Abstract

1 6 , 5 0 5. Badische Anilin & Soda Fabrik. Oct. 15,1906, [date applied for under Patents Act, 1901]. Samples furnished under Section 2 of Patents &c. Act, 1907. Dyes, artificial.-Vat colouring-matters are obtained by treating aminoanthraquinones with a metal, such as copper or aluminium, in presence of sulphuric acid. In examples, 1-aminoanthraquinone, 2-aminoanthraquinone, and the diaminoantbraquinone obtainable by reducing a-dinitroanthraquinone (German Specification, No. 72,685), are heated with sulphuric acid and copper powder. Specifications Nos. 3239, 12,185, 22,762, and 24,354, A.D. 1901, and No. 19,322, A.D. 1906, are referred to.
