“591”催化剂有效化学成份为 NaO3SSCH2COONa(学名 S-磺基巯基乙酸二钠或羧甲基硫代硫酸酯二钠),它广泛用作酚酮缩合反应的催化剂,从而合成重要高分子单体双酚-A[1][2]。 “591”催化剂生产中化学反应过程如下: 中和:置换:两步反应可在同一反应器中连续进行。根据国外文献介绍 The effective chemical composition of “591” catalyst is NaO3SSCH2COONa, which is widely used as a catalyst for the condensation reaction of phenolic ketones to synthesize important monomer of bis Phenol-A [1] [2]. The chemical reaction in “591” catalyst production is as follows: Neutralization: Substitution: The two-step reaction can be carried out continuously in the same reactor.
