Not indexed. Not illustrated. 1864 Excerpt: . . . by basic acetate of lead; and the latter precipitate is pressed and decomposed under water by hydrosulphuric acid. The sulphide of lead is removed; the filtrate evaporated to a syrup over the water-bath; and the crystals which separate after 24 hours, are collected, washed with water, as long as the liquid which runs off exhibits a whitish turbidity, then with a small quantity of alcohol, and purified by recrystallisation (Salm-Horstmar). Properties. LTydrated fraxin forms tufts of needles, consisting of slender four-sided prisms, having a dazzling white colour, with a tinge of sulphur-yellow (Salm-Horstmar). From a hot saturated solution in absolute alcohol, it separates on cooling in colourless crystals, resembling those of sulphate of zinc, and not turning yellow when dry (Rochleder). Inodorous, lias a slightly bitter and astringent taste. In a very dilute aqueous or alcoholic solution, especially if it contains a trace of ammonia or fixed alkali, it exhibits by daylight a blue or (Salm-Horstmar, Stokes). Crystallised fraxin dried in vacuo at temperatures below 110, still bluish-green fluorescence, which of acids retains 1 at. water; that which has been dried between 110 and 113 contains no water (Rochleder). This formula alone--not the formula C42HK, 0J formerly proposed by Hochledor Cor CII-O26 by Wurtz (Sip. Chim. pure 1, 473)--agrees with the quantities of sugar obtained by the decomposition of fraxin. Decompositions. 1. Fraxin heated to 320, gives off water, and melts, to a red liquid, which solidifies on cooling, to an amorphous fissured mass, crumbling to a cream-coloured powder, probably fraxetin, when water is poured upon it, and dissolving with yellowish red Colour in alkaline water (Rochleder). On applying a stronger heat, it gives off an odou. . . This item ships from La Vergne,TN.<
