Usage

General Description

(TRIETHOXYSILYL)CYCLOHEXANE 98 is a chemical compound that is composed of a cyclohexane ring with three ethoxy groups and a silane moiety attached to it. It is used as a silane coupling agent in various applications such as adhesives, coatings, and sealants. (TRIETHOXYSILYL)CYCLOHEXANE 98 can enhance the adhesion and compatibility between organic and inorganic materials due to its ability to crosslink with both types of substrates. It is also used as a surface modifier to improve the hydrophobicity and the chemical resistance of materials. Additionally, (TRIETHOXYSILYL)CYCLOHEXANE 98 can be used to modify the surface of inorganic fillers and pigments to improve their dispersion and reduce their agglomeration in polymer matrices.

METHOD FOR PRODUCING ORGANOXYSILANE

PROBLEM TO BE SOLVED: To provide a method for easily producing high quality alkoxysilane without sublimating contaminant urea and urea hydroxide in the distillation of an alkoxysilane layer after separating an alcohol solution layer with urea and urea hydroxide dissolved therein when chlorosilane is reacted with alcohol in a presence of urea. SOLUTION: The method for producing organoxysilane represented by formula (3) comprises: reacting chlorosilane represented by formula (1) with alcohol represented by formula (2) in a presence of urea; removing hydrogen chloride generated by the above reaction, urea hydroxide produced by reaction of urea, and urea in a reaction system as an alcohol solution dissolved in alcohol in the reaction system from the system; and thereafter distilling an obtained organoxysilane layer with metal alkoxide added to the layer, where R1 and R2 are monovalent hydrocarbon groups, a is an integer of 1-3, b is an integer of 0-2, a+b is an integer of 1-3, and R3 is a monovalent hydrocarbon group.

METHOD FOR PREPARING DI-ORGANO-DIALKOXYSILANES

The present invention relates to a method for preparing di-organo-dialkoxysilanes, in particular di-organo-dialkoxysilanes wherein one or both of the organic substituents are bulky. The method comprises reacting a tetraalkoxysilane compound with a first Grignard reagent to form a mono-organo-tri-alkoxysilane compound, which is then reacted with a chlorinating agent to form a chlorinated mono-organo-di-alkoxysilane which is then reacted with a second Grignard reagent to form the di-organo-di-alkoxysilane compound.

Catalysis of hydrosilylation. XII. Spectrophotometric study of the reactivity of the 2-bis(diphenylphosphinoethyl)tetramethyldisiloxane complex with substrates of the hydrosilylation reaction

The reactivity of the model complex - 2 - bis(diphenylphosphineethyl)tetramethyldisiloxane (I) with the substrates of the hydrosilylation (1-hexene and triethoxysilane) has been studied spectrophotometrically at room temperature.Disappearance of the band at 24.4E+3 cm-1, characteristic for the square planar complex, I, enabled us to determine pseudo first-order rate constants (kobs) for the reaction.Relative values of kobs indicate that the reaction is four times faster with 1-hexene than with triethoxysilane.Inhibition by added siloxyphosphine (BPS-2) is evidence for preliminary replacement of phosphine by 1-hexene.Consequently, for silica-supported catalysts of the BPS ligand structure the anchored complex is released into solution during the reaction and catalyses the process homogeneously.
