Product 1

HCID 61014Ethylene brassylateYield 73.2%

Procedure

A mixed metal catalyst prepared similarly to that of Example X, except that sodium stearate was substituted for the potassium stearate and ethyl cellusolve replaced with diethylene glycol monoethyl ether, was employed for the continuous depolymerization of poly(ethylene brassylate) in accordance with the procedure and conditions of Example I. Ethylene brassylate was continuously produced and distilled from the reactor at a rapid rate and the overall yield was 73.2%. Comparable results are obtained with a catalyst comprised of sodium benzoate and aluminum tricellusolve (Al(OCH2CH2OC2H5)3).
