Uses

Used in Surface Coating Applications:
N-BUTYLTRICHLOROSILANE is used as a coating agent for glass substrates to introduce surface alkyl, which can bind well with 2-methacryloyloxyethyl-4-azidobenzoate (MPAz). This conversion process transforms hydrophopic glass surfaces into superhydrophilic surfaces, enhancing their properties for various applications.
Used in Sensor Technology:
In the sensor industry, N-BUTYLTRICHLOROSILANE is used to functionalize zinc peroxide nanoparticle/polystyrene sulfonate (PSS) hybrid-based sensors. Its application improves the limit of detection by three-folds, making it a valuable component in enhancing sensor performance and accuracy.
Used in Silicon Compound Production:
N-BUTYLTRICHLOROSILANE is utilized as a key component in the production of various silicon-containing compounds. Its role in this industry is crucial for the development and manufacturing of a wide range of products that rely on silicon-based materials.

Reactivity Profile

N-BUTYLTRICHLOROSILANE reacts with water, moist air, or steam to produce heat and toxic, corrosive fumes of hydrogen chloride and flammable butane. Can serve as a chlorination agent. Reacts vigorously with both organic and inorganic acids and with bases to generate toxic or flammable gases. Reacts with alcohols, acetone and light metals.

Health Hazard

Inhalation of vapor irritates upper respiratory system. Contact of liquid with eyes or skin causes severe burns. Ingestion causes burns of mouth and stomach.

Safety Profile

A corrosive poison. See also CHLOROSILANE. Flammable liquid when exposed to heat, flame (sparks), or oxidizers. To fight fire, use water to blanket fire, fog, mist, dry chemical, alcohol foam.

PROCESS FOR THE STEPWISE SYNTHESIS OF SILAHYDROCARBONS

The invention relates to a process for the stepwise synthesis of silahydrocarbons bearing up to four different organyl substituents at the silicon atom, wherein the process includes at least one step a) of producing a bifunctional hydridochlorosilane by a redistribution reaction, selective chlorination of hydridosilanes with an ether/HCI reagent, or by selective chlorination of hydridosilanes with SiCI4, at least one step b) of submitting a bifunctional hydridochloromonosilane to a hydrosilylation reaction, at least one step c) of hydrogenation of a chloromonosilane, and a step d) in which a silahydrocarbon compound is obtained in a hydrosilylation reaction.

Chiral cyclotrisiloxanes

We have synthesized and separated the enantiomer pair of chiral cyclotrisiloxanes for the first time. Three-blade propeller-like alignment of three phenyl groups in tri(2-butyl)triphenylcyclotrisiloxane induced a positive Cotton effect with (R)-2-butyl group, and a negative effect with (S)-2-butyl substituent.

Direct synthesis of organodichlorosilanes by the reaction of metallic silicon, hydrogen chloride and alkene/alkyne and by the reaction of metallic silicon and alkyl chloride

Dichloroethylsilane was synthesized by the reaction of metallic silicon, hydrogen chloride and ethylene using copper(I) chloride as the catalyst, the silicon conversion and the selectivity for dichloroethylsilane being 36 and 47%, respectively. At a lower reaction temperature or at a higher ratio of ethylene: hydrogen chloride a higher selectivity was obtained, however the silicon conversion was lower. The silicon-carbon bond formation is caused by the reaction of a surface silylene intermediate with ethylene. The reaction with propylene in place of ethylene gave dichloroisopropylsilane (22% selectivity) and dichloro-n-propyl-silane (8% selectivity) together with chlorosilanes. A part of the dichloroisopropylsilane is formed by the reaction of silicon, hydrogen chloride and isopropyl chloride formed by hydrochlorination of propylene. Use of acetylene instead of alkenes resulted in dichlorovinylsilane formation with a 34% selectivity. Alkyldichlorosilanes were also produced directly from silicon with alkyl chlorides, propyl and butyl chlorides. During the reaction the alkyl chloride is dehydrochlorinated over the surface of copper originating from the catalyst to afford hydrogen chloride and alkene. The hydrogen chloride formed participates in the formation of the silicon-hydrogen bond in alkyldichlorosilane, and the reaction of silicon, hydrogen chloride and alkene also causes alkyldichlorosilane formation. The reaction with isopropyl chloride gave a very high selectivity (85%) for dichloroisopropylsilane, the silicon conversion being 86%. The Royal Society of Chemistry 2001.
