intersolubility critical temperature临界互溶温度
In the solvent extraction process, water concentration in caprolactam-benzene solution is incremental with increasing of caprolactam concentration in caprolactam-benzene solution owing to the intersolubility of water-benzene-caprolactam. And then hydrosoluble impurities can get into organo-phase through water.
分析表明,在溶剂萃取过程中,由于水-苯-己内酰胺间的互溶性,随着己内酰胺/苯溶液中己内酰胺质量浓度的增加,水在己内酰胺/苯溶液中的含量也增加,从而引入了水溶性杂质。
