Procedure
The solution obtained in example 1 was acidified using an ion exchange resin. Acidification took place using Amberlite IR-120, a strong acid ion exchange resin: 55 g of GLDA solution, 110 g of Amberlite IR-120 as such, and ca 100 g of water were stirred in a 500 ml round-bottomed flask for at least 48 h. After filtering off the resin the solution was dried by evaporation of water at reduced pressure at 70° C. The light-coloured crispy foam obtained was further dried in a vacuum oven at 65° C. This resulted in a solid product in a yield of circa 85%.
