  • PROCESS FOR PRODUCTION OF 2,3-DICHLOROBUTADIENE-1,3
    Publication number: 20110313216
    Abstract: 2,3-dichlorobutadiene-1,3 of high purity is produced from 1,2,3,4-tetrachlorobutane by a process comprising the steps of dehydrochlorination, chlorination of the reaction product obtained in the dehydrochlorination step and subsequent separation of a 2,3-dichlorobutadiene-1,3 composition from the reaction product of the chlorination step.
    Type: Application
    Filed: August 30, 2011

  • Process for production of 2,3-dichlorobutadiene-1,3
    Patent number: 8026400
    Abstract: Purified chlorinated alkenes are produced by a process in which a mixture of i) a first chlorinated alkene that has at least one beta-chlorine substituent and no alpha-chlorine substituents and ii) a second chlorinated alkene that has at least one alpha-chlorine substituent is contacted with chlorine in an amount sufficient to further chlorinate the second chlorinated alkene, but which is insufficient to cause conversion of more than 20% of the first chlorinated alkene.

  • Process for dehydrohalogenation of halogenated compounds
    Patent number: 6380446
    Abstract: Halogenated compounds are dehydrohalogenated in a multi-stage bubble reactor wherein agitation of the reactor contents is provided by in situ generation and vaporization of reaction product having a boiling point lower than that of the reactants.
