A 54 g portion of the hydrogenated product obtained in Reference Example 2 and 0.2 g of magnesium oxide were put into the same apparatus of Inventive Example 1 and the reaction was carried out under conditions of 230 to 260° C. and 1.3 kPa to 130 Pa to obtain 15.2 g of a colorless liquid distillate 3 hours thereafter. This distillate contained 2.2 g of cyclopentadecanolide (yield 94%), 0.93 g of 1,15-pentadecanediol (recovery ratio 96%) and 11.3 g of 2-decyl-1-tetradecanol. The reaction residue was a light yellow liquid having a viscosity of 85 mPa·s, and 28.4 g of di-2-decyl-1-tetradecyl pentadecandioate was recovered from the residue (recovery ratio 85%).
