Succinic Acid → HCID 86747068, compound

Participants

Reaction Steps

71.4 g (0.525 mole) pentaerythritol and 283.5 g (1.05 mole) technical stearic acid were heated with stirring for 30 minutes in a light vacuum to a temperature of 210° C. in the presence of 0.2 g tin powder. After reduction of the pressure to 12 mbar, the mixture was kept at 200° to 210° C. for 3 hours. The mixture was then cooled to 100° C. before 53.1 g (0.45 mole) succinic acid and 0.2 g tin powder were added. The mixture was then heated for 4 hours to 200°-210° C., while the pressure was slowly reduced to 19 mbar during the first 2 hours and thereafter kept at that value. Bleaching earth was then added to the reaction mixture, followed by filtration under pressure at 90° C. After cooling, the pentaerythritol succinate stearate (7:6:14) (material A; 304 g) was present as a yellowish, slightly brittle, wax-like mass (dropping point 55.1° C.; acid number 2.3; saponification number 281.5; hydroxyl number 24.9).
