Acrylic Acid

· Acrylic acid is an organic compound, the simplest unsaturated fatty acid, with the chemical formula C3H4O2. At room temperature and normal pressure, it is a colorless liquid with a pungent odor and is soluble in water (miscible), ethanol, ether, and other solvents. Due to the presence of unsaturated bonds in its structure, it is chemically reactive and prone to polymerization in the air. It can undergo reduction reactions with hydrogen, esterification reactions with alcohols, and addition reactions with halogen acids.

Acrylic acid is mainly used to prepare high molecular weight superabsorbent polymers, acrylates, and is also used in wastewater treatment and cleaning agents, etc. Among them, SAP is widely used in hygiene products such as sanitary napkins and diapers due to its ability to absorb hundreds to thousands of times its own weight in water, and this industry is also one of the faster-growing product areas for acrylic consumption in recent years; in addition, acrylates are widely used in coatings, adhesives, and other industries due to their excellent heat and water resistance.
