    Abstract: Phosphonitrilic chlorides having the general formula: PNCl2)n where n denotes an integer of at least 3 and which contain a high proportion of trimeric and tetrameric cyclic phosphonitrilic chlorides are prepared by reaction of phosphorus pentachloride with ammonia in an inert solvent. The solution should contain not more than 5 moles of phosphorus pentachloride per liter. Ammonia is introduced at a rate not exceeding 0.12 liter per minute per mole of the phosphorus pentachloride contained in the whole solution until one tenth to one third of the total amount of ammonia required has been introduced.
