Abstract
Unsaturated chlorohydrocarbons are obtained by reacting trichloroethylene or perchloroethylene with methyl chloride, ethane, propylene, toluene or a xylene at 500-750 DEG C. for 0.1-10 seconds in the absence of catalyst or packing materials; the product has the same number of carbon atoms as the two starting compounds. Examples react (1) C2Cl4 with CH3Cl to give CH2Cl.CCl=CCl2; (2) C2HCl3 with CH3Cl to give CH2Cl.CH=CCl2; (3) C2Cl4 with C2H6 to give CH3CH2CCl=CCl2; (4) C2HCl3 with C2H6 to give CH3CH2CH=CCl2; (5) C2Cl4 with toluene to give PhCH2CCl=CCl2; (6) C2Cl4 with p-xylene to give 4-CH3PhCH2 CCl=CCl2; (7) C2Cl4 with C3H6 to give CH2=CHCH2 CCl=CCl2; and (8) C2HCl3 with C3H6 to give CH2=CHCH2 CH=CCl2. The last three products are claimed per se, and can be polymerized (see Division C3).ALSO:The compounds 4-CH3PhCH2CCl=CCl2, CH2=CHCH2CCl=CCl2 and CH2=CHCH2\t CH=CCl2 (see Division C2) can be polymerized by free radical initiated procedures, with e.g. diisopropyl peroxydicarbonate as catalyst at 25-80 DEG C. in argon.
