摘要： A process of the type for producing 1,1,1,2,3-pentachloropropane by introducing 1,1,1,3-tetrachloropropane, chlorine, and Lewis acid catalyst, optionally in the presence of carbon tetrachloride, the improvement comprising introducing the Lewis acid as a slurry within a chlorinated hydrocarbon.

摘要： A method of producing carbon tetrachloride, the method comprising the step of reacting chlorine with chloroform in the presence of electromagnetic radiation within a reaction mixture that includes the chlorine, the chloroform, and carbon tetrachloride, where the concentration of chloroform is less than 5000 ppm by weight relative to the weight of the reaction mixture, where the reaction mixture includes at least stoichiometric levels of chlorine relative to chloroform, where the electromagnetic radiation creates chloride radicals, and where the reaction mixture is well mixed.

摘要： A process of the type for producing chlorinated propanes by reacting carbon tetrachloride with ethylene within a tank reactor that includes a liquid reaction mixture and a headspace above the reaction mixture wherein ethylene gas diffuses from the liquid reaction mixture into the headspace while agitating the reaction mixture, the improvement comprising transferring ethylene within the headspace back into the reaction mixture through a conduit within the mixing device that agitates the reaction mixture.
