Acrylic Acid is an unsaturated carboxylic acid, with the formula CH2=CHCO2H. Acrylic acid is clear and colourless liquid has a characteristic acrid odour. As it contains a polar carboxylic acid functional group, it is able to dissolve in water and is miscible with relatively polar organic compounds such as alcohols, ethers, and chloroform. Acrylic Acid is air and water sensitive as it reacts readily with free radicals and electrophilic or nucleophilic agents.Acrylic acid may polymerise in the presence of acids, alkalis, amines, peroxides, and iron salts. Prolonged exposure to heat or exposure of light acrylic acid also cause polymerisation. If confined, the polymerisation of acrylic acid can lead to explosion even at room temperature.Acrylic acid is corrosive to metals and tissues.
Both natural and synthetic polymers play important roles in everyday life. Selecting a suitable monomer is strongly recommended which later the polymer constructed from the selected or various monomers will produce polymer which has different properties, therefore generating various applications. Acrylic acid is one of the common monomers used to produce various polymers with a broad range of applications. Acrylic rubber, polyvinyl acetate, and polyacrylic acid are a few examples of polymers that contain acrylic acid as a raw material or monomer. The polymers mentioned are often used in coatings, adhesives, elastomers, plastics, and paints.

1. Vapor-phase oxidation : In the first step of the acrylic acid manufacturing process, the vapor-phase oxidation is conducted by mixing the propylene gas, steam, and air to obtain acrolein
2. Gas-phase oxidation : After vapor-phase oxidation, the oxidation is continued through the gas-phase oxidation which acrolein is converted into acrylic acid with the presence of a multicomponent catalyst consisting of vanadium and/or molybdenum
