Procedure

95.2 g (0.7 mole) pentaerythritol and 324.0 g (1.2 moles) technical stearic acid were reacted for 2 hours at 205°-210° C. in the presence of 0.3 g tin powder. The pressure was continuously reduced to 10-20 mbar and, finally, was kept at that level. After the addition of 87.6 g (0.6 mole) adipic acid and 0.15 g tin powder, the reaction mixture was heated for another 2 hours to 205°-210° C. under decreasing pressure (final vacuum 10-20 mbar). 93.6 g (0.3 mole) technical hydroxystearic acid and another 0.15 g tin powder were then added before the reaction mixture was heated for another 2 hours to 205°-210° C. The pressure was continuously reduced to a final vacuum of 10 to 15 mbar. After the addition of bleaching earth, filtration under pressure at 90° C. and cooling, the pentaerythritol adipate stearate hydroxystearate (7:6:12:3) (material M; 482 g) was present as a yellowish, slightly brittle, wax-like, slightly caking mass (dropping point 51.5° C.; acid number 1.06; saponification number 277.5; hydroxyl number 43.2).
