WebAbstract. The catalytic hydrogenolysis of softwood lignins is normally conducted at temperatures below 200 °C but tends to provide monomer yields of less than 30 mol% as a consequence of the non-cleavable 4-O-5 and condensed (C–C) linkages of phenylpropane units in lignin.In the present study, catalytic hydrogenolysis at higher temperatures … WebThe most commonly used adhesion promoters are HMDS (hexamethyldisilazane), Ti-Prime and diphenylsilanediol-derivatives (AR 300-80). HMDS binds to water-free surfaces via its Si-atom to the oxygen-atoms of oxidised substrates and under elimination of ammonia. A “wafer-thin” oxide-layer is thus present on basically all silicon surfaces.

Hexamethyldisiloxane (HMDSO) is an organosilicon compound with the formula O[Si(CH3)3]2. This volatile colourless liquid is used as a solvent and as a reagent in organic synthesis. It is prepared by the hydrolysis of trimethylsilyl chloride. The molecule is the protypical disiloxane and resembles a subunit of … See more Hexamethyldisiloxane can be produced by addition of trimethylsilyl chloride to purified water: 2 Me3SiCl + H2O → 2 HCl + O[Si(CH3)3]2 It also results from … See more HMDSO is used as an internal standard for calibrating chemical shift in H NMR spectroscopy. It is more easily handled since it is less volatile than the usual standard tetramethylsilane but still displays only a singlet near 0 ppm.
