ABSTRACT:
This invention provides a process for converting alkanols into higher alkanols, e.g. methanol into ethanol, by contacting a basic solution comprising said alkanol in the absence of added hydrogen, with a catalyst comprising a lanthanum moiety. Preferably said catalyst further comprises a rhodium or a ruthenium moiety in combination with said lanthanum moiety. This invention further provides a novel heterogeneous catalyst system adapted for alkanol homologation, which comprises lanthanum hydroxide and a rhodium or ruthenium moiety, e.g. RhCl.sub.3 or RuCl.sub.3.
