Abstract

Liquid saturated chlorinated hydrocarbons of the formula CCl3(C2H4)nCl where n is an integer ranging from 1 to 4, are produced by reacting one part by weight of ethylene with at least 50 parts by weight of carbon tetrachloride in the presence of a per-oxygen compound as catalyst. The reaction temperature may be from 20 DEG to 200 DEG C. and at low reaction temperatures the pressure may vary from below atmospheric pressure to 100 pounds per square inch, while at higher reaction temperatures it may vary from atmospheric pressure to 400 pounds per square inch. Specified per-oxygen compounds are benzoyl peroxide, acetyl peroxide, hydrogen peroxide, acetone peroxide, acetyl benzoyl peroxide, lanroyl peroxide, urea peroxide, diethyl peroxide, t-butyl hydroperoxide, perbenzoic acid, potassium persulphate, ammonium persulphate, and barium peroxide. In examples: a closed vessel containing carbon tetrachloride, ethylene and benzoyl peroxide is heated at 70-80 DEG C. (example 1) and at 70-75 DEG C. (example 2) more ethylene gas being introduced to maintain the pressure at 100 pounds per square inch (example 1) or 25 pounds per square inch (example 2). The products are separated by fractional distillation yielding tetrachloropropane, tetrachloropentane and higher boiling products. Tetrachloroheptane is also specified as a product of the reaction. U.S.A. Specification 2,334,195 is referred to. Reference has been directed by the Comptroller to Specification 581,899.ALSO:Liquid saturated chlorinated hydrocarbons of the formula CCl3.(C2H4)n.Cl, where n is an integer ranging from 1 to 4, are produced by reacting one part by weight of ethylene with at least 50 parts by weight of carbon tetrachloride in the presence of a per-oxygen compound as catalyst.
