Miscible with water, alcohol and most oils and perfume/flavor chemicals.
Its odor resembles that of acetic acid, but it is more acrid, corrosive to human mucous membranes, irritating to the eyes. Polymerizes in air, unless properly stabilized. The polymers are mostly solid and odorless.
Rarely used in perfumery, occasionally used in flavor work. Esters of acrylic acid are used in certain industrial perfumes.
Produced by dehydration of Ethylene cyanohydrin, or Acetaldehydecyanhydrin, followed by hydration. Many other methods are used commercially, since Acrylic acid is an important chemical intermediate.
