Acrylic Acid (99.5%) - China
Acrylic acid is an unsaturated carboxylic acid, with the formula CH2=CHCO2H. This 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. It may polymerise in the presence of acids, alkalis, amines, peroxides, and iron salts. Prolonged exposure to heat or exposure of light can also cause polymerisation. If confined, the polymerisation of acrylic acid can lead to explosion even at room temperature. It is corrosive to metals and tissues.

Applications
Intermediate Chemicals Industry
Acrylic acid is primarily used as starting material for preparation of chemicals such as methyl acrylate, ethyl acrylate, butyl acrylate and 2-ethylhexyl acrylate. These monomers are polymerised, and are used in hygiene products with superabsorbent resins such as disposable diapers, in water-based paints and coatings, construction adhesives and pressure-sensitive adhesives, coatings for textiles, wood and paper, in leather finishing etc.
They also function mainly as an intermediate for the production of acrylate esters which are used to produce plastic additives, adhesives, coatings, textiles and paints. However, due to environmental concerns, their production was stopped.
Paint Industry
Acrylic acid is used in the manufacture of plastics, in latex applications, in floor polish, in polymer solutions for coatings applications, emulsion polymers, paint formulations, leather finishings, and paper coatings.
Acrylics are produced from acrylic acid through a two-step process. They are commonly used in the coatings industry and also used in their sheet forms due to their durability and clarity. In the first step, a reaction between the acrylic acid and an alcohol will produce an alkyl acrylate, which is a monomer of acrylics. After which, the second step is the polymerisation of the monomer to form acrylics. A radical is added to one end of the double bond of the alkyl acrylate to give a radical monomer before polymerising. The properties of the resulting acrylics are dependent on the nature of the alkyl groups on the acrylic acid and alcohol.
Waste Water Treatment Industry
Acrylic acid monomers are copolymerized and are used in waste water treatment. They are used in flocculation of mineral ore fines and waste water, and treatment of sewage.
Other Applications
Usage of acrylic acids has various applications over different industries. They can be found in acrylic nail polish in the cosmetic industry.
