标 题 :Continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts
发明人：MA BING; PAN SHUAI
权利人:SHANGHAI HYBRID—CHEM TECH; SHANGHAI HYBRID CHEM TECH
摘要:The present invention provided a continuous flow process for the synthesis of phenylhydrazine salts and substituted phenylhydrazine salts. Diazotization, reduction, acidic hydrolysis and salifying with acids are innovatively integrated together. Using acidic liquids of aniline or substituted aniline, diazotization reagents, reductants and acids as raw materials, phenylhydrazine derivative salts is obtained through the synthesis process, which is a three-step continuous tandem reaction including diazotization, reduction, acidic hydrolysis and salifying. The described synthesis process is a kind of integrated solutions, which is carried out in an integrated reactor. The feed inlets of the integrated reactor are continuously filled with raw materials. In the integrated reactor, diazotization, reduction, acidic hydrolysis and salifying are carried out continuously and orderly, and phenylhydrazine salts or substituted phenylhydrazine salts is obtained in the outlet of the integrated reactor without interruption. The total reaction time is no more than 20 min.

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.
