ABSTRACT:
A process for the purification of hydrogen-containing silanes and siloxanes containing no phenyl substituent groups comprising contacting the silanes and siloxanes with an adsorbent bed formed from material selected from charcoal and molecular sieves and removing the purified silanes and siloxanes from the adsorbent bed. Through this procedure all the impurities which would poison the platinum catalyst are removed and as such the hydrosilanes and siloxanes will undergo SiH-olefin platinum-catalyzed reactions instantly and without difficulty.
