反応手順
Into 120 g of 60% NaH and 500 ml of toluene were added dropweise 329 g of butyl bromide and 486 g of diethylene glycol butyl ether at 50° C. Diethylene glycol dibutyl ether (abbreviated as “DEG-DB” hereafter) was obtained by distillation (b.p.: 256° C. under normal pressure) from the reaction mixture. The solubility of glycolide in this compound at 25° C. was 1.8%.
