Abstract

1,213,955. Acetaldehyde. E. I. DU PONT DE NEMOURS & CO. 4 Aug., 1969 [5 Aug., 1968], No. 38988/69. Heading C2C. Acetaldehyde is prepared by reacting ethylene and oxygen with an aqueous solution containing a Pd(II) compound catalyst, a redox copper salt, chloride or bromide ions, and a vanadium compound at a concentration effective to catalyse the destruction of byproducts which are precursors of oxalic acid. The ethylene and oxygen may be reacted separately or simultaneously with the aqueous solution. A further solvent such as acetic acid may be present. HCl may be fed to maintain acid conditions.
