A dramatic increase in the hardness of dried cancrinite products occurs after treatment with tetraethyl silicate (TES). Soaking the can-crinite-clay mixture in TES for several hours, either at room temperature or at 100 °C, gives a product which is difficult to scratch and which is more water resistant. Samples treated with TES do not appear to soften even when soaked in water for months. [Pg.121]

Alcohol Medium Silica was obtained from tetraethyl silicate in a water-alcohol medium at room temperature, dried at 385K for 20 h, and calcined for 16 h at 875K. Silica was impregnated with aluminum isopropoxide solution in benzene. After Id exposure to air, benzene was evaporated, and the product was subjected to slow hydrolysis. [Pg.600]

TETRAETHYL SILICATE (78-10-4) Forms explosive mixture with air (flash point 99°F/37°C). Reacts slowly with water, forming ethyl alcohol. Violent reaction with strong oxidizers. Incompatible with strong acids, nitrates. Attacks some plastics and rubber. [Pg.1133]

A particularly neat way to make very pure oxide dispersions was devised by Stober, Fink and Bohn in 1968. Tetraethyl silicate was dissolved in alcohol and reacted with water in the presence of acid catalyst. Very fine nuclei of silica were formed, but these aggregated immediately to form uniform spherical clusters 159 nm in diameter which could then be grown further by controlled addition of tetraethyl silicate. The final particles were porous and of high surface area... [Pg.240]

Some of the more unusual curing agents include phenolic resin, quinone dioxime, ma-leimide, diamine, dusocyanate, tetraethyl silicate, and triallyl isocyanurate. These are limited to very specific polymer systems. [Pg.191]

However, this now appears unlikely. Ion-free silica was prepared by Goodman. and Gregg (348) for a careful study of sintering silica free from impurities. The gel was made by hydrolyzing tetraethyl silicate (tetraethoxysilane). The. micropore diameter remained constant at 6.0 0.3 A from 200 to 800°C, whereas the surface area and pore volume decreased in a similar manner, their ratio remaining constant. The surface arM dropped from about 700 to 450 m g as the gel shrank in three dimensions. [Pg.546]

The so-called RTV-2 method — room temperature vulcanization of a two component system — adds a crosslinking agent such as tri-or tetraalkoxysUane and a metallic salt catalyst to hydroxyl terminated polysiloxane precursors. The hydroxyl end groups react with the silicic ester, e.g., tetraethyl silicate, in a condensation reaction and ethanol is liberated. This condensation reaction is catalyzed by stannous-based catalysts such as dibutyltindilaurate. [Pg.869]
