丁二酸酐性能及各种生产工艺介绍

摘要

Succinic anhydride was a kind of widely used and important fine chemical raw materials , especially its derivatives of high value -added fine chemical products , succinic anhydride production process in all the world mainly divided into succinic acid dehydration and maleic anhydride hydrogenated to succinic anhydride .The properties, the application and production technology of succinic anhydride , and comparison of production technology , maleic anhydride melting catalytic hydrogenated to succinic anhydride were mainly introduced , which was one of the most competitive and promising development method due to the cost of production and the comprehensive energy consumption was low .%丁二酸酐是一种重要的精细化工原料，用途广泛，尤其它的衍生物更是附加值高的精细化工产品，全球丁二酸酐的生产工艺主要有丁二酸脱水法、顺丁烯二酸酐催化加氢法。本文章主要介绍了丁二酸酐的性能、用途和生产工艺技术，并对生产工艺技术进行了比较，顺丁烯二酸酐熔融催化加氢法由于生产成本和综合能耗较低，是最具竞争力，发展前景看好的一种方法。
