Process for distilling crude acrylic silane solution

摘要

A process for distilling a crude acrylic silane solution particularly containing impurities in a commercial scale for separating acrylic silane in the presence of a hindered phenol and/or amine as polymerization inhibitor is disclosed, the process is improved by using simultaneously a dialkyldithiocarbamic acid copper and/or N-nitrosophenylhydroxylamine salt as synergistic polymerization inhibitor.
