Procedure

The procedure followed that of Reference Example 4, except for use of n-octyl bromide and triethylene glycol n-butyl ether instead of butyl bromide and diethylene glycol butyl ether, respectively. Triethylene glycol n-butyl n-octyl ether (abbreviated as “TEG-BO” hereafter) was obtained by distillation (b.p.: 140-145° C. at 70 Pa). TEG-BO has a corresponding boiling point of about 350° C. under normal pressure. The solubility of glycolide in this compound at 25° C. was 2.0%.
