摘要: 研究了纤维膜聚结技术用于脱除双酚A反应液中残留游离酸的实验条件和纤维膜床层的再生条件。结果表明,在聚结温度70 ℃、95%乙醇用量2%、空速20~30 h-1、纤维膜床层体积1.0 cm3的条件下,可使双酚A反应液的酸度从0.014 mmol/L脱除至≤0.001mmol/L,满足双酚A反应液对酸度的要求;当双酚A反应液的处理量达到纤维膜床层体积的60倍时,床层必须采用丙酮进行再生;在丙酮用量6 mL和再生温度50 ℃的条件下,纤维膜床层可以得到完全再生。

Abstract: The influence of reaction and recycling conditions for coalescence removal of residual free acid from bisphenol A resultant with fiber membrane were investigated. The experiment results showed that at 70 ℃,2% ethanol added,space velocity 20~30 h-1 and 1.0 cm3 fiber membrane bed,the bisphenol A resultant acidity decreased from 0.014mmol/L to 0.001 mmol/L,which met the acidity requirement for bisphenol A resultant . When the disposal amount of bisphenol A resultant reached 60 times of the fiber membrane layer volume,the layer must be recycled with acetone. By experiments,the best recycling temperature was 50 ℃ and acetone dosage was 6 mL.

Key words: bisphenol A resultant, residual free acid, fiber membrane bed, coalescence removal of acid, regeneration
