Abstract

5 - Nitro - 1 - aminoanthraquinone - 2 - carbonyl chloride is made by reacting 5-nitro-1-aminoanthraquinone-2-carboxylic acid with thionyl chloride in nitrobenzene at 85 DEG C., cooling the mixture and filtering off the product. Specification 267,164, [Class 2 (3)], is referred to.ALSO:The invention comprises red dyes of the formula <FORM:0809043/IV (c)/1> where n is 1, 2 or 3 and R is hydrogen or alkyl, and a process for making them either by heating 5-nitro-1-aminoanthraquinone-2-carboxylic acid with an alcohol of the formula H(OCH2CH2)nOR or by treating the corresponding acid chloride with such an alcohol. Excess alcohol may be present, and sulphuric acid or hydrogen chloride may be used to catalyse the reaction between the acid and alcohol. Alcohols which may be used are 1 : 2-di-(b -hydroxyethoxy)-ethane, B : B1 - dihydroxydiethylether, diethyleneglycol monoethylether, ethylene glycol, ethyleneglycol monobutylether and diethyleneglycol monomethyl ether. Examples are given. The dyestuffs may be used for dyeing acetate rayon and polyethylene terephthalate, and may be dispersed by milling with sodium methylene bis-(naphthalene-2-sulphonate) to form an aqueous paste, which may be dried, if desired, to form a re-dispersible powder. Specification 267,164, [Class 2 (3)], is referred to.
