Abstract: Process for converting 1,3-dichlorobutene-(2) to 2chlorobutadiene-(1,3) by uncatalyzed dehydrochlorination of the previously vaporized reactant for a period not exceeding 10 seconds and at a temperature of 450*-650* c, the resulting gases being immediately cooled to a temperature of 0*-35* c by quenching and substantially pure product recovered from the quenching liquid.
Abstract translation: 通过未催化的先前蒸发的反应物的脱氯化氢处理不超过10秒并在450-650℃的温度下将1,3-二氯丁烯（2）转化为2-氯丁二烯 - （1,3）的方法， 所产生的气体通过淬火立即冷却到0°-35℃的温度，并从骤冷液中回收基本上纯的产物。
