The preparation of high-purity organosilicon disulphanes in which, in a two-stage process, elemental sulphur and an anhydrous alkali sulphide in a deficient amount is first reacted with a halogen alkylalkoxysilane, and the sulphur deficit is then made up by the addition of further alkali sulphide.

Préparation en deux étapes de disulphanes organosiliciés de grande pureté, consistant à faire réagir d'abord du soufre élémentaire et un sulfure d'alcali anhydre en quantité déficitaire avec un alkylalcoxysilane halogéné; le déficit en sulfure est ensuite comblé par addition de sulfure d'alcali supplémentaire.
