Acrylic acid

Acrylic Acid

Acrylic acid (pronunciation: /əˈkrɪlɪk ˈæsɪd/) is an organic compound with the formula CH2=CHCOOH. It is the simplest unsaturated carboxylic acid, consisting of a vinyl group connected directly to a carboxylic acid terminus. This colorless liquid has a characteristic acrid or tart smell. It is miscible with water, alcohols, ethers, and chloroform. More than a million tons are produced annually.

Etymology

The term "acrylic" is derived from the Latin word "acrolein" meaning "sharp smell," and the Greek word "akros" meaning "highest" or "outermost," referring to its strong, pungent odor. The "-ic" suffix is derived from the Latin "-icus" and is used in chemistry to denote substances related to or derived from the preceding element or compound.

Synthesis

Acrylic acid is produced by oxidation of propene, a byproduct of ethylene and gasoline production. It's a key raw material in the production of superabsorbent polymers and a precursor to other monomers, polymers, and cross-linking agents.

Uses

Acrylic acid and its esters, methacrylates, have a wide range of applications including coatings, adhesives, sealants, textiles, and plastic additives. They are also used in the production of pharmaceuticals and personal care products.

Health Effects

Exposure to acrylic acid can cause irritation to the skin, eyes, and respiratory tract. It can also cause nausea, vomiting, and burns in high concentrations.
