摘要
从糖精废液中回收邻氯苯甲酸粗品后,采用含乙醇50％的乙醇—水混合溶剂,进行提纯,可得到纯度高,堆积密度较大的邻氯苯甲酸结晶体。
A Process is disclosed for recovery of ortho - chlorobenzoic acid from a Saccharin waste water containing ortho - chlorobenzoate and purification of the ortho - chlorobenzoic acid by recrystaling with 50% ethanol-water mixture,filtering, washing to obtain a high purity and high accumulating density crystal.
