Summary

The hydrolysis of SiX4 (X = Cl, OEt), leading to SiO2 as the final product, gives a great multitude of different siloxanes and siloxanoles as intermediates. The compositions of the reaction mixtures were observed by GC-MS methods. Using certain perchlorosiloxanes as starting materials instead of SiCl4 the number of different products can be reduced. However, hydrolysis of ethoxysiloxanes leads to the cleavage of Si-O-Si bonds.
