| titleOfInvention | Method for preparing deuterated chloroform by using hexachloroacetone as intermediate |
| abstract | The invention provides a method for preparing deuterated chloroform by using hexachloroacetone as an intermediate. The method comprises the following steps: step 1, producing hexachloroacetone by monochloroacetone and/or polychlorinated acetone raw material liquid, and comprising the steps of raw material liquid pre-treatment, chlorination catalytic reaction and reaction product purification; step 2, producing deuterated chloroform by taking hexachloroacetone as raw material, and comprising the steps of hydrolytic catalytic reaction and reaction product purification. The method solves the problem of the disposing of waste material produced during the production of monochloroacetone, trichloroacetone and the like, and is in favor of relieving the environment burden; common cheap chemical is used as catalytic agent, the side reaction is less, the reaction product is easy to separate, and the content of the produced pollutant is greatly lowered. Through the utilization of the polarization and weakening effects of connecting bond of the carbonyl carbon of the hexachloroacetone and trichloromethyl, the carbonyl carbon of the hexachloroacetone and trichloromethyl are hydrolyzed in an alkalescence condition to produce deuterated chloroform, and the reaction product is CO2 that can be discharged into air directly. The method has important social benefits and economic benefits. |
