HCID 61014Ethylene brassylateYield 89.3%

Procedure

Aluminum tripelargonate, obtained by reacting 0.5 mole aluminum isopropoxide and 1.5 mole pelargonic acid at 120° C., was combined with an equimolar amount, based on aluminum, of potassium stearate and the resulting mixed metal catalyst (1.7 weight percent) charged to a reactor with 76 grams poly(ethylene brassylate). The depolymerization was conducted in the usual manner. Ethylene brassylate was obtained at a rate of 42 mls/hour and yield of 89.3 percent.
