properties and stability
properties and stability:
no decomposition products may occur under normal temperatures and pressures.
storage method
storage:
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%.
purpose
2. use : organic synthesis intermediates.
