Abstract

Bz-1-bromo-Bz-2-methyl-, methyl- or -isopropylbenzanthrone and Bz-1-chloro-Bz-2-isopropyl- or -n-pentyl-benzanthrone are made by brominating or chlorinating the corresponding Bz-2-alkylbenzanthrones. The bromination and chlorination may be conducted using bromine and sulphuryl chloride in chloroform or sulphuryl chloride in chlorbenzene respectively. Bz-2-isopropyl- or -n-pentyl-benzanthrone is made by condensing anthrone with alphaisopropyl- or alpha-n-pentyl-acrolein respectively. The condensation may be conducted in sulphuric acid in the presence of an oxidising agent.ALSO:The invention comprises vat dyestuffs of the formula: <FORM:0852517/IV (c)/1> where R is alkyl or aryl and R1 is amino or acylamino, and a process for making them by reacting a Bz-1-halogen-benzanthrone substituted by an alkyl or aryl group in the Bz-2-position with a 1 : 5- diaminoanthrquinone or an N-monoacyl compound thereof to give a compound of the formula: p <FORM:0852517/IV (c)/2> which is then melted with an alkaline condensing agent, such as alcoholic caustic potash, and reacting the product, if desired, with an acylating agent such as benzoyl chloride, m- or pchloro-, o- or mfluoro-, or methoxybenzoyl chloride, o-, m- or ptoluyl chloride, a - or b - naphthoyl chloride or 1 - aminoanthraquinone - 2 - carboxylic acid chloride. Hydrolysis of the acylamino group to form an amino group when using alcoholic potassium hydroxide in the melting step can be avoided if desired by melting the benzanthronylamino-5-acylaminoanthraquinone with an alkaline condensing agent substantially free from hydroxyl groups, such as sodium anilide or a sodium alcoholate, in aniline at about 140 DEG -170 DEG C. In examples (1), Bz - 1 - bromo -Bz -2- ethylbenzanthrone is reacted with 1-amino -5- benzoylaminoanthraquinone in nitrobenzene with copper powder and sodium carbonate to give Bz -2- ethyl- Bz -1- benzanthronyl -1- amino -5- benzoylaminoanthraquinone which is melted with caustic potash and monethanolamine, the leuco compound thus obtained being oxidized with air to give a vat dyestuff which dyes cotton grey, and (2) this dyestuff is treated with m-fluorobenzoyl chloride in chlorobenzene to give a khaki cotton dye from a blue vat; in further examples, vat dyes dyeing vegetable fibres or artificial silk grey, khaki, brown and olive shades are made in a similar manner from 1- amino-5-benzoylamineanthraquinone and Bz -1- bromo- or Bz -1- chloro- Bz-2- hydrocarbonbenzanthrones, the hydrocarbon radicals being selected from methyl, ethyl, isopropyl, n-pentyl and phenyl, and the dyes being acylated with benzoyl, mfluoro-, mchloro- or mmethoxybenzoyl chlorides or 1- aminoanthraquinone -2- carboxylic acid chloride. Specification 339,369 is referred to.
