摘要： Methyl chloride is prepared by effecting liquid-phase reaction between hydrogen chloride and methanol in the absence of a catalyst. The reaction is effected in divided stages including at least an early stage and a last stage. The early stage of reaction is effected in a stoichiometric excess of hydrogen chloride. The last stage of reaction is effected in a stoichiometric excess of methanol. The invention is industrially advantageous in that methyl chloride can be prepared at a high conversion of hydrogen chloride while suppressing the formation of dimethyl ether by-product.

摘要： A diorganodichlorosilane is prepared by subjecting organochlorosilanes to disproportionation reaction in the co-presence of a SiH group-containing compound and in the presence of a primary catalyst of AlCl3 or AlBr3 and a co-catalyst of Mg, Al, Ca, Ti, Fe, Ni, Cu, Zn or Sn or a compound thereof. The invention enables disproportionation reaction of organochlorosilanes under atmospheric pressure and at a low temperature at which no substantial sublimation of AlCl3 or the like occurs, thus allowing the reaction equipment to be simple and improving the safety of reaction.

摘要： For the continuous hydrolysis of organochlorosilane, a reaction system comprising at least three stages of hydrolysis is used. Each stage includes a reactor and a phase separator wherein hydrolysis is effected to form a hydrolysis mixture which is separated into a hydrolyzate and a hydrogen chloride-containing aqueous medium. The separated aqueous medium is circulated to the reactor. The hydrolyzate is conveyed to the reactor of the subsequent stage. The organochlorosilane is fed into the first stage reactor, the aqueous medium containing an amount of water corresponding to the consumption in one stage is fed into one stage reactor from the subsequent stage, and an amount of water corresponding to the consumption in the overall reaction system is fed in the last stage. Then the entire amount of hydrogen chloride generated in multiple stages of hydrolysis is recovered as anhydrous hydrogen chloride from the first stage. The entire amount of the aqueous media separated in the phase separators is retained in the reaction system.

摘要： An (alkylhalo)silane is prepared by using a fluidized bed reactor equipped with a feed line for reactant gas and a delivery line for product gas, charging the reactor with a contact mass comprising metallic silicon powder and a copper catalyst, and feeding a reactant gas containing an alkyl halide through the feed line into the reactor whereby the silane is formed by direct synthesis. A dust collector is connected to the delivery line for collecting the contact mass carried over with the product gas, which is fed back to the reactor. The feed of the reactant gas is controlled such that a linear velocity multiplied by a density may range from 0.2-2 kg/m.sup.2 .multidot.sec.

摘要： Alkylhalosilanes are produced by first fluidizing a metallic silicon powder with an inert gas, preheating the silicon powder at a temperature between 200.degree. C. and a steady reaction temperature while keeping the silicon powder fluidized, adding a copper catalyst to the preheated silicon powder to form a contact mass, and feeding an alkyl halide into the contact mass whereby the alkylhalosilanes are formed by direct synthesis. This process prevents the copper catalyst from being sintered by thermal hysteresis and activates a high catalysis on the contact mass at the start of reaction. The desired dialkyldihalosilane can be produced at a high selectivity.

摘要： An alkylhalosilane is prepared by charging a reactor with a contact mass comprising a metallic silicon powder and a copper catalyst, and feeding an alkyl halide into the reactor whereby the silane is formed by direct synthesis. The contact mass contains 1-10,000 ppm of elemental boron. The addition of boron to the contact mass is effective for increasing the throughput of dialkyldihalosilane at desired STY in an inexpensive manner while suppressing formation of unnecessary hydrosilanes and disilanes.

摘要： The direct synthesis of methylchlorosilanes to react metallic silicon with methyl chloride in the presence of a copper catalyst yields a high-boiling fraction of methylchlorodisilanes as by-products. The invention provides a method for preparing monosilanes from the high-boiling fraction by reacting it with hydrogen chloride in the presence of an amine or amide catalyst. The reaction is effected under the condition that the amount of iron, aluminum, zinc, tin and compounds thereof present in the reaction system is less than the equimolar amount with respect to the catalyst. This increases the conversion of disilanes into monosilanes.
