2-METHYL-2-PROPENE-1-SULFONIC ACID SODIUM SALT Usage And Synthesis

Uses	2-Methyl-2-propene-1-sulfonic acid sodium salt was used as anionic monomer to investigate the effect of different cationic or anionic moieties in acrylonitrile-based copolymers on the interaction with fibroblasts. It was used to reduce the homopolymerization during graft copolymerization of methyl methacrylate with water-emulsified solution onto preirradiated jute fiber.
Flammability and Explosibility	Flammable
Synthesis	The synthesis of 2-METHYL-2-PROPENE-1-SULFONIC ACID SODIUM SALT is as follows:The neutralization was carried out with sodium carbonate to pH 7. The neutralized filtrate was evaporated under reduced pressure (20 mmHg) to remove water and to obtain 46.5 g of white crystalline sodium methallyl sulfonate. The product was identified with a standard sample by IR spectrum. The purity of the product was 95.5% and the yield 95%.
