Reaction Steps
A 1000 ml round bottomed flask was charged with 619.9 g (0.12 mol) PEG 150 pentaerythritol and 136.3 g (0.48 mol) triple pressed stearic acid. The mass was heated to 100° C. with a N2 sparge, 1.0 g. phosphoric acid and 0.1 g. hypophosphorus acid were charged. The batch was heated to 215° C. while collecting the water of reaction, and maintained until an acid value of 9.9 was reached. The finished material was a white waxy solid having an acid value of 9.9.
