Abstract

Acetaldehyde is prepared by reacting methanol with a mixture comprising hydrogen and carbon monoxide, which mixture comprises at least 25 mol percent hydrogen, in the presence of cobalt, an ionic iodide and a halogen-containing promoter which is different from the ionic iodide. The reaction is best carried out at a temperature of at least 165 DEG C. and with a ratio of gram-ions of I- originating from the ionic iodide to gram-atoms of cobalt of at least 5 and a ratio of gram-atoms of halogen from the halogen-containing promoter to gram-ions of I- in the range of about 0.001 to about 0.
