  Acrylic Acid:
The Basic Acrylic Monomer Manufacturers, Inc. (BAMM) is a trade association of manufacturers and importers of acrylic acid and its basic esters, including butyl acrylate, ethyl acrylate, methyl acrylate and 2-ethylhexyl acrylate.
The remaining one-third of the acrylic acid is used to produce polyacrylic acid, or crosslinked polyacrylic acid compounds, which have been successfully used in the manufacture of hygienic products, detergents, and waste water treatment chemicals.
The manufacture, transportation, and use of acrylic acid are regulated or addressed by a number of government agencies and other expert groups to control exposure to workers and the environment.

 Recovery of acrylic acid by reversal of acrylic acid/water relative volatility - Patent 4269666
Because of the relative volatilities between acrylic acid and water, fractional distillation of this stream is difficult and substantial losses of acrylic acid are realized in the separation.
Water-free acrylic acid is removed from the bottom of the tower through line 16, and an overhead stream containing approximately 15% acrylic acid with water is removed through line 14 and recycled back to the mixer.
For example, when an acrylic acid solution is saturated with calcium chloride, the azeotrope exists at approximately 43 wt.% acrylic acid in both the liquid and the vapor.

 Acrylic Acid/Acrylates - Market Size, Market Share and Demand Forecast;
Processes were and continue to be developed in which propylene is directly converted to acrylic acid or in which acrolein is first formed and further oxidized to acrylic acid.
Most acrylic acid contains furfural at a level of 2 ppm, although levels of up to 20 ppm may be found.
The second stage reaction, oxidation of acrolein to acrylic acid, proceeds at a much lower temperature than the first stage, and the gases exiting from the first stage must be cooled to the optimal operating temperature of the second stage catalyst.
