Procedure
2600 grams of itaconic acid where dissolved in 1150 grams of water with 1600 grams of sodium hydroxide (50% w/w), at 60° C. to yield a clear solution of monosodium itaconate. Under mechanical stifling, 572 ml of sulfuric acid (93% w/w) where added at the rate of 10 ml/min, while the temperature was maintained at 60° C. The resulting slurry contained 2220 grams of crystalline itaconic acid, dispersed in a solution of sodium sulfate at 338 g/L, saturated in itaconic acid. Upon filtration, rinsing of the crystal with 30° C. water, and drying in a vacuum oven, high purity crystalline itaconic acid was recovered.
