ACRYLIC ACID (AA)
Product catalog summary
Specifications
Acrylic Acid (AA) has a chemical formula of CH2=CH-COOH and a molecular weight of 72. It is also known as 2-Propenoic acid. The purity is specified to be a minimum of 99.5% as determined by Gas Chromatography (GC). The appearance is confirmed by visual inspection, and the color is limited to a maximum of 10 PT-CO. The inhibitor concentration is between 180-220 ppm MEHQ, and the water content is a maximum of 1000 ppm.

Main Physical Characteristics
Acrylic Acid has a boiling point of 141.3°C at 1013 mbar and a freezing point of 13°C. It is a liquid above 13°C and solid below this temperature. The specific gravity is 1.049 at 20°C and 1.043 at 25°C. It has a refractive index of 1.422 at 20°C and 1.418 at 25°C. The viscosity is 1.22 mPa.s at 20°C and 1.15 mPa.s at 25°C. It is infinitely soluble in water at 20°C. The specific heat in the liquid state is 2.09 kJ/kg°C, with a latent heat of vaporization of 621 kJ/kg and a heat of polymerization of 1074 kJ/kg. The flash point in a closed cup is 54°C, with a lower explosion limit of 2.4% by volume. The vapor pressure is 4 mbar at 20°C, 8 mbar at 30°C, and 24 mbar at 50°C. The auto-ignition temperature is 429°C.

Chemical Properties
Acrylic Acid can form salts, anhydrides, acid chlorides, and esters due to its acid function. The double bond allows for addition, cyclization, polymerization, and copolymerization reactions. Specific copolymerization reactivity ratios with various monomers are provided.

Packaging and Storage
Acrylic Acid is delivered in stainless steel railcars, tank trucks, or polyethylene drums. It should be stored at 18-25°C to prevent crystallization and ensure inhibitor distribution. Storage should be indoors, away from light, and under an air atmosphere to maintain inhibitor effectiveness. The product is guaranteed for one month after delivery. It is highly corrosive and should be stored in glass, stainless steel, or polyethylene containers. If crystallization occurs, warm the product slowly while agitating, not exceeding 25°C to avoid exothermic polymerization. Avoid excessive storage periods to prevent dimer formation.
