Abstract
Disclosed is a process for the reductive carbonylation of methanol to produce acetaldehyde. The process includes conducting the reaction to produce acetaldehyde in the presence of a catalyst comprising a complex composed of cobalt, an onium cation and iodide in a ratio of 1:2:4, a phosphine ligand, and a phosphonium iodide. The reductive carbonylation reaction produces a crude reductive carbonylation product substantially free of methyl iodide.
