Abstract: Process for the preparation of chlorophosphazene mixtures having a high proportion of cyclic trimer and tetramer by preparing a dispersion of finely divided ammonium chloride in an amount sufficient to initiate the formation of chlorophosphazene, then, after heating the dispersion to reflux, co-feeding ammonia and a solution of phosphorus pentachloride in a suitable solvent at a rate such that no free PCl.sub.5 concentration is allowed to exist in the reaction mass, and then recovering the cyclic chlorophosphazene produced.

Abstract: An apparatus for the continuous collection of a time-weighted gas sample is disclosed. The apparatus inclues a gas reservoir and an openable and closeable gas flow assembly communicating with the reservoir which assembly allows gas to flow at a constant rate from the exterior of the reservoir to the interior of the reservoir when there is a sufficient gas pressure differential between the exterior and interior of the reservoir so that the passing gas achieves a linear velocity in the throat of the gas flow assembly equal to the velocity of sound in the passing gas in the throat. The apparatus of this invention may also include additional gas sample removal assemblies attached to the reservoir.
