    • 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.
    • 在溶剂和催化剂存在下,通过CCl4和偏二氯乙烯的连续反应连续生产调节剂CCl 3(CH 2 Cl 2)n Cl,其中n = 1-3(式I)的方法。 形成CCl 3(CH 2 Cl 2)Cl的反应以反应速率常数k1进行。 如果n = 1,则从反应器中连续除去CCl 3(CH 2 Cl 2))Cl。 如果n = 2,则在第二反应器中除去的CCl 3(CH 2 Cl 2 Cl 2)Cl类似地与CCl 4和CH 2 = CCl 2反应,以在具有反应速率常数k2的条件下形成和除去CCl 3(CH 2 Cl 2)2 Cl,其中摩尔量 的CCl4至CCl3(CH2Cl2)Cl反应的比值大于k2 / k1的比例。 如果n = 3,则除去的CCl 3(CH 2 Cl 2)2 Cl类似地在第三反应器中与CCl 4和CH 2 = CCl 2反应以在具有反应速率常数k 3的条件下形成CCl 3(CH 2 Cl 2)3 Cl,其中CCl 4的摩尔量 至CCl 3(CH 2 Cl 2)2 Cl反应的比例大于k3 / k2的比例。
