Abstract: A CATALYST COMPRISING METALLIC PALLADIUM DEPOSITED ON A SILICA GEL OR ACTIVE CARBON CARRIER FOR USE IN THE HYDRATION AND DECHLORINATION OF DICHLOROACETIC ACID AND/OR TRICHLOROACETIC ACID TO PRODUCE MONOCHLOROACETIC ACID AND/OR ACETIC ACID IS REGENERATED. TO THIS EFFECT, THE POISONED CATALYST IS SUBJECTED IN THE HYDRATION ZONE ITSELF AT TEMPERATURES OF BETWEEN 50 AND 200*C. TO TREATMENT WITH DRY CHLORINE GAS UNTIL IT IS SATURATED, AND THE HYDRATION ZONE IS EXHAUSTED UNDER A PRESSURE OF BETWEEN ABOUT 500 AND 750 MM. MERCURY.

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。
