1. A process for producing 1,1,1,2,3-pentachloropropane, the process comprising:
(a) introducing carbon tetrachloride to a mix tank via a first inlet;
(b) introducing Lewis acid catalyst to the mix tank via a second inlet;
(c) agitating the carbon tetrachloride and the Lewis acid catalyst as a mixture within the mix tank via one or more mixing elements to form an agitated slurry;
(d) where the mix tank is in fluid communication with a reactor via a circulation loop, where the agitated slurry is continuously circulated through the circulation loop via a pump upstream of the reactor, where the pump maintains pressure within the circulation loop;
(e) introducing the agitated slurry from the mix tank to the reactor;
(f) introducing 1,1,1,3-tetrachloropropane and chlorine to the reactor;
(g) allowing, within the reactor, the 1,1,1,3-tetrachloropropane to chlorinate to the 1,1,1,2,3-pentachloropropane in the presence of the Lewis acid catalyst; and
(h) collecting a crude 1,1,1,2,3-pentachloropropane stream.
