Hexachloropropene

Chemical compound

Hexachloropropene is a compound of chlorine and carbon with the linear formula CCl₃CCl=CCl₂.^[3] 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.^[4] 1,1,1,2,2,3,3-Heptachloropropane is produced by the reaction of chloroform and tetrachloroethylene:

${\displaystyle {\ce {CHCl3 + C2Cl4 -> C3HCl7}}}$

${\displaystyle {\ce {C3HCl7 + KOH -> C3Cl6 + KCl + H2O}}}$

Hexachloropropene can be used to produce other compounds such as uranium tetrachloride, anhydrous niobium pentachloride and tungsten hexachloride.^[5]
