摘要
邻、对苯二酚的沸点和凝固点高 ,又具有热敏性 ,产品的分离提纯难度较大。本文针对苯酚羟基化法联产邻、对苯二酚产品的分离纯化过程中 ,由于邻、对苯二酚的热敏性影响分离收率和分离能耗偏高等问题 ,就目前关注的物料热敏性问题进行了讨论 。
Because of high boiling point,high feezing point and heat-sensitivity,the separation and purification process for producing pyrocatechol and hydroquinone is full of difficulty. Aiming at the problems of heat-sensitivity, large amount of outgrowth and production loss due to thermal decomposition and high energy cost during the separation and purification process,this paper dwells on some aspects of heat-sensitive materials. Also this paper put forward directions needing deep research.
