Beschreibung
Zusammenfassung:	This invention is directed to an improved process for the preparation of condensable, film-forming organosilazanes by ammonolysis of organohalosilanes with liquid ammonia, the improvement comprising reacting a from about 5 to 15% by weight solution of organohalosilane in inert solvent with excess liquid ammonia under pressure at temperatures between 0 DEG and 50 DEG C.
