CH2CHCH2COOH

CH2CHCH2COOH, commonly known as acrylic acid, is a versatile organic compound with the chemical formula C3H4O2. It belongs to the class of unsaturated carboxylic acids, characterized by the presence of both a carboxyl group (–COOH) and a carbon-carbon double bond (C=C) in its molecular structure. The compound is typically represented as CH2=CH–CH2–COOH, indicating the double bond between the first and second carbon atoms.

Acrylic acid is a colorless liquid with a pungent odor, often used as a precursor in the synthesis of various polymers and derivatives. It is highly reactive due to its unsaturated nature, making it a key intermediate in industrial chemistry. The compound is soluble in water and many organic solvents, facilitating its use in numerous applications.

One of the primary industrial uses of acrylic acid is in the production of polyacrylic acid and its salts, which are employed in water treatment, paper manufacturing, and as superabsorbent polymers in diapers. It is also a building block for acrylic resins, used in coatings, adhesives, and textiles. Additionally, acrylic acid serves as a monomer for the synthesis of polyacrylates, which are widely utilized in paints, plastics, and synthetic fibers.

In laboratory settings, acrylic acid is often handled with caution due to its corrosive properties and potential to cause skin and eye irritation. Proper ventilation and protective equipment are recommended when working with the compound. Its polymerization can occur spontaneously under certain conditions, necessitating stabilizers in storage and transport.

Beyond industrial applications, acrylic acid and its derivatives play roles in pharmaceuticals, agriculture, and specialty chemicals. Research continues to explore new uses, including biodegradable materials and advanced functional polymers.
