Adipic Acid → HCID 86747071, compound

Participants

Reaction Steps

88 g (0.96 mole) glycerol, 121 g (0.83 mole) adipic acid, 290 g (1.07 mole) technical stearic acid, 0.5 g tin powder and 0.5 g H3PO3 were heated for 4.5 hours to 200°-210° C., initially under normal pressure. After 30 minutes' heating, a slight vacuum was applied; in the course of the next 2 hours, the pressure was reduced to 13 mbar and thereafter was kept at that value for 2 hours. After the addition of bleaching earth, the yellowish, clear reaction mixture was subjected to pressure filtration at 90° C. After cooling, the glycerol adipate stearate (8:7:9) (material H; 403 g) was present as a whitish, wax-like mass (dropping point 40.8° C.; acid number 7.1; saponification number 340.1; hydroxyl number 25.1).
