Novel epoxy-functional alkoxysilanes have, for example, formulae II, III, IV, V, and VI. 

Epoxy-functional alkoxysilanes, method for the production and use thereof

A process can prepare a colourless, methanolic solution of 3-(N-benzyl-2-aminoethyl)aminopropyltrimethoxysilane hydrochloride. The process includes, in step 1 fractionally distilling the vinylbenzyl chloride reactant component with addition of at least one stabilizer, and in step 2, metering and mixing the distillate (vinylbenzyl chloride) from step 1 into an initial charge of N-(2-aminoethyl)-3-aminopropyltrimethoxysilane and methanol in a molar ratio of the N-(2-aminoethyl)-3-aminopropyltrimethoxysilane to vinylbenzyl chloride of 1.0:0.80 to 1.0:1.15 and at a temperature in the range from 40 to 60&#xb0; C. and leaving them to react further. The colourless, methanolic solution has an APHA colour number of &#x3c;200 mg Pt&#x2014;Co/l.

The present invention relates to a process for preparing aqueous hydrolysates of aminoalkyltrialkoxysilanes by

Method for producing aqueous hydrolysates from aminoalkyltrialkoxysilanes

The invention relates to novel quaternary amino alcohol functional organosilicon compounds, aqueous compositions containing the latter, and a method for their production, in particular in the form of oligomers and polymers which can be present in the partially or fully hydrolyzed form and are in particular water-soluble. The compositions comprise only an extremely small portion of VOCs. The invention further relates to their use, preferably in the production of inkjet photographic papers.

Quaternary amino alcohol functional organosilicon compounds, composition containing the latter and their production and use

A composition containing 2-ethylhexyl silicate, is produced by heating a reaction mixture of ethyl silicate with an excess amount of 2-ethylhexanol in the presence of titanium tetrabutoxide as catalyst to a temperature below the boiling point of 2-ethylhexanol while mixing, allowing the reaction mixture to react and, after the reaction, removing ethanol and excess 2-ethylhexanol from the reaction mixture by distillation and obtaining the composition containing 2-ethylhexyl silicate.

The invention relates to a composition comprising olefinically functionalized siloxane oligomers derived from olefinically functionalized alkoxysilanes and optionally alkoxysilanes functionalized with saturated hydrocarbons, and also, optionally, a tetraalkoxysilane, which have not more than one olefinic radical on the silicon atom, and whose chloride content is reduced, and also to processes for preparing them and to the use thereof.

Low chloride compositions of olefinically functionalised siloxane oligomers based on alkoxysilanes

The invention relates to a composition and to a process for producing the composition comprising essentially water-soluble (meth)acrylamido-functional siloxanols, and to the use thereof.

Easily synthesizable, spontaneously water-soluble, essentially voc-free, environmentally friendly (meth)acrylamido-functional siloxanol systems, process for preparation thereof and use

Process for preparing (meth)acrylamido-functional silanes by the reaction of aminoalkyl alkoxysilanes with acrylic acid anhydride

The invention relates to a composition containing olefinically functionalized siloxane oligomers which are derived from olefinically functionalized alkoxy silanes and optionally alkoxy silanes functionalized with saturated hydrocarbons and optionally a tetraalkoxysilane, at most comprising an olefinic group on the silicon atom having a reduced chloride content and the VOC content being lower with respect to the hydrolysable alkoxy-groups. The invention also relates to methods for the production thereof and to the use thereof.

The present invention relates to a hydraulically setting mixture comprising: a) 6% to 25% by weight of cement, b) 50% to 90% by weight of at least one aggregate, and c) 0.01% to 8% by weight of at least one fluoroorganyl-substituted silicon compound, and also to materials produced from this mixture, more particularly components, concrete articles or mouldings. The invention further relates to the use of a hydraulically setting mixture of the invention for producing materials, more particularly components, concrete articles or mouldings, for example as facing concrete, where the surface of the materials exhibits only relatively low soiling tendency ('easy-to-clean' property) even on abrasion.
