The extraction equipment ( Centrifugal extraction machine) Extraction of itaconic acid
is itaconic acid citric acid isomers. Tianyi extraction has been successful in fermentation production of itaconic acid, he in the water solubility is related to pH. PH3 solubility is small, when the pH greater than 3. 5 solubility up soon after.
itaconic acid extracted from extract common crystallization. When the high content of impurities extraction effect is good. Join the 100 - first 200 g/kg of NaCl, ethyl acetate extraction. Steamed to solvent vested itaconic acid.
