phosphan11Ine

[Pref. phosph-, and Eng. aniline.] Chem. (C18H18P) N3. This body has not yet been isolated, but its hydrochloride is formed by the direct combination of aniline and phosphorus trichloride, thus: 3C6H7N+PC18=C18H18PN33HCl. It crystallizes in needle-shaped crystals. phos-phăn-ti-mon-Ic, a . [Pref. phosph- , and English antimonic .] Derived from or containing phosphoric and antimonic acids. phosphantimonic-acid, s . Chem.: An acid obtained by dropping antimonic pent a chloride into aqueous phosphoric acid. It precipitates morphine, narcotine, nicotine, and other alkaloids. Its true composition is unknown. phos-phar-sō-ni-ŭm, s . [Pref. phosph- , Eng. ars ( enic ), and ( amm ) onium .] mHP Org.

Geol.: A loose bed of brown nodules, first observed by Profe or Henslow at the foot of the Red Crag. They contain a large percentage of earthy phosphates, there being occasionally as much as sixty per cent. of phosphate hence they are much used for manure. Formerly they were considered to be coprolites. Remains of Mastodon arvernensis, M. tapiroides, Elephas meridional is , Hyæna antiqua , those of whales, a walrus, ., oc cur. There is a similar bed at the base of the Older White Crag at Sutton, England. ( Lyell .) phosphate of soda, s. 1. Chem.: PO(NaO)2HO+12H2O. Orthophosphate Common tribasic phosphate. Prepared by treating bone ash with sulphuric acid, and then adding carbonate of soda in slight exce to the acid filtrate. On evaporation the phosphate of soda crystallizes in oblique rhombic prisms, which di olve in four parts of cold water. It is bitter, purgative, and alkaline to test paper. NaPO3=metaphosphate of soda. Monobasic phosphate. Formed by the action of heat on acid tribasic phosphate, or microcosmic salt. It is obtained as a transparent, gla y substance, very soluble in water. Na2P207=pyrophosphate of soda. Bibasic phosphate. "Obtained by strongly heating common phosphate of soda. The residue is di olved in water and recrystallized. It forms brilliant crystals, which are le soluble than the original phosphate. The meta and pyrophosphates can be again converted into orthophosphates by fusion with exce of carbonate of soda. 2.
