Dibenzyl adipate

反応条件: temp:80.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A 3 L flask equipped with a stirrer, a thermometer, and a dehydration tube was charged with 438 g of adipic acid, 779 g of benzyl alcohol, and 5.7 g of paratoluenesulfonic acid monohydrate, and the components were reacted at 120° C. for 4 hours under a reduced pressure of from 6 to 10.7 kPa, while blowing nitrogen (500 mL/minute) into a space portion. The reaction mixture had an acid value of 1.2 (KOH mg/g). Eight grams of an adsorbent KYOWAAD 500SH (manufactured by Kyowa Kagaku Kogyo) was added to the reaction mixture, and the mixture was stirred at 80° C. and 2.7 kPa for 45 minutes. Thereafter, benzyl alcohol was distilled off at a liquid temperature of from 120° to 183° C. and a pressure of 0.27 kPa, and cooled to 80° C., and the residue was filtered under a reduced pressure, to provide dibenzyl adipate as a filtrate. The resulting dibenzyl adipate had an acid value of 0.16 (KOH mg/g), a saponification value of 512 (KOH mg/g), a hydroxyl value of 1 or less (KOH mg/g), and a hue APHA of 80.
