摘要： Production of chloroprene by treating 3,4-dichlorobutene-1 with an anion exchange resin to effect dehydrochlorination of 3,4dichlorobutene-1. Furthermore, chloroprene can be produced by treating a mixture of 3,4-dichlorobutene-1 and 1,4dichlorobutene-2 with an anion exchange resin, whereby 3,4dichlorobutene-1 is dehydrochlorinated preferentially.

摘要： Chloroprene is produced by reacting 3,4-dichlorobutene-1 with a base in the presence of thiodiphenyl amine and 2,6-di-tertiarybutyl-p-cresol and preventing clogging of the equipment.3,4-Dichlorobutene-1 is produced by an isomerization of the reaction mixture obtained by a chlorination of excess of butadiene wherein higher boiling compounds are separated before a separation of the unreacted butadiene.

摘要： A process is described whereby 2-chlorobutadiene-1,3 is produced from 3,4-dichlorobutene-1 in a two-phase reaction system wherein the reaction predominantly occurs in the organic phase and the production of undesirable by-products, particularly 1-chlorobutadiene-1,3 and acetaldehyde, is suppressed. The practice of the process results in a brine effluent from the reactor containing small amounts of organic materials resulting in a waste product which is less polluting and more easily cleaned.The organic phase is selected from primary and secondary alcohols, alkoxyethanols and mixtures thereof, preferably alkoxyethanols wherein the alkyl group has two or more carbon atoms. Surprisingly, I have discovered that the selection of the organic phase of the reaction system is made by a screening test wherein a two-phase system of a 20% brine and 3,4-dichlorobutene-1 is prepared and the alcohol or alkoxyethanol being investigated is added to obtain equilibrium in the system. Materials selected as the organic phase material are selected from those where the product of the weight percent water in the organic phase and weight percent alcohol being investigated in the organic phase is greater than 200.

摘要： A PROCESS IS PROVIDED FOR SEPARATING 2-CHLORO-1,3-BUTADIENE, CHARACTERIZED BY EXTRACTIVE DISTILLATION OF A MIXTURE COMPRISING 2-CHLORO-1,3-BUTADIENE AND ONE OR MORE CHLORINATED HYDROCARBONS, THE BOILING POINT THEREOF BEING CLOSE TO THAT OF 2-CHLORO-1,3-BUTADIENE, WITH DIMETHYL SULFOXIDE ALONE OR DIMETHYL SULFOXIDE CONTAINING WATER UP TO ABOUT 10 PERCENT BY WEIGHT AS A SOLVENT. THE PROCESS OF THIS INVENTION IS ESPECIALLY USEFUL FOR SEPARATING 2-CHLOR-1,3BUTADIENE FROM A CHLORINATED HYDROCARBON MIXTURE WHICH CONTAINS MAINLY 2-CHLORO-1,3-BUTADIENE AND TRANS-2-CHLORO2-BUTENE AND/OR 2-CHLORO-1-BUTENE.
