Abstract

5890. Newton, P. A., [Farbenfabriken vorm. E. Bayer & Co.]. March 10. Dyes, artificial.-A new yellow dye-stuff, capable of forming a " vat " with alkaline reducing agents such as sodium hydrosulphite, is obtained by heating #-methylantbraquinone with sulphur. The melt is successively purified by means of aqueous sodium sulphide and by pyridine. The crystalline dye-stuff is insoluble in dilute acids and alkalies, and yields a violet solution with concentrated sulphuric acid.
