9 Colouration of materials made of or containing cellulose esters or ethers GB41331 1931-01-05 GB374839A 1932-06-06
Cellulose esters or ethers, dyeing; vat dyes, dyeing with; printing.--Cellulose ester or ether materials, whether alone or in admixture with other fibres, are dyed, printed, stencilled, or otherwise coloured with dyestuffs containing a single anthraquinone nucleus linked to a second cyclic residue through a heterocyclic grouping. Suitable dyestuffs are the anthraquinonexanthones, -acridones, -thioxanthones, -oxazines, -azines, -thiazines, -dioxides, -carbazoles, and -thiazoles which may be substituted in the anthraquinone residue and/or the aryl residue or residues, e.g. by amino, alkylamino, oxyalkylamino, acylamino, alkyl, hydroxy, or alkoxy groups, or by halogen atoms. The dyestuffs may be applied by any convenient methods, e.g. (1) from vats containing hydrosulphite or other reducing agent and ammonia or an organic base such as methylamine, ethylamine, propylamine, mono-, di-, or triethanolamine, cyclohexylamine, pyridine, or piperidine; (2) as aqueous suspensions or dispersions such as are obtainable by the processes described in Specifications 219,349, 224,925, 242,393, 242,711, 269,960, 273,819, 273,820, 322,737, and 323,788, [all in Class 2 (iii), Dyes &c.]. The dyestuffs may also be used to produce coloured discharges, e.g. by the process of Specification 351,457. The following examples are specified. (1) A cellulose acetate knit fabric is dyed orange-yellow by vatting at temperatures rising to 75 DEG C. in an aqueous liquor containing the dyestuff 3<1> : 4<1> - dichlor - 1 : 2 - anthraquinonethioxanthone, turkey red oil, sodium hydrosulphite, and methylamine, and thereafter oxidizing in a bath containing sodium perborate and soap. (2) A cellulose acetate woven fabric is dyed reddish violet by vatting at temperatures rising to 80 DEG C. in an aqueous liquor containing the dyestuff 1 : 2 : 5 : 6-anthraquinone-diacridone, monopol soap, sodium hydrosulphite, and mono-ethanolamine, and thereafter oxidizing in a bath containing hydrogen peroxide and soap. (3) Cellulose acetate yarn is dyed pink by treatment at 75-80 DEG C. in an aqueous bath containing the dyestuff 1 : 2-anthraquinone-acridone dispersed with pyridine and turkey red oil. The following additional dyestuffs are specified, viz. 3<1> : 4<1>-dichlor-1(NH) : 2(CO)-anthraquinone - acridone, anthraquinone - 1(NH) : 2(CO) - 2<1> : 1<1> - naphthacridone and 2<1> : 5<1>-dichlor-1 : 2-anthraquinone-thioxanthone. The use of the processes of Specifications 262,506, 263,473, [both in Class 15 (ii), Dyeing, Processes &c. for], and 341,408, and the use of anthraquinone-naphthacridones obtained by replacing one or more halogens in a 5 : 8 - dihalogenanthraquinone - 2 : 1(b )-naphthacridone by amino, alkylamino, or acyclic or monocyclic acylamino or acylimino groups are disclaimed. Specifications 197,281, 227,183, 284,376, and 285,104, [all in Class 15 (ii), Dyeing, Processes &c. for], also are referred to. The Provisional Specification describes also the use of dyestuffs in general in which two adjacent carbon atoms of an anthraquinone residue form part of a carbocyclic or heterocyclic ring, and specifies the use of 1 : 2 - benzanthraquinone, 1 - oxy - 2 : 3 - benzanthraquinone, anthraquinone-quinolines, and anthraquinone-thiazines such as 1 : 2-anthraquinone-keto-dihydrothiazine.

PURPOSE:To obtain a vat dye of good quality in a high yield, by chlorinating a specified condensation product obtd. by a reaction in the presence of 1,3-dimethyl-2-imidazolidinone. CONSTITUTION:0.1-10pts.wt. alkaline condensing agent such as KOH and optionally a wetting agent such as an alkali metal naphthalenesulfonate are added to one pt. 1-aminoanthraquinone in the form of a powder or a slurry while introducing an oxidizing agent such as air. A condensation reaction is conducted in the presence of 0.1-10pts.wt. 1,3-dimethyl-2-imidazolidinone at 80-150 deg.C to obtain a condensation reaction product. The product is slurried in water and reduced with hydrotalcite in the presence of an alkali metal hydroxide. The resulting crystal is recovered by filtration and slurried in water. The resulting dianthraquinone-N,N-dihydroamine or the above product is chlorinated in sulfuric acid. The product is recovered by filtration and the filter cake is completely dissolved in 98% sulfuric acid and reduced with Al powder to obtain a vat dye of the formula, wherein n is 1, 2.

Chorinated indanthrones are obtained by heating b -aminoanthraquinone with antimony pentachloride and selenium or a selenium chloride in nitrobenzene with, if desired a copper catalyst. The formation of flavanthrone in this reaction is prevented or hindered. According to examples, the reaction is performed in presence of selenium, and selenium with varying small quantities of copper acetate at temperatures of 120 to 170 DEG C.
