Abstract
1,219,199. Acetaldehyde from vinyl acetate. FARBWERKE HOECHST A.G. 27 May, 1968 [27 May, 19671, No. 25148/68. Heading C2C. A process for the production of acetaldehyde by hydrolysis of vinyl acetate comprises passing vinyl acetate together with acetic acid, water and ethylene (oxygen may also be present) in the gaseous phase over a catalyst comprising a phosphoric acid, a heteropolyacid thereof, an acid metal salt of these acids with a metal in Groups I-V, VIA or VII A of the Mendeleef Periodic Table or with Mn, Fe, Co or Ni, the said acid salts not being volatile under the reaction conditions, mixtures of these compounds of the elements and/or mixtures of phosphoric acids with compounds of the elements of Group V A or VIA of the Mendeleef Periodic Table, which may be supported on a carrier, e.g. silicic acid. The feedstock may be the reaction gases from a process for preparing vinyl acetate from ethylene, oxygen and acetic acid.
