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.
异丁烯、异戊二烯和丁二烯可以通过C4和/或C5烯烃的脱氢反应获得。C4和/或C5烯烃可以通过C4和C5醇的脱水反应获得,例如,通过热化学或发酵过程从生物质制备的可再生C4和C5醇。异戊二烯或丁二烯可以聚合形成诸如聚异戊二烯、聚丁二烯、合成橡胶(如丁基橡胶)等聚合物。此外,丁二烯可以转化为单体,如甲基丙烯酸甲酯、己二酸、己腈、1,4-丁二烯等,然后可以聚合形成尼龙、聚酯、聚甲基丙烯酸甲酯等。
