摘要： 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.%.

摘要： Isobutene, isoprene, and butadiene are obtained from mixtures of C
4 and/or C
5 olefins by dehydrogenation. The C
4 and/or C
5 olefins can be obtained by dehydration of C
4 and C
5 alcohols, for example, renewable C
4 and C
5 alcohols prepared from biomass by thermochemical or fermentation processes. Isoprene or butadiene can be polymerized to form polymers such as polyisoprene, polybutadiene, synthetic rubbers such as butyl rubber, etc. in addition, butadiene can be converted to monomers such as methyl methacrylate, adipic acid, adiponitrile, 1,4-butadiene, etc. which can then be polymerized to form nylons, polyesters, polymethylmethacrylate etc.
