摘要
顺酐是一种重要的有机化工原料,对国内外顺酐生产工艺中回收技术的发展进行了系统回顾。介绍了部分冷凝技术和水吸收技术的发展,详细介绍了以邻苯二甲酸酯、脂环酸酯和醇3类有机溶剂为主的有机溶剂回收技术的发展。并且结合对目前广泛应用的顺酐回收技术的分析比较,提出了国内外顺酐回收技术的发展趋势以供我国发展顺酐工业之参考。
Since maleic anhydride is an important material to organic chemical industry, its recovery techniques are reviewed systematically. Developments of partial condensation and water absorption are introduced as well as organic solvents absorptionusing dialkyl phthalates, cycloaliphatic dialkyl esters and alcohols in detail. Considering the main maleic anhydride recovery teclniques being widely used nowadays, several developing trends, which may be helpful for further development of the maleic anhydride industry of our country, are presented for reference in the article.
