HCID 88851102HCID 88851102, compound

Procedure

34.0 g (0.25 mol) of pentaerythritol and 120.1 g (1.2 mol) of succinic anhydride were heated at 150° C. and stirred for 1 hour. This was cooled to room temperature, and 250 mL of ethyl acetate and 250 mL of acetone were added thereto, and left as such for 3 days. The precipitated crystal was taken out through reduced pressure filtration, and washed with a mixed solvent of equal parts of ethyl acetate and acetone to give 98.6 g of a white crystal.
