<p>Cyclotrisilazanes, including hexamethylcyclotri- sflazane, a difunctional blocking agent used to derivatize and protect active hydrogencontaining substrates during chemical analysis and synthetic reactions, may be prepared by heating cyclotetrasilazanes using a Group VIII catalyst in the presence of hydrogen. In addition, the average degree of polymerization of cyclosilazane compositions may be reduced.</p> |
