Conditions

Temperature
130 °C

Procedure

An autoclave, as equipped with a thermometer, a stirrer, and a nitrogen-introducing tube, was charged with 74 parts by weight of dipropylene glycol monomethyl ether and 1 part by weight of sodium hydroxide powder, and the internal air of the autoclave was displaced with nitrogen, and then the charged materials were heated to 130° C. Next, 426 parts by weight of ethylene oxide was introduced into the autoclave over a period of 3 hours, and then the resultant reaction mixture was aged at 130° C. for 2 hours and then cooled, thus obtaining a dipropylene glycol monomethyl ether-ethylene oxide adduct (number-average molecular weight=1,000, average molar number of addition=1.94).
