Polysulfidation that enables high conversion rates with good selectivity, eliminates the use of solid alkali metal sulfide hydrates, and allows alkali metal hydroxides in sulfurized raw materials A process for producing organosilanes is provided. In a process for preparing an organosilane of general formula I by reaction of an (halogenorganyl) alkoxysilane of formula II with a hydrous alkali metal hydrogen sulfide, sulfur and alkali metal carbonate in an alcohol, comprising: In this method, the molar ratio of (halogenylorganyl) alkoxysilane of formula II to alkali metal hydrogen sulfide is 1: 0.40 to 1: 0.75, and the molar ratio of alkali metal hydrogen sulfide to alkali metal carbonate is Characterized by a ratio of 1: 0.5 to 1: 1.5.
