxant and anticonvulsant, antiepileptic effect. The design for the annual output of 80 tons of stability and plant process design - refined stage of cyclization. The design process is the process route used to nitrochlorobenzene acetonitrile and benzene as raw materials by condensation reaction of the intermediate isoxazole, and then through a technology, acylation reaction of the intermediate three-step acylation of methyl objects finally, after cyclization, recycling, refining processes, has been stable finished product. The production process can be divided into Liuduan, namely condensation, a technology, reduction, acylation, cyclization, refining stage. In this paper, the design cyclization, refined in two stages. Through the material balance, energy balance. Equipment selection and pipeline design, design stability and production requirements to meet the cyclization production, refining workshop. Mainly by the success of the design from the design specifications and design drawings, including drawings, including workshop equipment, floor plan, flow chart, the main equipment and equipment plans.
