2-Acrylamide-2-methylpropanesulfonic acid(Cas 15214-89-8) Usage
|
Uses and Mechanism of Action |
In superabsorbent polymer (SAP) synthesis: |
|
Production Methods |
Synthesized in labs using various methods including graft copolymerization and interpenetrating network formation. |
|
Analysis Method |
Characterized using FTIR, TGA, SEM, NMR, XRD, and conductivity measurements to understand structure and performance. |
|
Preparation |
2-Acrylamido-2-methylpropanesulfonic acid(AMPS) can be synthesized by one step and two steps. The one-step method is to react the raw materials acrylonitrile, isobutylene and oleum together. The two-step method is to sulfonate isobutylene in the presence of a reaction solvent to obtain a sulfonated intermediate, and then react with acrylonitrile in the presence of sulfuric acid. One-step method is more economical. Raw material consumption quota: isobutylene 300kg/t, acrylonitrile 290kg/t, oleum 560kg/t. |
|
Application |
2-Acrylamide-2-methylpropanesulfonic acid is an important monomer. Its copolymers or homopolymers with different molecular weight can be widely used in textile, oil drilling, water treatment, papermaking, dying, coating, cosmetics, electronics, etc. because of its unique formular structure—containing sulfonic acid group and unsaturated radical, thus showing excellent properties in many aspects. |
