摘 要：鄰苯二甲酰亞胺是一種重要的精細化工中間體，被廣泛用于醫藥、農藥、染料等領域，近年來，國內產量已不能滿足其迅猛增長的需求量，每年都需要進口一定數量的產品。加入有機溶劑的尿素合成法是一種能得到高純度鄰苯二甲酰亞胺的合成方法。其在低溫、常壓下反應，反應過程中升華物較少，在一定程度上改善了生產環境，縮短了反應時間并節省了加熱能源。溶劑的加入使原料能夠混合均勻，反應放出的熱量能夠被及時帶走。本文主要探討了選用合適的溶劑來改善原料及產品的分散和接觸條件，以便更好地控制反應溫度，并且考察了反應體系的溫度、反應時間、溶劑用量、反應物配比等工藝條件對收率的影響以及三廢的處理。

關鍵詞：鄰苯二甲酰亞胺；溶劑；工藝條件；收率

 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.
