production method | by resection 3, the industrial dimethyl phenol residue after the 5-dimethyl phenol fraction is obtained by cutting a 223-226 ° C. Fraction in a rectification column, cooling, crystallizing and centrifuging. In addition, using O-xylene as a raw material, through sulfuric acid sulfonation, and then alkali fusion, acid analysis, distillation, 3,4-dimethyl phenol can also be obtained. |
