Organosilanes as synthetic precursors for oligosiloxanes and phenylsilica spheres

New J. Chem., 2024, Accepted Manuscript
DOI: 10.1039/D4NJ00543K, Paper
Ragini Jain, Ravi Shankar
The study describes the synthesis of disiloxanes, R3SiOSiR3, tetraorganodisiloxanes-1,3-diols, (RR1SiOH)2O, and silanol, t-Bu2Si(H)OH by AuNP-catalyzed hydrolytic oxidation of Si-H bond(s) in organosilanes. The method relies upon en route formation of...

Organosilicon compounds and their use for producing hydrophilic surfaces

Compounds of the formula where R1 each individually is identical or different and is a hydrocarbon radical, R2 each individually is hydrogen or a methyl radical, n is an integer from 6 to 11, and m is 0 or 1, with the proviso that the sum of the number of carbon atoms in the three radicals R1 in the compound of the formula (I) is 6 to 24, can be admixed with curable polymer compositions to form products with hydrophilic surfaces, or can be applied to surfaces to render them hydrophilic.

Continuous counter-current organosolv processing of lignocellulosic feedstocks

A modular process for organosolv fractionation of lignocellulosic feedstocks into component parts and further processing of said component parts into one or more of a de-lignified cellulose stream, a sugar stream, small-chain alcohol streams and four structurally distinct classes of lignin derivatives. The modular process comprises a first processing module configured for digesting lignocellulosic feedstocks with an organic solvent thereby producing a cellulosic solids fraction and a liquid fraction, a second processing module configured for recovering small-chain alcohols and optionally a first class of lignin derivatives from the cellulosic solids fraction, a third processing module configured for recovering from the liquid fraction at least one of a second class and a third class of lignin derivatives or mixtures thereof, and waste stream comprising a fourth class of lignin derivatives. The fourth processing module may optionally recover the fourth class of lignin derivatives.

Rubber composition for tire comprising an organosilicon coupling system

Tyre and rubber composition for tyre, based on at least one isoprene elastomer (for example natural rubber), an inorganic filler as reinforcing filler (for example silica) and a coupling system which provides the bonding between the said reinforcing inorganic filler and the isoprene elastomer, the said coupling system comprising, in combination: as first coupling agent, a silane sulphide compound;as second coupling agent, an at least bifunctional organosilicon compound (for example an organosilane or an organosiloxane) which can be grafted to the elastomer by means of an azodicarbonyl functional group (—CO—N═N—CO—).
