Abstract

Process for the production of alkenols comprising the dehydration of at least one diol in the presence of at least one catalyst based on cerium oxide, wherein said catalyst based on cerium oxide is obtained by precipitation, in the presence of at least one base, of at least one compound containing cerium. Preferably, said diol may be a butanediol, more preferably 1,3-butanediol, still more preferably bio-1,3-butanediol derived from biosynthetic processes. Said alkenols may advantageously be used for the production of 1,3-butadiene, in particular of bio-1,3-butadiene.
