Versuchsvorschrift

The starting octamethylcyclotetrasilazane should effectively be one which is secondarily produced when hexamethylcyclotrisilazane is prepared by reaction between dimethyl dichlorosilane and ammonia. Using such secondarily produced octamethylcyclotetra-silazane, the amount of hexamethylcyclo-trisilazane formed per unit starting material can be maximized. At the same time, some technical problems can be solved including elimination or treatment of octamethylcyclo-tetrasilazane in the form of a solid (melting point of 97° C.) which is left in the distillation column after removal of hexamethylcyclo-trisilazane by distillation.
