Although phenol is a key intermediate in the plastics and polycarbonate industry, it is also a toxic component that requires removal from dilute aqueous streams, potentially by liquid–liquid extraction (LLX). For LLX, cumene is suggested as a solvent as it is already present in processes in the polycarbonate industry. For the recovery of cumene from phenol by distillation, knowledge on vapor–liquid equilibrium (VLE) behavior is important, in combination with how this is affected by other components possibly present as an impurity or explicitly added as a solvent. This was investigated in this work.

三元和四元混合物中苯酚和异丙苯的汽液行为

虽然苯酚是塑料和聚碳酸酯行业的关键中间体，但它也是一种有毒成分，需要从稀释的水流中去除，可能通过液-液萃取 (LLX)。对于 LLX，建议将异丙苯用作溶剂，因为它已经存在于聚碳酸酯行业的工艺中。对于通过蒸馏从苯酚中回收枯烯，有关汽液平衡 (VLE) 行为的知识很重要，以及这如何受到可能作为杂质存在或明确添加为溶剂的其他组分的影响。在这项工作中对此进行了调查。
