Practically simple reactions convert hydrocarbons to precious chemicals 2018-11-11T05:00:00Z Such approaches would reduce the energy intensity of alkene production by a factor of 2 or 3, until membranes become good enough to replace distillation entirely. Seven chemical separations to change the world 2016-04-25T04:00:00Z I started my independent research looking at alkene polymerization; in particular, the polymerization of norbornene into poly-norbornene, which is often used as a test substrate for catalysis. Q&A: The bond shifter 2013-10-16T17:21:33.257Z The name of an alkene is derived from the name of the alkane with the same number of carbon atoms. Chemistry 2019-02-14T00:00:00Z For example, halogens add to the double bond in an alkene instead of replacing hydrogen, as occurs in an alkane: Chemistry 2019-02-14T00:00:00Z Benzene does not, however, exhibit the characteristics typical of an alkene.
