Participants

Reaction Steps

Following the procedure of Example A, 78.2 g (0.575 mole) pentaerythritol and 335.3 g (0.986 mole) behenic acid were reacted for 2 hours at 200° to 210° C. in the presence of 0.25 g tin powder. 72.0 g (0.49 mole) adipic acid and 0.25 g tin powder were then added to the reaction mixture before it was heated for another 2 hours to 210° C. in an increasing vacuum (final pressure 10 to 20 mbar). After filtration under pressure and cooling, the pentaerythritol adipate behenate (7:6:12) (material C; 345 g) was present as a pale yellowish, slightly brittle, wax-like mass (dropping point 70.0° C.; acid number 0.92; saponification number 230.1; hydroxyl number 40.6).
