Procedure

Example 32 was repeated except that 170 g of ethyl propionate and 18.3 g of ethylene oxide were reacted using catalyst of 1.6 g of triisopropoxy aluminum and 0.51 g of triethylamine at 160° C. for 5 hours. As the result, 20.6 g of ethylene glycol ethylether propionate (yield was 35.9 % to ethylene oxide), 3.5 g of diethyleneglycol ethylether propionate (yield was 9.4 % to ethylene oxide) and 7.9 g of polyethyleneglycol ethylether propionate were obtained.
