4-methoxybenzoicacidsodium - Reference Information
| use | 4, 6-dimethoxy-2-chloropyrimidine is an intermediate of pyrimidine salicylic acid herbicides, which can be used to prepare dioxalether, pyrimurium sulfide, pyrimidine oxime ether (pyribenzoxim) and other herbicides. As a pesticide intermediate, it is used in the synthesis of salicylic acid pyrimidine series herbicides; 4, 6-dimethoxy-2-chloropyrimidine is an intermediate of pyrimidine salicylic acid herbicides, which can be used to prepare dioxalether, pyrimidine sulfide, pyrimidine oxime ether (pyribenzoxim) and other herbicides. |
| Production method | The preparation method is similar to the method of preparing 2-amino -4, 6-dimethoxypyrimidine from malononitrile, where the obtained 3-amino -3-methoxy-N-cyano -2-propenidine intermediate is dispersed in toluene, and the dispersion is saturated with dry hydrogen chloride at 0°C, stir for 2h,HCl gas continues to pass in to make HCl in the solution saturated. After the reaction, water is added to layer, the water layer is extracted with toluene, toluene liquid is combined, toluene is evaporated under reduced pressure, and the finished product is dried. |
