Chemical properties Colorless crystal. It smells of phenol. Soluble in about 40 times water (water solubility of 3% at 40 ° C, 5.3% at 100 ° C). Soluble in caustic soda and almost all commonly used organic solvents. Uses for the manufacture of herbicide dimethyl tetrachloride, production of sebacic acid diluent, disinfectant, pharmaceutical intermediates. It is also used in the production of resins, plasticizers, fragrances, dyes and analytical reagents for the detection of nitrates and arsenate acids. Used in the manufacture of herbicide dimethyl tetrachloride, production of sebacic acid diluent, disinfectant, pharmaceutical intermediates. It is also used in the production of resins, plasticizers, fragrances, dyes and analytical reagents for the detection of nitrates and arsenate acids. Uses O-cresol can be used in synthetic resins, and can also be used in the production of pesticide dimethyl tetrachloride, disinfectants in medicine, fragrances and chemical reagents and antioxidants. The main synthesis methods are as follows: 1. Phenol alkylation method takes phenol and methanol as raw materials and methylates at about 4.14MPa surface pressure and in the presence of aluminum oxide catalyst. 2. O-toluidine method This method is used for reagent production, which is obtained by diazotization and hydrolysis of o-toluidine. 3. Toluene hydroxylation method.
