Abstract
Acetaldehyde is prepared by reacting methyl acetate and/or dimethyl ether with carbon monoxide and hydrogen in the presence of a palladium catalyst and an iodine moiety in a reaction zone wherein the reaction mixture is in a continuous boiling state.
Claims6
A process for the preparation of acetaldehyde which comprises continuously reacting methyl acetate and/or dimethyl ether with carbon monoxide and hydrogen in a reaction zone containing a palladium catalyst and an iodine moiety at a temperature of at least about 100.degree. C. and under a pressure of at least about 25 psig, the liquid reaction mixture being maintained under continuous boiling conditions, whereby a vaporous reaction product mixture is produced from the boiling liquid reaction mixture, and continuously removing said vaporous mixture from said reaction zone.
