Glutaric acid is a water-soluble saturated dicarboxylic acid . The salts and esters of glutaric acid are called glutarates .
Occurrence and synthesis
Glutaric acid is e.g. B. found in the juice of unripe sugar beet . The synthesis can take place, for example, by hydrolysis of glutaronitrile ; Technically, one oxidizes cyclopentanone with nitric acid and vanadium (V) oxide .
properties
Glutaric acid is a flammable, light-sensitive, colorless and almost odorless solid that is easily soluble in water. Its aqueous solution is acidic.
use
Glutaric acid can be used to make 1,5-pentanediol by hydrogenation .
safety instructions
Glutaric acid is acutely irritating to the eyes and respiratory tract.
