Water → 3,3′-(1,2-Ethanediyldiimino)bis[1-propanesulfonic acid]

Participants

Reaction Steps

Into a four-necked flask containing ethylenediamine (3 g, 0.05 mol) and water (50 g), propanesultone (12.3 g, 0.1 mol) was added dropwise over 30 minutes. The contents were mixed for 2 hours, after which ethanol was added thereto. The mixture was subjected to filtration and then was washed with ethanol to obtain 13.5 g of N,N'-bis(3-sulfopropyl)ethylenediamine (separation yield: 88 wt %).
