ABSTRACT:
Disclosed are processes for the preparation of glycolaldehyde in which formaldehyde is contacted with carbon monoxide and hydrogen in the presence of a rhodium catalyst and a solvent containing at least one N,N-dihexylbutyramide. The glycolaldehyde product is recovered by extraction with water. The process provides high selectivity to glycolaldehyde and efficient separation of hydroformylation products from the solvent and rhodium catalyst.
