2-Acrylamide-2-methylpropanesulfonic acid Chemical Properties, Uses, Production
Chemical Properties
2-Acrylamide-2-methylpropanesulfonic acid is a white crystals. The melting point is 195°C (decomposition). Soluble in water, the solution is acidic. Soluble in dimethylformamide, partially soluble in methanol, ethanol, insoluble in acetone. Slightly sour.
Uses
2-Acrylamide-2-methylpropanesulfonic acid has good complexion, adsorption, biological activity, surface activity, hydrolysis stability and thermal stability. It can be used in oil chemical, water treatment, synthetic fiber, printing and dyeing, plastics, water absorbing coatings, paper, bio-medical, magnetic materials and cosmetics industries.
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.
Definition
