AMPS (2-Acrylamido-2-methyl-1-propanesulfonic acid) – Product Introduction

AMPS, chemically known as 2-Acrylamido-2-methyl-1-propanesulfonic acid, is a highly functional sulfonated monomer with the CAS number 15214-89-8 and molecular formula C₇H₁₃NO₄S. This white crystalline compound features a strong anionic sulfonic acid group, a shielded amide group, and an unsaturated double bond, which collectively endow it with exceptional comprehensive performance .

Key Properties

AMPS exhibits outstanding water solubility (1500g/L at 20°C), excellent hydrolysis stability, and superior thermal stability. Its sodium salt solution demonstrates remarkable resistance to hydrolysis, particularly under alkaline conditions (pH > 9). In acidic environments, AMPS homopolymers show significantly better anti-hydrolysis performance compared to conventional polyacrylamide. The molecule possesses strong chelating ability, adsorption capacity, biological activity, and surfactant properties, making it highly versatile across multiple industries .

Primary Applications

Water Treatment: AMPS homopolymers and copolymers with acrylamide or acrylic acid serve as effective sludge dewatering agents in wastewater purification. They function as corrosion inhibitors for iron, zinc, aluminum, copper, and alloys in closed water circulation systems. Additionally, AMPS acts as a scale inhibitor and dispersant for heaters, cooling towers, air purifiers, and gas cleaning equipment. It is particularly suitable for high pH, high alkalinity, and high hardness water conditions .

Oilfield Chemistry: AMPS has rapidly expanded applications in the oil industry, including oil well cement additives, drilling fluid treatments, acidizing fluids, fracturing fluids, completion fluids, and workover fluid additives .

Other Industries: AMPS is widely used in synthetic fibers, dyeing and printing, plastics, superabsorbent coatings, papermaking, biomedical materials, magnetic materials, cosmetics, and polycarboxylate water reducers for concrete .

Product Specifications & Storage

AMPS is available in purity grades ranging from 98% to 99.75%. Standard packaging is 25kg per container. For optimal shelf life, store in a well-ventilated, cool, and dry indoor environment. The recommended storage period is one year .

Conclusion

AMPS represents a premium sulfonated monomer solution for demanding industrial applications. Its unique combination of stability, reactivity, and performance makes it an ideal choice for water treatment, oilfield operations, and advanced material synthesis. For specific application guidance and dosage recommendations, please consult with technical experts based on your particular use case.

Note: While AMPS demonstrates low acute toxicity compared to some alternative monomers, proper handling procedures should always be followed to ensure safety .
