| titleOfInvention | Purification method and application of 1,1,3-trichloroacetone |
| abstract | The invention belongs to the technical field of compound purification, and specifically relates to a purification method of 1,1,3-trichloroacetone and its application, wherein the method comprises the following steps: (1) combining 1,1,3-trichloroacetone crude product with (2) recrystallize the upper layer solution after standing; and (3) filter out and wash the recrystallized solid crystals; wherein, the 1,1,3-trichloro The weight ratio of the consumption of acetone crude product and water is 1: (0.1-2). The method is environmentally friendly, and greatly reduces the generation of waste water, and does not produce waste organic solvents and organic waste gases; in addition, the aqueous solution of 1,1,3-trichloroacetone purified by the purification method is directly used in the production of folic acid, Side reactions are reduced, the total yield of folic acid can be increased by 5% by weight, the purity is above 99.2% by weight, and high-quality folic acid can be obtained. |
