The Partial Hydrolysis of Ethyltriethoxysilane

Locking effect: A novel insight in the silylation of montmorillonite surfaces

“…During silylation, silane molecules and hydrolyzed silanes entered Mt galleries and caused a prominent increase of the basal spacing [8]. Also, the intercalated silane molecules would hydrolyze to silanols due to the interlayer water of Mt and consequently condensation among themselves to form oligomers and/or with the two adjacent layers, simultaneously [10,11]. The silane oligomers act as pillars for expansion of Mt layers and the simultaneous condensation of silane (oligomers) with the two adjacent clay layers will fix the interlayer height to a certain value, resulting in a locking effect.…”

Investigation of hydrolysis and condensation of methyltriethoxysilane in aqueous systems

“…Some hydrolysis products of organoalkoxysilanes were analyzed and characterized in the past [24,25] by such techniques as IR [26], gas chromatography-mass spectroscopy and 29 Si NMR [27][28][29].…”

Architecture of Silsesquioxanes

“…The applicability of oligosilsesquioxanes has been initially hindered by their time-consuming synthesis, which for some structures could require months to achieve moderate product yields (Sprung and Guenther 1955b). However, the synthesis methods have been much improved through the years, and many types of silsesquioxanes can now be synthesized in good yields in a short time (Kaneko et al 2012a).…”
