Hydrochloric Acid → HCID 70443216, compound

Participants

Reaction Steps

An acrylanilide sulfate co-polymer was synthesized by first suspending 17.7 g (0.1 mol) of p-hydroxymethacrylanilide in 100 ml of methylene chloride in a suitable glass reaction vessel and then adding 12 g of chlorosulfonic acid to the suspension. Hydrogen chloride gas was observed evolving during the addition; and the reaction mass was mechanically stirred overnight at room temperature. The resultant product was dissolved in a solution of 60 g water and about 10 g of 50% sodium hydroxide, giving a pH of about 11; and methylene chloride was then separated by vacuum. A yield of about 75% of sulfated monomer, observed to be a viscous liquid, was then determined using nuclear magnetic resonance techniques.
