Separation and Identification of Molecular Species by GC-MS for the Reaction Mixture with Methyltrimethoxysilane (MTMOS)
Virgil Badescu
Abstract:This article aimed to separate and identify molecular species obtained in the sol-gel process by gas chromatography coupled with mass spectrometry (GC-MS), for the reaction mixture with methyltrimethoxysilane (MTMOS). In the presence of an unhydrolyzed methyl group, the molecular species starting with the cyclic trimers, a series of geometric isomers were separated and identified due to the position of the methyl groups in relation to the ring plane of each siloxane molecule; in addition, for the hydrolyzed pr… Show more
