Summary:The invention discloses a method for purifying hexachlorocyclopentadiene. The method for purifying the hexachlorocyclopentadiene includes the steps: firstly, distilling crude hexachlorocyclopentadiene under reduced pressure and collecting front cut fractions and rear cut fractions of two temperature sections; secondly, continuing constant-temperature stirring of the front cut fractions for 2-8 hours, performing reduced pressure distillation and mixing the front cut fractions with the rear cut fractions; and thirdly, continuing constant-temperature stirring for 2-8 hours and performing reduced pressure distillation to obtain the high-purity hexachlorocyclopentadiene. The method has excellent effects in application, the purity of the hexachlorocyclopentadiene can reach 99%, the yield can reach more than 93%, needed equipment is simple, energy consumption is low, the process is easily controlled, and the method is suitable for industrial application.
