摘要： Anthraquinone derivatives.--1 : 4-Diphthalimidoanthraquinone is nitrated, the product hydrolysed and reduced and the amino derivative obtained, benzoylated. The product of nitration is substantially mono-nitro derivative, and the benzoyl derivative is a valuable vat dye, dyeing in bright red shades. According to examples, 1 : 4-diphthalimidoanthraquinone is nitrated in oleum with various quantities of nitric acid in excess of that required for mono-nitration, hydrolysis of the product is performed with sulphuric acid, the product is reduced with sodium sulphide and the reduced product benzoylated with benzoyl chloride or other benzoylating agent. The 1 : 4-diphthalimidoanthraquinone may be prepared by the action of phthalimide on 1 : 4-dihalogenanthraquinone or the anhydride on the 1 : 4-diamino compound. Specifications 2702/09 and 231,206, [both in Class 2 (iii), Dyes &c.], are referred to.

Addition to 276,767, Anthraquinone vat dyes.-The vat dyes obtained by alkali fusion of the sulphonic acids prepared by direct sulphonation of homologues or derivatives of benzanthrone are condensed with hydroxylamine or its salts in presence or absence of ferrous sulphate; and the vat dyes obtained by alkali fusion of the benzanthrone sulphonic acids prepared from anthraquinone sulphonic acids by the glycerine method are similarly treated. In examples, the dyes obtained from Bz1-chlor- and 2-methylbenzanthrones by sulphonation and alkali fusion, and from anthraquinone #.sulphonic acid by condensation with glycerine and alkali fusion of the Benzanthrone sulphonic acid obtained, are employed, giving grey-blue, grey and blue-grey dyes respectively.

摘要： 276,768. British Dyestuffs Corporation, Ltd., Baddiley, J., Shepherdson, A., and Thornley, S. June 21, 1926. Dibenzanthrone dyes.-The dyestuffs obtained by alkali fusion of benzanthrone sulphonation products, as described in Specification 276,766, are treated with alkylating agents, or first with oxidizing agents and then with alkylating agents; the oxidized products may be treated with reducing agents prior to alkylation. According to examples, (1) the alkali-fusion product of sulphonated benzanthrone (hydroxydibenzanthrone) is treated with dimethylsulphate in nitrobenzene; the methylation product dyes cotton in blue shades from the vat; (2) the same hydroxydibenzanthrone is oxidized with manganese dioxide in sulphuric acid, reduced by boiling with bisulphite solution, and methylated; the product dyes cotton in greenish-blue shades: the oxidation product and its reduced derivative also dye cotton, but the green shades so obtained are not fast to acid and alkali.

