Abstract
Process for the preparation of acetoxybutanal by reaction of allyl acetate with carbon monoxide and hydrogen under pressure and at elevated temperature, in the presence of a metal carbonyl compound. The reaction is carried out at 130.degree. to 180.degree. C and at concentrations of allyl acetate of less than 20% by weight, relative to the liquid phase. High yields are obtained.
