Procedure

These examples show that the fluorine concentration controls the structure of the final product. Five 0.02M solutions of an alkyl polyethylene oxide C11-15H23-31 --O(CH2CH2O)12H (TERGITOL 15-S-12, Union Carbide, Danbury, Conn.) were prepared by dissolution of 0.738 g of TERGITOL in 50 mL of water. After whole dissolution, 1.664 g of tetraethyl orthosilicate (TEOS) was then added, under sonication, at room temperature in every solution in order to get the molar ratio TEOS/TERGITOL 15-S-15=8. Solutions were then rested for almost 12 hours or until they had recovered a clear colorless aspect.
