摘要:1,1'-Binaphthyl-4,4',5,5',8,8'-hexacarboxylic acid compounds having the following formula: ##STR1## wherein R 1 is hydrogen, halogen, or alkyl; when X is oxygen, Y is hydrogen, alkyl, a cycloalkyl, or an aryl containing at least one substituent from the group including: halogen, alkyl, or alkoxy, when X is nitrogen, Y is ##STR2## wherein R 2 is hydrogen, halogen, or alkyl; Y being linked to X with the formation of a benzimidazole cycle. n The method for preparing the compounds according to the present invention resides in the treatment of that 1,1'-binaphthyl-4,4',5,5',8,8'-hexacarboxylic acid anhydride with an alkali to give a corresponding salt which is condensed with orthophenylenediamines upon heating at reflux at a pH of from 6.3 to 6.8. The resulting benzimidazole-1,1'-binaphthyl-4,4',5,5',8,8'-hexacarboxylic acid anhydride having the formula: ##STR3## wherein R 1 is hydrogen, halogen, or alkyl, is isolated and condensed with an amine or ortho-phenylenediamines in an excess of the amine, in water or an organic solvent, followed by isolation of the desired product. n The compounds according to the present invention are employed for the synthesis of asymmetric compounds of 3,4,9,10-perylenetetracarboxylic acid, as well as for dyeing and printing of textile materials with the formation, on the material, of asymmetric compounds of 3,4,9,10-perylenetetracarboxylic acid having the following formula: ##STR4## wherein R 1 is hydrogen, halogen, or alkyl; when X is oxygen, Y is hydrogen, alkyl, cycloalkyl, or aryl containing at least one substituent from the group including; halogen, alkyl, or alkoxy, when X is nitrogen, Y is ##STR5## where R 2 is hydrogen, halogen, or alkyl; Y being linked with X to form a benzimidazole cycle. n The compounds according to the present invention dye textile materials to various shades of violet color.
