2,4-二氯-5-氟苯甲酰乙酸甲酯生产工艺改进
A Technological Investigation in Production of Methyl (2,4 Dichloro 5 Fluorobengol) Acetate
【摘要】 讨论了2 ,4二氯5氟苯甲酰乙酸甲酯生产中, 碳酸二甲酯的回收和纯化。确定了通过破坏碳酸二甲酯和甲醇的共沸现象而得到高质量的碳酸二甲酯, 回收率达82 % 。
【Abstract】 An investigation was made on the recovery and purification of dimethyl carbonate in production of methyl ( 2,4 dichloro 5 fluorobenzoyl) acetate. The high quality of the product with recovery of 82% was obtained by cancelling azeotropism of dimethyl carbonate and methanol.
