[0148] Hereinafter, examples and comparative examples are given to explain the present invention more specifically. In addition, unless otherwise stated, the following "%" means "mass%".
Synthetic example 1
[0149] [Synthesis Example 1: Synthesis of Compound 1]
[0150] 50 g of butanol and 2.5 g of potassium hydroxide as a catalyst were added to the autoclave, and after replacing the air in the autoclave with dry nitrogen, the catalyst was dissolved at 140°C while stirring. Next, 1,317 g of propylene oxide was added dropwise with a titration device under conditions of 120°C and 0.2 to 0.5 MPa (gauge pressure), and the mixture was stirred for 3 hours. Next, a mixture of 1155 g of ethylene oxide and 247 g of propylene oxide was added dropwise with a titration device under conditions of 120° C. and 0.2 to 0.5 MPa (gauge pressure), and stirred for 2 hours. Then the reaction composition was taken out from the autoclave and neutralized with hydrochloric acid to make the pH 6-7. In order to remove the contained water, it was treated at a reduced pressure of -0.095MPa (gauge pressure) and 100°C for 1 hour to remove . Furthermore, filtration was performed in order to remove the salt produce...
Synthetic example 2
[0152] [Synthesis Example 2: Synthesis of Compounds 2-16]
[0153] Except that the starting materials and the addition amounts of ethylene oxide and propylene oxide were changed, and 1,2-butylene oxide was used as the alkylene oxide, the alkylene oxide as compound 2 was obtained in the same manner as in Synthesis Example 1. derivative. Compounds 3-16 were synthesized by the same synthetic method. According to the types of starting materials and alkylene oxides, the number of carbon atoms n of the starting materials, the average added moles of alkylene oxide, ethylene oxide, and propylene oxide (a, b, c), and the average addition Table 1 shows the y value and the random rate x obtained by the total number of moles (a+b+c) and (2n+a). In addition, the compounds 17-19 used in the following comparative examples are shown in Table 1 together.
