浅谈双酚A生产工艺

Discussion of Bisphenol-A Producing Methods

双酚A是重要的化工原料,由两分子苯酚和一分子丙酮缩合而成,该反应的催化剂为酸性催化剂。通过技术革新与发展,催化工艺从最初的硫酸催化到氯化氢催化,再到最新的离子交换树脂催化。这些不同类型的催化剂在工业上的应用构成了双酚A技术发展的不同阶段,也体现了人们对环保的日益重视。本文围绕不同催化工艺的特点,结合上海中石化三井化工有限公司双酚A装置的运行情况,介绍了离子交换树脂法工艺的工业应用。

Bisphenol-A(BPA) is an important industrial chemical raw material, which is composed by phenol and acetone. The mole ratio of acetone per phenol is 1:2, and the reaction can carry out when some kinds of acidity catalyst exist. The catalyst process developed from sulfuric acid to hydrogen chloride and now to IER(ion exchange resin). The development of catalyst shows not only the development of BPA producing process but also of how people concern about environment protection. This article talks about the difference about the three kinds of catalysts and will show the performance of IER method which is used for SSMC BPA plant.
