Abstract
A process for producing a 1,3-diol, e.g., 1,3-propanediol, or a 3-hydroxyaldehyde is disclosed which comprises contacting a combination of an epoxide, carbon monoxide and hydrogen in the present of a rhodium-containing catalyst effective to promote the hydroformylation of the epoxide at conditions effective to form at least one of a 1,3-diol and a 3-hydroxyaldehyde, the contacting occurring in the substantial absence of a promoting amount of alkali metal ions, and at least a portion of the rhodium-containing catalyst being formed substantially without incorporation of the epoxide. A process for producing such rhodium-containing compositions is also disclosed.
