Acrylic acid is a clear, colourless liquid with a distinctive pungent odour which is soluble in water and miscible with alcohols and ethers.It is a simple unsaturated monocarboxylic which, consisting of a vinyl group connected to a carboxylic acid terminus, will undergo the reactions of both. It is used in the manufacture of polymers and acrylate esters and as an intermediate for chemical syntheses.
Acrylic acid is a versatile chemical valued for properties such as flexibility, weatherability, adhesion, hardness and resistance to abrasion and oils.
Synonyms: 2-Propenoic Acid, prop-2-enoic acid, propenoic acid, propene acid, acroleic acid, vinyl formic acid, carboxyethylene, ethylenecarboxylic acid
Applications of Acrylic Acid
Acrylic acid is used as an additive in a wide range of copolymer-based finishes including coatings, adhesives, inks, lubricants, saturants and plastics. It is also used in the production of esters for a number of specialist applications including water treatment chemicals, drilling fluids, mineral processing chemicals, detergent builders and superabsorbents. Acrylic acid is a superabsorbent polymer (SAP), and as such it is used in the production of nappies and other sanitary products. It may also be copolymerised with acrylamides to act as a flocculant in water and sewage treatment.
Acrylic acid is widely used in textile, leather and paper finishes, floor polishes, exterior paints, vehicle paint, lacquers, plastics, adhesives, scale inhibitors, dispersants, saturants and thickeners as well as in hair styling and finishing products,.
Storage and Handling
Acrylic acid polymerizes readily, therefore it is supplied in stabilised form and must be stored under air rather than inert gases. Storage temperature should be between 15°C and 25°C. Under these storage conditions the product can be expected to remain stable for one year. However, it should be noted that diacrylic acid forms during storage and this may affect performance in certain applications.
The product must be stored, handled, distributed and disposed of in strict accordance with national laws and directives, as well as any applicable local regulations. Ensure the container is tightly closed. More detailed information is available in the brochure ‘SAFE HANDLING AND STORAGE OF ACRYLIC ACID’, from the European Basic Acrylic Monomers Manufacturers Association (EBAM).
