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： An (alkylhalo)silane is prepared by charging a reactor with a contact mass comprising metallic silicon powder and a copper catalyst and feeding a gas containing an alkyl halide into the reactor whereby the silane is formed by direct synthesis. The contact mass in the reactor during reaction consists of particles having a mean particle size of 5-150 .mu.m and containing 10-80% by weight of particles having a particle size of up to 30 .mu.m and 10-90% by weight of particles having a particle size of at least 90 .mu.m. The contact mass is well fluidized to ensure rapid and uniform reaction whereby the (alkylhalo)silane is prepared at high selectivity with a minimized elutriating loss of contact mass.

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.
