双酚A合成中副产物的裂解反应工艺研究

Study on Cracking Reaction of the Byproducts from Bisphenol A Synthesis Process

对双酚A合成工艺中副产物的裂解反应过程进行研究,确定了催化剂种类及用量,考察了各种因素对裂解反应的影响,获得了较佳工艺条件;并对裂解反应器形式进行了对比实验研究,结果表明,采用内衬复合金属丝网的降膜反应器比传统的釜式裂解反应器具有明显的优势。

Cracking reaction of the byproducts from the BPA synthesis process wa s studied.A suitable catalyst and its dosage was suggested.Influencing facto rs on cracking reaction was discussed,and optimal cracking conditions were also d etermined.Through comparative experimentation it was found that falling-film r e actor lined with metal gauze was more effective than conventional reactor used i n cracking process.
