Currently, the most widely used stone conservation compound is alkoxysilane. Once the hydrogen atoms in the S i H bond in the silane have been replaced with alkoxy groups, the silanes are converted to alkoxysilanes such as methoxysilanes, ethoxysilanes, propoxysilanes, butoxysilanes, etc.

Nov 9, 2014 · Alkoxysilanes are those compounds that contains an organic group bonded to a silicon but not directly, through an oxygen atom instead, like so: R−OSi(Me)X3 R − O S i (M e) X 3, common structure on silyl enol ethers.

Nov 26, 2019 · The hydrolysis rate of alkoxysilanes shows a dependence on the alkoxysilane structure (especially the organic attachments), solvent properties, and the catalyst dissociation constant and...

Silicone polymers (polysiloxanes) and other siloxane products are fabricated from alkoxysilanes (AS) and organoalkoxysilanes (OAS) through polymerization, which consists of poly-hydrolysis, re-esterification, and poly-condensation reactions.

Dec 3, 2021 · Since alcohols can be produced from biomass in biorefineries, SiO 2 depolymerization using alcohols as reagents to generate alkoxysilanes can support the cause of sustainable chemistry.

Alkoxysilanes with hydrophobic organic groups attached to silicon will impart that same hydrophobic character to a hydrophilic inorganic surface. They are used as durable hydrophobing agents in construction, bridge and deck applications.

Jan 25, 1997 · The meaning of ALKOXYSILANE is a silane compound with an alkoxy radical sometimes used as a sealant on concrete structures. How to use alkoxysilane in a sentence.

Mar 16, 2023 · We investigate the interaction of APTES with a crystalline layered silicate, ilerite, and with amorphous nonporous silica. We also studied a second silane, cyanopropyltrichlorosilane (CPTCS), terminated with a nitrile group.

In this paper, we describe a simple direction that these silanes have evolved in over the years. The trialkoxy silane moieties are directly appended to silicone polymers forming a chemical chimera of both species. Silane modified polymers.

Research into these problems resulted in the development of alkoxy functional silanes for use as adhesion promoters, crosslinkers, and hydrophobes.
