Abstract: A stable suspension of ethylpolysilicate nanoparticles having a size of between about 5 nm and 120 nm are in water and stabilized with between about 0.05 and 5 weight percent tetraalkylammonium hydroxide. The particles are between about 95% and 99.5% hydrolyzed and have superior removal rates when used in chemical mechanical polishing. A process for making ethylpolysilicate nanoparticles includes the step of adding reverse osmosis water and 25% tetramethylammonium hydroxide and ammonium hydroxide to a reactor, agitating the mixture and heating the mixture to about 80° C. Tetraethylalkoxy silane is added to the mixture and the mixture stirred and hydrolyzed. Ethanol is then removed. The mixture was then subjected to a vacuum to remove additional distillate. The material left in the reactor was then transferred to a plastic drum.

Abstract: An improved aerogel and a process for production of the same. The improved aerogel which has a significantly reduced dust (e.g., aerogel fines) and static charge, as compared with conventional aerogel products. The aerogel also has a “sticky” or “tacky” nature which can be used to attract any available dust, fines and/or particulate matter and also restrict flowability of aerogel granules, for example, out of a breached container and thereby minimize loss of the aerogel product through any breached opening.

Abstract: Esters of glyoxylic acids are formed by the oxidation of an organoglycolate ester using a hypohalide oxidizing agent, preferably under phase transfer conditions using a phase transfer catalyst. An example of a suitable oxidizing agent is sodium hypohalite, and a preferred starting material is methyl mandelate.

Abstract: Arylphosphinic acids are prepared by reacting an aromatic compound with phosphorus trichloride in the presence of aluminum chloride to form an aluminum/phosphorus complex and then hydrolyzing the complex with aqueous phosphoric acid to form the arylphosphinic acid as an insoluble phase and a soluble aluminum salt. The arylphosphinic acid and aluminum salt are then easily separated.

Abstract: Alkyl vanadates are prepared by the reaction of vanadium pentoxide and an alkyl alcohol while heating in the presence of an alkane azeotroping agent to assist in the removal of water by-product.

Abstract: Compositions containing certain polymeric alkoxysilanes and refractory materials.The polymeric alkoxysilanes comprise a polymer network having the average formula: ##EQU1## wherein each R is an independently selected hydrocarbon or hydrocarbon ether radical, each R.sup.1 is an independently selected hydrocarbon radical, and all of said radicals are free of aliphatic unsaturation: a has a value from 1 to 3; and b has a value from 0.0001 to 1.0. These polymers are made by reacting an alkoxysilane of the formula Si(OR).sub.a O.sub.4-a/2 with water and with an organosulfonic acid of the formula R.sub.1 SO.sub.3 H. The compositions are useful for the preparation of investment casting molds.

Abstract: Compositions containing certain polymeric alkoxysilanes and zinc dust.The polymeric alkoxysilanes comprise a polymer network having the average formula: ##STR1## WHEREIN EACH R is an independently selected hydrocarbon or hydrocarbon ether radical, each R.sup.1 is an independently selected hydrocarbon radical, and all of said radicals are free of aliphatic unsaturation: a has a value from 1 to 3; and b has a value from 0.0001 to 1.0. These polymers are made by reacting an alkoxysilane of the formula ##STR2## WITH WATER AND WITH AN ORGANOSULFONIC ACID OF THE FORMULA R.sub.1 SO.sub.3 H. The compositions are useful for the protection of ferrous surfaces.

Abstract: Polymeric alkoxysilanes which comprise a polymer network of the average formula ##STR1## WHEREIN EACH R is an independently selected hydrocarbon or hydrocarbon ether radical, each R' is an independently selected hydrocarbon radical, all of said radicals being free of aliphatic unsaturation, a has a value from 1 to 3; and b has a value from 0.0001 to 1.0. These polymers are made by reacting an alkoxysilane of the formula ##EQU1## WITH WATER AND WITH AN ORGANOSULFONIC ACID OF THE FORMULA R.sup.1 SO.sub.3 H. These polymers are useful in zinc-rich paints and in binders for investment castings.
