Abstract:This study reports the selective obtaining of butanediols, mainly 23BDO and 12BDO isomers, by C−O hydrogenolysis of erythritol on Ru (2 %wt.) supported on titania at 473 K and 25 bar H2 and their modification with Re species that improve the selectivity to C−O hydrogenolysis over other reactions (C−C hydrogenolysis, dehydration, etc). The dependence of the catalytic activity with reaction temperature and reactants concentrations is also discussed. Characterization by XPS, TEM and TPR indicates that the surface… Show more
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.
