ABSTRACT:
The present invention relates to mercaptoalkyl alkoxysilanes and the permanent removal of the odorants contained in these compounds. These odorants form during the preparation of the said mercaptosilanes from halogen alkylsilanes with thiourea and ammonia. The removal of the odorants is performed by the admixture of compounds which contain oxirane groups. A subsequent purification, e.g., by distillation, after the addition of these compounds in accordance with the invention, is not necessary. The additive used in accordance with the invention also brings about a sustaining of the freedom from odor for several months.
