The invention relates to a process for treating a composition comprising organosilanes and at least one polar organic compound and/or at least one extraneous metal and/or a compound containing extraneous metal, wherein the composition is contacted with at least one adsorbent and a composition in which the content of the organic polar compound and/or of the extraneous metal and/or of the compound containing extraneous metal is reduced is subsequently obtained, and also to a corresponding composition in which the content of polar organic compounds and/or extraneous metals has been reduced to traces, and to the use of organic resins, activated carbons, silicates and/or zeolites for reducing the amounts of the compounds mentioned.
L'invention concerne un procédé utilisé pour traiter une composition contenant des organosilanes, ainsi qu'au moins un composé organique polaire et/ou au moins un métal exogène et/ou un composé contenant un métal exogène. Ladite composition est mise en contact avec au moins un agent adsorbant et la teneur en composé organique polaire et/ou en métal exogène et/ou en composé contenant un métal exogène de la composition ensuite obtenue est réduite. L'invention concerne également une composition correspondante dans laquelle la teneur en composés organiques polaires et/ou en métaux exogènes est réduite à l'état de traces, ainsi que l'utilisation de résines organiques, charbons actifs, silicates et/ou zéolites pour réduire lesdits composés.
