Title: The manufacture of new anthraquinone derivatives
Filed: 1925-12-08
Abstract: Anthraquinone derivatives, some of which are vat dyestuffs, are obtained by treating with oxidizing agents the stable condensation products of formaldehyde and 4-substituted-1-aminoanthraquinones described in Specification 244,462; either the condensation products of Series I or those of Series II may be used, but in the latter case a greater quantity of oxidizing agent is required and one molecule of formaldehyde is eliminated.  The oxidation may be effected in sulphuric acid solution with manganese or lead dioxide, if desired, with an addition of boric acid; concentrated or fuming sulphuric acid alone may also be used, advantageously with an addition of an oxygen carrier such as mercuric oxide or selenious acid.  The compounds are of the nature of quinones and yield with reducing agents reduced compounds which are easily oxidized again; either the reduced or the unreduced compounds are applicable as dyestuffs.  Examples are given of the oxidation of both the Series I and the Series II compounds obtained from 1 : 4-amino-oxyanthraquinone and formaldehyde by means of manganese dioxide in sulphuric acid of different strengths, with or without boric acid, and by means of concentrated sulphuric acid alone; the reduction product is obtained by pouring the reaction product into water containing sulphurous acid or bisulphite; it dyes cotton from the hydrosulphite vat in fast greenish-blue shades. Similar products are obtainable from the condensation products of formaldehyde with 1 : 4-diaminoanthraquinone or 1 : 4-aminomethoxyanthraquinone.  The Specification as open to inspection under Sect. 91 (3) (a) extends to the oxidation of condensation products from formaldehyde and 1-aminoanthraquinone or its derivatives generally.  This subject-matter does not appear in the Specification as accepted.
