Acrylic Acid
Acrylic Acid (C3H4O2) is an organic compound and the simplest unsaturated carboxylic acid. It is a clear, colorless liquid with a distinctively acrid odor. Produced primarily via the oxidation of propylene, it is a vital industrial chemical used as a monomer for polyacrylic acid and its derivatives. It is highly valued for its ability to undergo radical polymerization, making it essential in the production of superabsorbent polymers, plastics, and coatings. Due to its reactive nature, it is typically inhibited with MEHQ to ensure stability during transport.
Applications
- Raw material for the production of Superabsorbent Polymers (SAP) used in hygiene products.
- Manufacture of acrylic esters (Butyl Acrylate, Ethyl Acrylate, 2-Ethylhexyl Acrylate).
- Formulation of water-based architectural and industrial coatings.
- Synthesis of scale inhibitors and dispersants for water treatment.
- Production of specialty resins for adhesives and sealants.
- Ingredient in textile finishes and leather treatment chemicals.
Industries served
- Hygiene and Personal Care Equipment
- Paints, Coatings, and Inks
- Water Treatment Chemicals
- Adhesives and Sealants
- Textile and Leather Processing
- Construction Chemicals
Key benefits
- High reactivity due to the presence of both double bonds and carboxylic acid groups.
- Excellent polymerization versatility to create various homopolymers and copolymers.
- Enhances durability and weatherability in coating applications.
- Superior water absorption properties when converted to polyacrylates.
- Miscible with water, alcohols, and ethers.

Storage
Store in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Maintain storage temperatures between 15°C and 25°C. Storage containers should be constructed of stainless steel or polyethylene. Avoid contact with carbon steel or copper, which can cause discoloration or catalyze polymerization. Ensure an atmosphere containing 5-21% oxygen is present above the liquid to maintain inhibitor effectiveness.
Handling
Use only in a well-ventilated area. Avoid contact with skin, eyes, and clothing. Use explosion-proof equipment. Do not use compressed air for filling, discharging, or handling. Monitor stabilizer levels if stored for extended periods. Ensure the temperature remains above 15°C to prevent freezing, but below 25°C to prevent premature polymerization.
Transport
UN Number: 2218; Proper Shipping Name: Acrylic Acid, Stabilized; Class: 8 (6.1); Packing Group: II. Transport must comply with IMDG/ADR/IATA regulations for corrosive and flammable liquids.
