| titleOfInvention | Method for preparing 2-chlorine-4, 6-dimethoxy-1, 3, 5-triazine |
| abstract | The invention discloses a method for preparing 2-chlorine-4, 6-dimethoxy-1, 3, 5-triazine, mainly comprising the following steps: firstly, mixing sodium bicarbonate, water and catalytic amounts of catalyst hydroxypropyl methyl-beta-cyclodextrin uniformly to obtain a reactive solution, wherein the mass ratio of the water and the sodium bicarbonate is 1:3-1:10;secondly, at the temperature of 0-30 DEG C, slowly dripping a methyl alcohol solution in which cyanuric chloride is dissolved in the obtained solution in the first step to generate mono-substituted triazine, wherein the mass ratio of the cyanuric chloride and the methyl alcohol is 0.3-0.6:1, the mass ratio of the cyanuric chloride and the sodium bicarbonate is 0.7-0.9:1; and thirdly, rising the temperature to 35-70 DEG C to enable the mono-substituted triazine generatd in the third step to continuously react to generate disubstituted triazine so as to obtain a mixture containing the disubstituted triazine. The raw materials used by the invention has low price, the cost of production materials is reduced. Compared with the prior art, the invention has simple process, higher yield of target products and is more suitable for industrialized production. |
