Industrial production is by gas-phase catalytic oxidation of propylene.
Roughly three-quarters of production is converted directly into acrylate esters and the rest is purified into glacial acrylic acid. Construction is expected to begin later this year, leading to a startup in 2001. Elf Atochem will build an adjacent butyl acrylate plant that will use the company's share of CAA from the American Acryl plant. Rohm and Haas' plans for a grassroots acrylic acid and esters plant at a site in Antwerp, Belgium, are on hold until at least 2003. Startup of the project, which includes esters, is scheduled for 2000.
