Cranial magnetic resonance imaging in 6 patients with glutaric aciduria type 1;

Activated carbon fiber(ACF) was used to purified glutaric acid from the mixture of binary acids(DBA),and by recrystallization the end production glutaric acid was purified.

Using a simple and reliable apparatus,the solubilities of glutaric acid in water,ethanol,toluene,chloroform,n-butanol and acetone are determined by the analytic method.

Diethyl glutarate was synthesized using glutaric anhydride and ethanol, which were separated from dicarboxylic acid, as raw material, heteropoly acid as catalyst.
