Hydrogenation of 1,3-Butadiene over CaO Catalyst Treated with Methanol

Article abstract of DOI:10.1246/bcsj.64.552

When calcium oxide was treated with methanol at low temperature, calcium methoxides i.e., calcium dimethoxide and, calcium hydroxide methoxide, could be easily formed.The catalyst produced by the thermal decomposition of these compounds exhibited remarkably high activity to the hydrogenation of 1,3-butadiene.With the aim to investigate the cause of the high activity, two other calcium oxide catalysts were used for a comparison.The cause was ascribed to the formation of a large amount of electron-donating sites, including both basic ones and those with a high surface area.
