A process for the preparation of a sulfidosilane comprising reacting an aqueous phase comprising a sulfide compound, which is a polysulfide of the formula M2Sx and/or a mixture of sulfur with a hydrosulfide of the formula MHS or a sulfide of the formula M2Sn, where M represents ammonium or an alkali metal, x is defined as above and n has an average value of 1 to 10, with a silane mixture of an alkoxydialkylhaloalkylsilane of the formula (R′O)R2Si-A-Z and a hydroxydialkylhaloalkylsilane of the formula (HO)R2Si-A-Z, where each R is selected from alkyl or aryl groups having 1 to 18 carbon atoms, each A independently represents the same or different divalent organic group having 1 to 18 carbon atoms, R′ represents an alkyl group having 1 to 8 carbon atoms and Z represents a halogen selected from chlorine, bromine and iodine. |
