摘　　要：以苯胺作为溶剂,对M(2-巯基苯并噻唑)进行结晶精制,可将粗M中的大部分胶体去除掉。设计了苯胺单程循环和多程循环2种流程,并分别给出结果数据。实验结果表明,精制后M的熔点可达到180℃以上,产品纯度高,无废水、废渣产生。该方法基本上能达到与酸碱处理相同的结果。With aniline as the solvent, most of the gel in the crude M （2-mercaptobenzothiazole） can be removed by crystallization refining. Two kinds of flows including one-way cycle and multi-circulation process are designed and the results are given,respectively. The experimental results show that the melting point of M after refining can reach up to 180℃ with high purity. No waste water and residue are produced. This method can achieve the same results as the acid treatment.
