80 °C

In a crystalliser (500 ml open jacketed glass vessel) 100.1 g (0.848 mole) of succinic acid (Acros) and 19.9 g (0.074 mole) of sodium succinate hexahydrate (Acros) were dissolved in 281.5 g of demineralised water, by heating with the thermostatic bath to 80° C. This resulted in a clear solution with 25% of succinic acid and 3% of sodium succinate, representing a solution obtained from a water-splitting electrodialysis process with a conversion of 92 mole %. The solution was cooled from 80° C. to 20° C. in 5 hours with a linear cooling profile. During cooling nucleation took place between 56° C. and 50° C.
