1.製品特性
Acrylic acid is a colorless, corrosive liquid with an acrid odor. Completely miscible with water and common organic solvents, it melts at 13 °C and boils at 140.9 °C under atmospheric pressure. Density is 1.051 g cm⁻³ at 20 °C; vapor pressure 1.33 kPa at 39.9 °C. Critical pressure reaches 5.66 MPa.

3.適用範囲と使用方法
Acrylic acid is the cornerstone monomer for super-absorbent polymers used in hygiene products and water-retaining gels. It copolymerizes to produce high-performance acrylic resins, pressure-sensitive adhesives, paints, textile finishes, and leather coatings. Its esters serve as building blocks for specialty plastics, detergents and scale inhibitors in water treatment.
4.パッケージと保管
Supplied in 200 kg epoxy-coated steel drums, 1000 kg IBC totes, or 20–24 m³ ISO tank containers. Small lab quantities are packed in 25 kg HDPE drums with vented bungs. Store in a cool, shaded area below 25 °C away from oxidizers, bases and peroxides; maintain 180–220 ppm MEHQ inhibitor. Ensure nitrogen blanketing and grounding during transfer to prevent polymerization and static discharge.
