Abstract: This specification discloses a process of reacting an acetic acid derivative with ethylene in the presence of a catalyst. The acetic acid derivatives include esters, the amide, substituted amides, and the anhydride of acetic acid. The catalyst is insoluble in the acetic acid derivatives, the ethylene, and the reaction products thereof and is an oxide of manganese wherein the manganese has a valence at least as great as 3. The catalyst, following the reaction, can be separated from the reaction mixture and regenerated by heating in the presence of an oxygencontaining gas. Thereafter, the regenerated catalyst may be employed further for the reaction of an acetic acid derivative with ethylene.
