XXVII.—On chlorophosphuret of nitrogen, and its products of decomposition

Abstract

The general result was to confirm the formula P3N,C15 assigned to chlorophosphuret of nitrogen by its discoverers, T;lrohler and Liebig, to describe the substance more fully, and especially t o show that, under the influence of aqueous ether, alkalies, and even of water] it was capable of' giving rise to two new acids, named respectively deutazophosphork an6 azophosphoric acids. The first was believed to be produced by the simple decomposition : Y3N,CI, + 8HO* = 3HO.P3N,O, + 5HC1; but neither the acid nor its salts could he obtained in a state to give trustworthy analyses. The second-azophosphoric acid-is produced from a solution of a deutazophosphate by heating it with different metallic salts, when a precipitate containing the new acid falls. The most remarkable of these is a ferric salt, insoluble in dilute acids, and soluble in ammonia; but several others were prepared, described, and analysed, and the common formula found for them was 3hf0.P2N0,, conbined with from two to five equivalents of water.
