Procedure

The procedure of Example 1 was repeated with 387.5 g (1.0 mole) of octadecyltrichlorosilane and 800 mL of heptane. Under nitrogen 508.4 g (3.10 mole) of 2-(2-(2-methoxyethoxy)ethoxy)ethanol was added at 80° C. over 4 hours. After heating the reaction for an additional 48 hours and removal of all volatile components under vacuum, 780 g of the pale yellow liquid product were obtained.
