Claim:
1. A process for the preparation of a crude reductive carbonylation product comprising contacting hydrogen, carbon monoxide, and an alcohol having 1 to 3 carbon atoms in the presence of a catalyst to form said crude reductive carbonylation product comprising homologous aldehyde equivalents in a higher mole percent than homologous acid equivalents or homologous alcohol equivalents, each based on the total moles of said homologous aldehyde equivalents, said homologous acid equivalents, and said homologous alcohol equivalents; wherein said catalyst consists essentially of a complex of cobalt, iodide, and an onium cation or alkali metal cation of the general formula Y wherein Y is said onium cation or alkali metal cation and said onium cation is of the general formula (I) or (II) wherein X is selected from the group consisting of phosphorus (P) and nitrogen (N); R wherein said crude reductive carbonylation product comprises less than 0.1 weight percent of methyl iodide, based on the total weight of said crude reductive carbonylation product.
