摘要 在酸催化作用下,以聚酯生产过程中副产的乙醛和苯酚为原料,通过缩合反应制备双酚E,并对其工艺条件进行优化。结果表明,优化后的工艺条件为:催化剂为80%的硫酸水溶液、苯酚:乙醛:硫酸的摩尔比为5:1:2、反应温度为20℃、反应时间为2 h,在最优工艺条件下,乙醛转化率为94.7%,双酚E收率为84.6%,纯度为99.5%。该工艺中催化剂和溶剂能循环使用,副产物仅为水,在两相体系中较易分离回收。

Abstract: Under the action of acid catalysis,acetaldehyde and phenol,which are by-products in the polyester production process,are used as raw materials to produce bisphenol E through a condensation reaction.The optimized process conditions are obtained in the experiment:sulfuric acid aqueous solution with a mass fraction of 80% is used as the catalyst,the molar ratio of phenol:acetaldehyde:sulfuric acid is 5:1:2,the reaction temperature is 20℃,and the reaction performs for 2 h.Under the optimal process conditions,the conversion rate of acetaldehyde reaches 94.7%,the yield of bisphenol E is 84.6%,and the purity of bisphenol E is 99.5%.As for this process,the catalyst and solvent can be recycled,water is the sole by-product and is easier to be separated and recovered in the two-phase system.
Key words:  bisphenol E    acid catalysis    acetaldehyde by-product
