ABSTRACT:
1,6-Hexanediol is manufactured by hydroformylation of 1,3-butadiene by a process wherein an acetal of pent-3-en-1-al is formed in a first hydroformylation step in the presence of lower alkanols or alkanediols and of rhodium catalysts, and is then converted into 1,6-hexanediol in a second hydroformylation step in the presence of cobalt catalysts, followed by hydrogenation.
