Hexachloropropene

Hexachloropropene is a compound of chlorine and carbon with the linear formula CCl3CCl=CCl2. It is a colourless liquid at room temperature. It is toxic for humans.

Hexachloropropene can be produced by the dehydrochlorination reaction of 1,1,1,2,2,3,3-heptachloropropane by potassium hydroxide in methanol solution. 1,1,1,2,2,3,3-Heptachloropropane is produced by the reaction of chloroform and tetrachloroethylene:

Hexachloropropene can be used to produce other compounds such as uranium tetrachloride, anhydrous niobium pentachloride and tungsten hexachloride.
