Paragraph 0037-0044, (2020/03/12)
The invention provides a 1,1,1-trichloroacetone preparation method, which comprises the following steps: 1, adding monochloroacetone and an alkaline compound into a large amount of an aqueous solutionwithout other organic solvents; 2, forming an aqueous solution or a turbid liquid from the alkaline compound in water while stirring; 3, introducing chlorine gas while stirring until the solution isclear; and 4, in the whole reaction process, controlling the temperature at 0-25 DEG C. According to the invention, the method is simple in process, convenient to operate, high in yield and convenientfor industrial production, and can effectively control the acetone chlorination position, so that the generation of byproducts such as 1,1,3-trichloroacetone, tetrachloroacetone, pentachloroacetone and the like is reduced, and the purity of the prepared product is high and can reach more than 85% without further purification.
