邻苯二甲酰亚胺的制备研究

范文编号:HG055  范文字数:8112,页数:23

摘 要：邻苯二甲酰亚胺是一种重要的精细化工中间体，被广泛用于医药、农药、染料等领域，近年来，国内产量已不能满足其迅猛增长的需求量，每年都需要进口一定数量的产品。加入有机溶剂的尿素合成法是一种能得到高纯度邻苯二甲酰亚胺的合成方法。其在低温、常压下反应，反应过程中升华物较少，在一定程度上改善了生产环境，缩短了反应时间并节省了加热能源。溶剂的加入使原料能够混合均匀，反应放出的热量能够被及时带走。本文主要探讨了选用合适的溶剂来改善原料及产品的分散和接触条件，以便更好地控制反应温度，并且考察了反应体系的温度、反应时间、溶剂用量、反应物配比等工艺条件对收率的影响以及三废的处理。

 Research on Preparation of Phthalimide
 
Abstract: Phthalimide is an important fine chemical intermediates, widely used in medicine, pesticides, dyes and other fields. In recent years, the demand of domestic phthalimide grows rapidly,leading to domestic production can not meet the demand,and imports a certain number of products annual. Organic solvents synthesis method is a low temperature, atmospheric reaction,and is a high purity Phthalimide synthesis method. the sublimation in the reaction process is less , improve the environment, reduces the reaction time and saves heated energy , the solvent mades raw materials mix widely,  and the heat emitted from the reaction is taken away.  Discussion of the paper is on the selection of a suitable solvent to improve the raw materials and products decentralized and contact conditions, and better control of temperature, and inspected the impact of the reaction temperature, reaction time, the amount of solvent, reactant processing conditions on the yield and waste handling.

Keywords：Phthalimide; Solvent; Process conditions; Yield
