Abstract
1311742 Preparing the anthraquinone dyestuffs MITSUBISHI CHEMICAL INDUSTRIES Ltd 20 May 1970 [21 May 1969 9 June 1969 16 June 1969 17 June 1969] 24367/70 Heading CP4 Blue anthraquinone dyestuffs having the general formula wherein one X<SP>1</SP> is OH and the other -NH 2 , X is halogen and n is 0 to 2À0 are prepared b nitration and hydrolysis in any order of com pounds of the general formula where R is alkyl or phenyl optionally substituted by alkyl, alkoxy, or OH and one X 4 is H and the other OR, or by nitration of the above compounds when R is H, the 2-chloro-dihydroxy-dinitro anthraquinones thus prepared being subjected to reduction or to reduction and halogenation in any order. The compounds of the general formula II shown above are stated to be novel and are prepared by alkoxylation or phenoxylation of 2-chloro-1,5-(or 1,8-)dinitroanthraquinones. The dyes are used as disperse dyes on polyester, polyamide and cellulose ester fibres.
