    摘要： A method of producing a halosiloxane, the method comprising: combining water, a halosilane, and a first solvent, where the first solvent has a water solubility of >1.5 grams in 100 ml of solvent, to form a reaction mixture having a temperature above the melting point temperature of the solvent, partially hydrolyzing and condensing the halosilane to form a reaction product mixture comprising the halosiloxane, the solvent, a hydrogen halide and unreacted halosilane, and, optionally, adding a second solvent with a boiling point≥the boiling point of the halosiloxane to the reaction mixture or the reaction product mixture.

    摘要： A component made of micromachinable material for a high quality factor resonator or escapement mechanism, with a core made of micromachinable material and/or coated with an oxide layer, and including, on this core or on this oxide layer an abrasion resistant layer including a contact surface cooperating with an opposing contact surface an which is a hydrophobic self-assembled monolayer of the alkylsilane and/or fluorinated or perfluorinated or polyperfluorinated type, with a low or zero sulphur content, and arranged to repel any wetting agent from the area of contact between the contact surface and the opposing contact surface.

    摘要： A method for converting organosilanes by reacting at least one silane (1) of the general formula RaSiCl4-a  (I) with at least one further silane (2) of the general formula RbSiCl4-b  (II) wherein silane (2) is identical or different from silane (1), optionally with additional use of silanes (3) which contain Si-bonded hydrogen and have the formula RdHeSiCl4-d-e  (III) in the presence of aluminum salts, preferably aluminum halides, as catalysts and in the presence of cocatalysts, to obtain at least one silane (4) which differs from silanes (1) and (2) and has the general formula RcSiCl4-c  (IV).

    摘要： A method of producing a halosiloxane, the method comprising: i) combining water, a halosilane, and a first solvent to form a reaction mixture, ii) partially hydrolyzing and condensing the halosilane to form a reaction product mixture comprising the halosiloxane, the solvent, unreacted halosilane, and hydrogen halide, iii) adding a second solvent, where the second solvent has a boiling point the boiling point of the halosiloxane, to the reaction mixture in i) or to the reaction product mixture in ii), and iv) recovering the halosiloxane from the reaction product mixture.
