Preparation of cycloorganotrisilazanes.

摘要

What is disclosed is a process for the rearrangement of cylcoorganopolysilazanes to cycloorganotrisilazanes using quaternary ammonium halides as a catalyst. The quaternary ammonium halide has the formula R<i>4NX where at least one R<i> is a group containing greater than 11 carbon atoms and X is a halogen atom. The rearrangement process is ran either as a batch or a continuous distillation procedure.
