Process for the preparation of organosilane esters with polyols

Die vorliegende Erfindung behandelt ein Verfahren zur Herstellung von di- oder polymeren Organosilanestern, deren Esterkomponente mindestens ein Glycolrest ist und deren Si-Atome über einen Glycolrest miteinander verknüpft ist. Diese Verbindungen sind an sich bekannte Verbindungen, die als Hydraulikflüssigkeiten eingesetzt werden, jedoch stieß ihre Herstellung bisher auf erhebliche Schwierigkeiten. Das vorliegende Verfahren vermeidet diese Schwierigkeiten. Es geht von Organosilandi- oder -triglycolestern aus, die mit Di- oder Polyglycolen umgesetzt werden. Bei der Umsetzung entsteht der den Glycolen entsprechende Glycolether, der abdestilliert wird. Der Kondensationsgrad der erhaltenen Organosilan ester hängt von dem Gewichtsverhältnis des eingesetzten Organosilanglycolesters zu den Di- oder Polyglycolen ab. The present invention deals with a process for the production of di- or polymeric organosilane esters whose ester component is at least one glycol residue and whose Si atoms are linked to one another via a glycol residue. These compounds are known compounds that are used as hydraulic fluids, but their production has hitherto encountered considerable difficulties. The present method avoids these difficulties. It starts from organosilane di- or triglycol esters, which are reacted with di- or polyglycols. During the conversion, the glycol ether corresponding to the glycols is formed, which is distilled off. The degree of condensation of the organosilane ester obtained depends on the weight ratio of the organosilane glycol ester used to the di- or polyglycols.

Method for the preparation of surface-modified silica particles

A method for the preparation of a stable silica organosol in a hydrophobic organic solvent is proposed. The method comprises (a) hydrolyzing a tetraalkoxy silane, e.g. tetraethoxy silane, in an alcoholic medium in the presence of a limited amount of water and ammonia as a catalyst under controlled conditions so as to produce a silica alcosol in which the silica particles satisfy the requirements that the alkoxy groups and silanolic hydroxy groups are bonded to the silicon atoms on the surface in densities of at least 3.5 μ moles/m 2 and not exceeding 2 μ mmoles/m 2 , respectively, and the specific surface area S given in m 2 /g and the average particle diameter D given in nm of the silica particles satisfy the relationship of S×D≧5000, D being 1 nm or larger, and (b) admixing the alcosol of silica particles with an organosilicon compound selected from the group consisting of the compounds represented by the general formula R 4-n SiX n , (R 3 Si) 2 NH, or YO--(--SiR 2 --O--) m --Y, in which each R is, independently from the others, a hydrogen atom or a monovalent hydrocarbon group, X is a hydroxy group or an alkoxy group, Y is a hydrogen atom or an alkyl group, n is 1, 2 or 3 and m is a positive integer not exceeding 20, in an amount, for example, in the range from 0.01 to 10 moles per mole of the silica particles under agitation of the mixture to effect a reaction for the modification of the surface of the silica particles followed by replacement of the alcoholic medium with a desired organic solvent.
