| Abstract: | Using waste materials high boiling of epichlorohydrin, zinc chloride as catalyst, high purity of 1,2,3 - trichloropropane was prepared. 2,3 - dichloropropene was prepared by elimination reaction using 1,2,3 - trichloropropane as the raw material, and the structure of the product determined via IR and NMR. The reaction temperature and time on the yield were investigated through the orthogonal experiment. The optimum reaction condition was determined. The method had advantages of mild reaction conditions, simple equipment, low pollution, low energy consumption and high yield. |
