[0002] Anthranilic acid is a natural intermediate in the shikimic acid pathway and a precursor in the biosynthesis of the aromatic amino acid L-tryptophan. Industrially, it is used as an intermediate in the synthesis of dyes, fragrances, pharmaceuticals, and other valuable products. The acidification reaction of anthranilic acid requires a reaction-aiding device for stirring. However, current anthranilic acid acidification reaction aids require manual sampling and analysis to monitor the reaction progress and product quality, which is very cumbersome. Therefore, we propose an anthranilic acid acidification reaction aid. Utility Model Content
