Green production method of 1, 1 '-binaphthyl-8, 8'-dicarboxylic acid

The invention is applicable to the technical field of organic dyes, provides a green production method of 1, 1 '-binaphthyl-8, 8'-dicarboxylic acid. The method comprises the following steps: a reduction buffer reaction system is designed and prepared by taking a copper ammonia solution as a catalyst; then 1-amino-8-naphthoic acid diazonium salt is synthesized, and when the diazonium salt is slowly added into a reduction buffer reaction body, a catalyst copper diammine (I) in the reduction buffer reaction system is oxidized into copper tetrammine (II); then, generated tetraamminecopper (II) is reduced into diamminecopper (I) by hydroxylamine salt in the reaction system to complete regeneration of the catalyst, and the regenerated catalyst immediately and continuously reacts with 1-amino-8-naphthoic acid diazonium salt which is subsequently dripped into the reaction system; and the steps are repeated until the reaction is finished. According to the reaction, nitrogen is generated in the consumption and regeneration process of the catalyst and overflows out of a reaction system in time, so that the reaction is rapid and thorough, and the yield is about 10% higher than that recorded in the literature.
