White to Almost white powder to crystal.??
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.?? ??
1. 2-Methyl-2-propene-1-sulfonic acid sodium salt can be used as a monomer of high efficiency polycarboxylic acids concrete water reducing agents; offer stable sulfonic acid groups.2. It is mainly used as the third monomer to improve the dyeability, heat resistance,sense of touch and easily weaving of the polyacrylonitrile. Also it can be used on water treatment, paint additive, carbon pore creating and powdered paints.
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%.
