Process For Dehydrohalogenation Of Halogenated Compounds
US Patent:
6380446, Apr 30, 2002
Filed:
Mar 7, 2001
Appl. No.:
09/801142
Inventors:
David William Drew - Newark DE
Terry Wayne Redwine - Ponchatoula LA
Terry Wayne Redwine - Ponchatoula LA
Assignee:
DuPont Dow Elastomers, L.L.C. - Wilmington DE
International Classification:
C07C 1725
US Classification:
570228, 570155, 570156, 570157
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.
Process For Production Of 2,3-Dichlorobutadiene-1,3
US Patent:
8026400, Sep 27, 2011
Filed:
Dec 16, 2008
Appl. No.:
12/335583
Inventors:
Terry Wayne Redwine - Ponchatoula LA, US
Assignee:
Dupont Performance Elastomers LLC - Wilmington DE
International Classification:
C07C 23/00
US Classification:
570246, 570189, 570216, 570226, 570227
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. The resultant reaction product may be easily enriched to provide a chlorinated alkene product wherein a) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the enriched chlorinated alkene product compared to b) the weight percentage of chlorinated alkenes having at least one beta-chlorine substituent and no alpha-chlorine substituents, based on the total weight of the chlorinated alkenes present in the mixture prior to chlorination is increased by at least 0. 25 wt. %.
Process For Production Of 2,3-Dichlorobutadiene-1,3
US Patent:
8030531, Oct 4, 2011
Filed:
Dec 16, 2008
Appl. No.:
12/335598
Inventors:
Terry Wayne Redwine - Ponchatoula LA, US
Assignee:
Dupont Performance Elastomers LLC - Wilmington DE
International Classification:
C07C 23/00
US Classification:
570246, 570189, 570216, 570226, 570227
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.
