Between 218 and 220 the thermometer became stationary the fraction distilling at UGG boots sale that temperature solidified on cooling, and exhibited the boiling-poiot, fusing-point, and the other properties of naphthaline. The thermometer then rose rapidly to 290 , and the whole liquid had distilled before the thermometer reached 300 . The liquid distilling between 290 and 300 was of a light-yellow colour, and of a peculiar aromatic odour after standing for twenty-four hours in a cold room, it likewise solidified to a crystalline mass. On immersion in a frigorific mixture, solidification immediately took place once solidified, the compound no longer liquefied at the ordinary temperature. The new compound thus obtained is easily soluble in alcohol the crystals which on evaporation separate from this solution are absolutely pure.
On adding water to the alcoholic solution the body separates as an oil, which after a few moments solidifies to a confused mass of crystals. These crystals fuse at 33 5 fused and resolidified, the substance is heavier than Coach Outlet Store water its boiling-point is 296 -5 (corr.). The new compound represents in the naphthyl-series the benzonitrile in the benzoic Coach Factory Outlet series. Its composition, as has already been pointed out in the equation exhibiting its formation, is represented by the formula On dissolving the nitrile UGG boots online in an alcoholic solution of soda, comparatively little ammonia is disengaged but addition of water to the solution shows at once that the nitrile has undergone transformation. The crystals which arc precipitated are far less fusible and soluble than the nitrile.
By one or two recrystallizations from boiling alcohol they are obtained in a state of perfect purity. Thus prepared Coach outlet they are fine white needles, fusing at 244 (corr.), and subliming at a high temperature. Analysis has proved these crystals to have the composition CuH,NO = C H7N + EaO, thus showing that they are the amide corresponding to the nitrile, from which they are derived by the accession of 1 molecule of water.
I Ralph lauren australia have mentioned that the transformation of the nitrile into the amide is attended by an evolution of ammonia. This evolution is obviously due to the further change of the amide. Assimilating a second molecule of water, this substance gives rise to the formation Coach handbags new 2012 of UGG boots clearance an ammoniumsalt, C HaNO + H20 = C HnNOa = C H7 (H4N)02, which in its turn is converted into the sodium compound with evolution UGG boots outlet of ammonia. Indeed, on adding hydrochloric acid to the alkaline solution, an abundant precipitate of a beautifully crystalline acid is obtained, the properties of which strongly resemble Nike outlet store those of benzoic acid. It is scarcely necessary to state that the difficultly soluble amide, when submitted to the protracted action of boiling soda, is ultimately entirely converted into Coach Outlet Online the new acid.
