FORMALDEHYDE-RESISTANT CATALYST FOR HYDROGENATING AND HYDROCRACKING ALDEHYDES, ACETALS, AND ESTERS

摘要

Rhenium has been found to be formaldehyde resistant catalyst and is thus useful in the catalytic hydrogenation of carbonyls, acetals and esters to alcohols when the reaction medium contains formaldehyde as a reactant or impurity. Also, rhenium is a useful catalyst in the hydrogenolysis of acyclic acetals to alcohols.
