3840-18-4 - Reference Information
| Introduction | 2-methyl-2 '-amino diphenyl ether is an organic intermediate, which can be prepared from O-nitrochlorobenzene. It has been reported in the literature that it can be used for the preparation of weak acid violet red dyes. |
| preparation | 158.0 parts of O-nitrochlorobenzene, add 400 parts of diethylene glycol dimethyl ether, 6001.6 parts of polyethylene glycol, stir at room temperature for 30 minutes, then, 66 parts of potassium hydroxide and 130 parts of O-cresol are added alternately, while heating from 30 ℃ to 125 ℃, keeping the temperature and stirring for 240 minutes; Cooling to 60 ℃, slowly adding 1000 parts of water, heating to reflux, add 1.5 parts of benzyltriethylammonium chloride, add 95 parts of 85% hydrazine hydrate, add 1.5 parts of reduction catalyst, Reflux reaction for 220 minutes, the reduction reaction to the end, static stratification, remove the upper layer of water, and then add water G, the temperature was lowered to 40 ° C., the mixture was allowed to stand and layered, and the upper layer water was separated to obtain 182 parts of the product with a purity of 96.0[HPLC] and a yield of 91%. |
