| Abstract: | In the paper,1-Chloroacetone was prepared by the new method, which was dehydrochlorination of 1,3-Dichloro-2- propanol. The effect factors of reaction activity were studied, such as active component, carrier, space velocity and temperature. The factors affecting the properties of the reaction were optimized. Zinc chloride was loaded in the active carbon as catalyst, reaction temperature was 180 ℃, space velocity was 0.8 h 1. In this situation, conversion rate reached 43.8 %, selectivity reached up to 97.3 %. The method satisfied with the request of cleaner production. |
