Abstract

338,217. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). July 6, 1929. Halogenated anthraquinone-2-1-benzacridones. -4.Bz2.3.4.5-Pentahalogenanthraquinone - 2.1 - benzacridones are prepared by condensing 1.4-dihalogenanthraquinone-2-carboxylic acids or their esters with tetrahalogenanilines having a free oposition to the amino group, acridone ring closure then being effected according to known, methods. Or the same bodies may be obtained by treating anthraquinone-2-1-benzacridones containing halogen at least in the Bz2- and Bz4- positions with halogenating agents in the presence of an organic solvent. When starting from products having the 4- position free only chlorinating agents are to be employed since bromine only enters this latter position in small amounts. In examples (1) 1.4-dichloranthraquinone-2-carboxylic acid benzyl' ester is condensed with 2.3.4.5-tetrachloroaniline, the product saponified and ring- closed; (2) Bz2.3.4.5-tetrachloranthraquinone-2.1. benzacridone (prepared according to Specification 338,216) is treated in nitrobenzene and in presence of iodine with sulphuryl chloride; (3) 4.Bz2.4 - trichloranthraquinone-2.1-benzacridone (prepared by condensing 1.4-dichloranthraquinone-2-carboxylic acid with 3.5-dichloraniline and ring-closure of the product) and Bz2.4-dichloranthraquinone-2.1-benzacridone (prepared according to Specification 338,216) are chlorinated as in (2). The halogenation of 4.Bz2-3-4- and 4.Bz2.4.5-tetrahalogenanthraquinone-2 - 1 - benzacridones (prepared by condensation of 1-4-dihalogenanthraquinone-2-carboxylic acid with 3.4.5- trihalogenaniline and 2.3.5-trihalogenaniline respectively, followed by ring-closure) is also mentioned. These products dye fast red shades which are distinguished by their high brilliancy; the pentachloro derivative also differs from those obtainable according to Specifications 5534/13 and 295,770 by being converted when boiled with diethylaniline into an orange-dyeing tetrachloro derivative from which the original pentachloro derivative is re-obtained by chlorination in organic solvents. Specifications 894/11 and 327,758 also are referred to.
