Storage method


Seal the secret container and store it in a sealed main container in a cool place Dry position.

Synthesis method

1. Production Method: Add phthalic anhydride into concentrated sulfuric acid, add water vapor while stirring and heat to 80℃, add fuming nitric acid dropwise, and maintain the reaction temperature100-110℃, plus Bi, in110Heating above ℃2h, leave overnight Then pour it into water and filter. The filter cake is recrystallized with water to obtain 3-Nitrophthalic acid. The yield is about 30%.


2. Use : Organic synthesis intermediates.
