Abstract
A process for producing a 1,3-diol, e.g., 1,3-propanediol, and/or a 3-hydroxyaldehyde, e.g., 3-hydroxypropionaldehyde, is disclosed which comprises contacting a combination of an epoxide, carbon monoxide and hydrogen in the presence of a rhodium-containing.catalyst composition 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 rhodium-containing catalyst composition comprises an anionic rhodium-containing complex. A promoter component is preferably provided to enhance at least one of the rate and selectivity of the epoxide hydroformylation reaction. Rhodium-containing compositions and a processes for producing rhodium-containing compositions are also disclosed.
