Participants

Reaction Steps

A 0.02M solution of an alkyl polyethylene oxide C11-15H23-31 --(CH2CH2O)15H (TERGITOL 15-S-15, Union Carbide, Danbury, Conn.) was prepared by dissolution of 0.877 g of TERGITOL in 50 mL of water. After complete dissolution, 1.664 g of tetraethyl orthosilicate (TEOS) was then added at room temperature in order to obtain a molar ratio TEOS/TERGITOL 15-S-15=8, while the solution was sonicated. The so obtained solution was cloudy. The sonication was stopped and the solution was allowed to stand for around 12 hours, until it had formed a clear colorless solution.
