실험 절차

Into a 1000 mL reaction vessel equipped with a stirrer, a thermometer and a gas-introducing tube were charged 47 g (0.14 mol) of hydrogenated rosin (KP-610, manufactured by Arakawa Chemical Industries, Ltd.), 48 g (0.14 mol) of erucic acid, 160 g (0.28 mol) of dimerdiol (PESPOL HP-1000, manufactured by TOAGOSEI Co. Ltd.). After inner air was replaced with nitrogen, a dehydration was conducted at 240° C. for 15 hours under a nitrogen flow. After cooling, unreacted acids were removed with an aqueous sodium hydroxide solution. The resulting mixture was washed with water, and heptane, the solvent in the mixture, was distilled off to obtain 225 g of aimed hydrogenated rosin/erucic acid dimerdiol ester. The obtained hydrogenated rosin/erucic acid dimerdiol ester is in a liquid state at a normal temperature, and its acid value and hydroxyl value were 0.1 and 7.6, respectively.
