Exchange reaction between hydrogen of butanes and deuterium of deuterium bromidealuminum bromide catalyst has been studied in order to elucidate the mechanism of butane isomerization.Very little exchange reaction and no isomerization occurred when butanes were treated with deuterium bromide-aluminum bromide. In the presence of 0.1 mole per cent, of butenes, isomerization of «-butane to isobutane occurred and 82-92% of the deuterium was exchanged for hydrogen.Deuteroxyaluminum dibromide acted as a catalyst for the isomerization of «-butane; less than 6% of the deuterium underwent an exchange reaction.Mechanism of isomerization of butanes was discussed.Chicago, Illinois
An interest in organic phosphorus compounds containing in the molecule a long aliphatic group has led us to investigate methods by which such compounds may be obtained. In the work reported here general methods
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
