Of potassium sulfide and sufficient water to make a thin paste. This paste, which was dark green in color, was poured into 200 cc. Of boiling water, and the mixture was boiled for about 1 hour. The amino compound was collected and washed thoroughly with boiling water. It was a brick-red powder, with a bronze-like luster. It crystallized from absolute alcohol in beautiful, long, bright red needles with a distinct greenish sheen. Yield, 2 g. ; m p. , 245-246; m. P. , (corr. ) 252-253. Analysis. S...ubs, 0. 3575: N, 19. 6 cc. (18, 756 mm. ). Calc. : N, 6. 28. Found: 6. 29. 1-Hydroxylamino-anthraquinone, by the Reduction of the Nitro Compound with Pyridine and Hydrogen Sulfide Two hundred cc. Of pyridine (technical) was placed in a 500cc. Erlenmeyer flask and saturated with dry hydrogen sulfide at 0. To the ice-cold solution, 8 g. Of very finely powdered 1-nitro-anthraquinone was added in small portions while the flask was shaken vigorously. The nitro compound dissolved quite readily, and was reduced to the hydroxylamino compound which formed a solution intensely red in color.
