Acrylic Acid CAS#79-10-7
High Solubility & Reactivity
Fully miscible with water and soluble in ethanol, ether, chloroform and acetone. Contains carbon-carbon double bond and carboxyl group, with high reactivity for polymerization, addition and esterification.
Stability & Thermal Property
Pron to self-polymerization under heat, light and oxidants. Industrial grade is inhibitor-stabilized; store away from high heat and open flame.
Versatile Uses
Key organic monomer for acrylate and acrylic polymers. Used in water treatment, adhesives, coatings, textiles and daily chemicals.
Liquid Form & Corrosive Nature
Colorless liquid with strong pungent odor. Corrosive and irritating; store sealed and handle with strict protection.
Acrylic acid, molecular formula C3H4O2 (CH2=CHCOOH), is a colorless transparent volatile liquid with pungent odor. It is miscible with water, ethanol, ether and other organic solvents. It has strong reactivity and is easy to polymerize. It is corrosive, flammable and irritant. It is a core raw material for acrylic resin, acrylate and fine chemical synthesis.
