Exempel på hur du använder SILANE i en mening

• A pair of silane single bonds have significantly greater total enthalpy than a single silene double bond, so simple disilenes readily autopolymerise, and silicon favors the formation of linear chains of single bonds (see the double bond rule).
• This is often achieved through the use of specialty silane chemicals which can form a SAM (self-assembled monolayers) layer.
• In this respect, neopentane is similar to its silane analog, tetramethylsilane, whose single chemical shift is zero by convention.
• silicon sources (silane and dichlorosilane) and germanium sources (germane, germanium tetrachloride, and isobutylgermane).
• The crosslinkers used in condensation cure systems are typically alkoxy, acetoxy, ester, enoxy or oxime silanes such as methyl trimethoxy silane for alkoxy-curing systems and methyl triacetoxysilane for acetoxy-curing systems.
• The presence of traces of disilane is responsible for the spontaneous flammability of silane produced by hydrolysis by this method (analogously diphosphine is often the spontaneously pyrophoric contaminant in samples of phosphine).
• Silane is slightly denser than air, while disilane and trisilane are denser than air, thus there is a possibility of pooling at ground levels/pits.
• Silicon dioxide can be deposited using a combination of silicon precursor gasses like dichlorosilane or silane and oxygen precursors, such as oxygen and nitrous oxide, typically at pressures from a few millitorr to a few torr.
• Early studies of PbH revealed that the molecule is unstable as compared to its lighter congeners silane, germane, and stannane.
• So with the help of a workmate who had invented low pressure (LPCVD) polysilicon deposition at Motorola a few years earlier a low pressure silicon nitride system was built using silane and ammonia to produce the precisely tunable and uniform thicknesses needed at each of the bands.
• Silicone rubber–based pressure-sensitive adhesives require special tackifiers based on "MQ" silicate resins, composed of a monofunctional trimethyl silane ("M") reacted with quadrafunctional silicon tetrachloride ("Q").
• Treatment of that product with triethyl silane then reduces the ring unsaturation and cleaves the benzylic nitrogen bond on the auxiliary to yield as the optically pure trans isomer.
• Since then, a number of studies have firmly established the mechanism of electrophilic attack on vinyl- and allylsilanes The electron-releasing strength of the carbon-silicon bond is large, and as a result, the position of silicon in the unsaturated silane controls the site of reaction and stereoselectivity.
• Indeed, self-assembled layers of silanes on silicate surfaces have been reported to be dependent on various parameters such as humidity, temperature, impurities in the silane reagent and the type of silicate surface.
• A model for the Sakurai 1,2-addition, proposed by Kumada, is presented in the scheme below; the syn diastereomer is predominant when the (E) silane is used, and also slightly favored when the (Z) silane is used.
• The silane group attaches to the glass substrate via covalent Si-O-Si bond, while the resin reacts with the vinyl-, amino-, or epoxy- group and binds to it.
• Alternatively, the reaction of trimethylsilyl chloride and trichlorosilane in the presence of lithium delivers the silane directly but in modest yield:.
• Binary silicon-hydrogen compounds (which are sometimes called silanes also) includes silane itself but also compounds with Si-Si bonds including disilane and longer chains.
• Other method to form silanides are to heat a heavy metal silicide with hydrogen, or react the dissolved metal with silane.
• The produced silane triol can undergo further condensation, which results in either siloxane polymers or monomers depending on the concentration.
