Examples
preparation example 1
[0169] Preparation example 1 (preparation of polyglycerol derivative (A-1))
[0170] 90 parts by weight of glycerin and 1 part by weight of a 48% by weight NaOH aqueous solution as an alkali catalyst were put into the reaction vessel, and 2-ethylhexylglycidol was added dropwise thereto over 12 hours while maintaining the temperature in the reaction vessel at 100°C. 3540 parts by weight of ether (the amount of 19 mol relative to 1 mol of glycerin) was then aged for 1 hour. Thereafter, 85% by weight of phosphoric acid aqueous solution was added to terminate the reaction to obtain a polyglycerol derivative (A-1).
preparation example 2
[0171] Preparation example 2 (preparation of polyglycerol derivative (A-2))
[0172] In place of glycerin, decaglycerol was used, and the amount of 2-ethylhexyl glycidyl ether used was changed to 10 mol per 1 mol of decaglycerol. In the same manner as in Preparation Example 1, polyglycerol derivatives were obtained. Object (A-2).
preparation example 3
[0173] Preparation example 3 (preparation of polyglycerol derivative (A-3))
[0174] 1500 parts by weight of poly(20) glycerol, 2000 parts by weight of lauric acid (10 mol relative to 1 mol of poly(20) glycerol) and 1 part by weight of 48% by weight sodium hydroxide aqueous solution were put into the reaction vessel, and the , the temperature in the reaction vessel was raised to 200° C. under normal pressure, and the reaction was carried out for 10 hours. After completion of the reaction, the temperature in the reaction container was cooled to normal temperature to obtain a polyglycerol derivative (A-3).
