Versuchsvorschrift
In operation of process 310, 1,1-dichloropropene is fed to chlorination reactor 302 and chlorinated in the presence of a catalytic amount of aluminum chloride to produce 1,1,1,2,2-pentachloropropane, 1,1,1,2-tetrachloropropane intermediate, and anhydrous HCl as a byproduct. The HCl and excess chlorine is fed to HCl purification unit 304 where anhydrous HCl is purified and taken as the overhead stream. The bottom stream comprising Cl2 is then recycled back to reactor 302. The bottom product stream of chlorination reactor 302, comprising 1,1,1,2,2-pentachloropropane, 1,1,1,2-tetrachloropropane, and heavies is quenched to remove aluminum chloride in the aqueous phase. The organic product is dried in drying unit 306 and the dried stream provided to separation unit 318.
