実験手順

A solution of 3 g of 1,2-ethanedisulphonic acid disodium salt in 10 ml of water is introduced slowly into 200 ml of Dowex® 50 W×8 resin, and the product is eluted with 200 ml of demineralized water. The eluate is diluted by adding EtOH and concentrated under vacuum. 3.35 g of the expected product are obtained in the form of an oil which crystallizes at RT.
