Reaction Steps
A 1000 ml round bottomed flask will be charged with 620 g. (0.24 mol) PEG 75 pentaerythritol and 272 g. (0.96 mol) triple pressed stearic acid. The mass will be heated to 100° C. with a N2 sparge, 1.0 g. phosphoric acid and 0.1 g. hypophosphorus acid will be charged. The batch will be heated to 215° C. while collecting the water of reaction, and maintained until an acid value of less than 10.0 is reached. The finished material will be a white waxy solid.
