【摘要】 将加盐精馏和萃取精馏结合起来的加盐萃取精馏新方法,由醋酸甲酯-水体系的汽液平衡试验结果表明,盐的加入破坏了共沸点组成,加盐萃取精馏比单纯的加盐精馏和萃取精馏工艺更优。更多还原

【Abstract】 A new method of extractive distillation with salt is combined with extractive distillation and saline distillation. According to the vapor - liquid equilibrium experiment of methyl acetate -water, it can be proved that salt can break the azeotrope point. In a word, extractive distillation with salt is better than extractive distillation or with salt only.更多还原
