PROCESS FOR PREPARING ORGANOSILANES

The invention provides a process for preparing organosilanes of the general formula (I) wherein a) (haloorganyl)alkoxysilane of the formula (II) is reacted with a sulphurising reagent selected from the group of alkali metal hydrogensulphide, metal sulphide M2S, metal polysulphide M2Sg and any desire...

More Information
Summary:The invention provides a process for preparing organosilanes of the general formula (I) wherein a) (haloorganyl)alkoxysilane of the formula (II) is reacted with a sulphurising reagent selected from the group of alkali metal hydrogensulphide, metal sulphide M2S, metal polysulphide M2Sg and any desired combinations thereof and optionally additionally with sulphur and/or with H2S in an organic solvent, b1) subsequently, the organic solvent is removed from the suspension which forms, and the liquid phase comprising the organosilane of the formula (I), and the solid phase comprising MX and residual organosilane of the formula (I), are separated from the remaining suspension, or b2) subsequently, the liquid phase comprising the organosilane of the formula (I) and the organic solvent, and the solid phase comprising MX and residual organosilane of the formula (I), are separated from the suspension which forms, and the organic solvent is removed from the liquid phase, c) the solid phase comprising MX and residual organosilane of the formula (I) is mixed with water and d) the organic phase which forms, comprising the organosilane of the general formula (I), is removed.
