Dear All,

I am trying to synthesize 1,2,3,4-Butanetetracarboxylic Acid (CAS NO.
1703-58-8) by Na2WO4 catalyzed oxidation of tetrahydrophthalic anhydride
with 30% hydorgen peoxide as oxidant. However, it is very difficult to
recrystallize the target product from water althouth the solubility of
target product in water is 10 g/100 mL at 19 C.

Any advice and suggestion is appreciated.

thanks

H. jiang
