Abstract:
A process for the continuous production of telomers CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.n Cl where n=1-3 (Formula I) by the continuous reaction of CCl.sub.4 and vinylidene chloride in the presence of a solvent and a catalyst. The reaction to form CCl.sub.3 (CH.sub.2 CCl.sub.2)Cl proceeds at a reaction rate constant k.sub.1. If n=1, CCl.sub.3 (CH.sub.2 CCl.sub.2)Cl is continuously removed from the reactor. If n=2, the removed CCl.sub.3 (CH.sub.2 CCl.sub.2)Cl reacts similarly with CCl.sub.4 and CH.sub.2 .dbd.CCl.sub.2 in a second reactor to form and remove CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.2 Cl under conditions to have a reaction rate constant k.sub.2, wherein the ratio of the molar amounts of CCl.sub.4 to CCl.sub.3 (CH.sub.2 CCl.sub.2)Cl reacted is greater than the ratio k.sub.2 /k.sub.1. If n=3, the removed CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.2 Cl similarly reacts in a third reactor with CCl.sub.4 and CH.sub.2 .dbd.CCl.sub.2 to form CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.3 Cl under conditions to have a reaction rate constant k.sub.3, wherein the ratio of the molar amounts of CCl.sub.4 to CCl.sub.3 (CH.sub.2 CCl.sub.2).sub.2 Cl reacted is greater than the ratio k.sub.3 /k.sub.2.