摘要： Benzanthrone derivatives containing selenium are made by the interaction of benzanthrone or its substitution products with selenium or a selenium compound. The products may be treated with acid or alkaline condensing agents, or nitrating (followed by reduction if desired), halogenating, sulphonating, or oxidizing agents, or they may be condensed with alkyl or aryl halides or subjected to heat treatment, further products being thereby obtained. In examples (1) benzanthrone is treated with selenium dioxide in sulphuric acid to give a product containing selenium; on alkali-fusion this gives a vat dye dyeing in blue shades; (2) Bz1 : Bz1 -dibenzanthronyl selenide is obtained by treating Bz1-chlorbenzanthrone (a) with selenium or selenium dioxide in tetrahydronaphthalene in presence of sodium acetate, or (b) with selenium and calcium hydroxide in methylated spirit, with or without a copper catalyst; other acid absorbers, e.g. quicklime, barium hydroxide, sodium phosphate or sodium acetate may be used instead of calcium hydroxide; (3) Bz1 : Bz1 -dibenzanthronyl selenide is treated with chlorine in nitrobenzene in presence of a trace of iodine; the product, according to one of the Provisional Specifications, is a mixture of benzanthrone and chlorbenzanthrone; (4) Bz1 : Bz1 -dibenzanthronyl selenide is brominated at room temperature; the product appears to be a dibromobenzanthrone; (5) Bz1 : Bz1 -dibenzanthronyl selenide on alkali-fusion, or on treatment with aluminium chloride in pyridine, yields isodibenzanthrone; (6) Bz1 : Bz1 -dibenzanthronyl selenide is oxidized with hydrogen peroxide in sulphuric acid; the product, on alkali-fusion, dyes in a similar shade to that given by isodibenzanthrone; (7) Bz1 : Bz1 -dibenzanthronyl selenide is nitrated in the presence or absence of sulphuric acid or in nitrobenzene; one of the products is a tetranitro derivative which, on alkali-fusion, gives a vat dye dyeing in grey shades; (8) Bz1 : Bz1 -dibenzanthronyl selenide is sulphonated; (9) Bz1-benzanthronyl hydrogen selenide is obtained by treating Bz1-chlorbenzanthrone with selenium and caustic soda in methylated spirit; on treatment with dimethyl sulphate or iodobenzene the corresponding methyl- and phenyl-selenides are obtained: the latter yields isodibenzanthrone on alkali-fusion; (10) Bz1 : Bz1 -dibenzanthronyl selenide is obtained from Bz1-benzanthronyl hydrogen selenide (a) by heating to 300 DEG C, (b) by heating with copper and nitrobenzene, (c) by heating with alcohol with addition of copper and lime, (d) by heating with selenious acid in nitrobenzene, or (e) by heating in sulphuric acid; (11) dichlorbenzanthrone (made by chlorinating Bz1-chlorbenzanthrone with sulphuryl chloride in nitrobenzene in presence of iodine) is treated with selenium to give a chlorinated dibenzanthronyl selenide, which, on alkali-fusion, gives a dye of the isodibenzanthrone type, and (12) nitro- and methoxy-Bz1-chlorbenzanthrones (examples (1) and (4) of Specification 256,281, [Class 2 (iii), Dyes &c.], on similar treatment yield amino-and methoxy-Bz1 : Bz1 -dibenzanthronyl selen ides, which also give dyes of the isodibenzanthrone type on alkali-fusion.

摘要： Benzanthrone derivatives.-The dyes obtained by treating benzanthrone or dibenzanthronyls or their substitution products with hydroxylamine or substances yielding hydroxylamine (such as potassium hydroxylamine mono- and di-sulphonates), followed by alkali fusion, are treated with alkylating or aralkylating agents; the products are usually faster than the original dyes. In examples (1) the product obtained from benzanthrone by sulphonation, treatment with hydroxylamine or potassium hydroxylamine disulphonate, and caustic potash fusion, is reduced with sodium bisulphite in sulphuric acid and methylated with dimethylsulphate in nitrobenzene; the product dyes cotton in bluish-grey shades, (2) the products of examples 1, 2, and 3 of Specification 348,159, are treated with dimethylsulphate to yield products dyeing in blue to grey shades, (3) the parent material used in example 1 is benzylated by means of benzyl chloride; the product dyes in grey-blue shades, (4) the product obtained by sulphonating chlorinated Bzl : Bzl1-bibenzanthronyl (containing 16,7 per cent chlorine), treating with hydroxylamine hydrochloride and alkali fusion is methylated with dimethylsulphate; the product dyes in blue-grey shades, (5) the product obtained by treating chlorinated 2 : 21-dibenzanthronyl (containing 16 per cent chlorine) with potassium hydroxylamine disulphonate and alkali fusion is methylated with dimethylsulphate; the product dyes in blue-grey shades, and (6) the product obtained by sulphonating Bzl-chlorbenzanthrone, treating with hydroxylamine hydrochloride and alkali fusion is methylated with dimethylsulphate; the product dyes in violet shades.

摘要： 282,913. British Dyestuffs Corporation, Ltd., Shepherdson, A., and Thornley, S. Oct. 8, 1926. Pyranthrone derivatives.-Pyranthrone, or a derivative such as chlor- or brom-pyranthrone, is treated with hydroxylamine in the presence of sulphuric acid and in the presence or absene of ferrous sulphate. The products dye cotton from the vat in brown shades which are fast to chlorine; by acylation they are converted into other products, which can be purified by means of hypochlorites, and which dye cotton from the vat in fast brown shades. According to examples, pyranthrone is treated with hydroxylamine hydrochloride in sulphuric acid containing ferrous sulphate and the product benzoylated with benzoyl chloride in nitrobenzene; it is then boiled with sodium hypochlorite with addition of acetic acid. Other acylating agents specified are acetic anhydride acetyl chloride, oxalyl chloride, and anisoyl chloride. Specification 282,852 is referred to.
