  • Method for production of aqueous (meth)acrylic acid
    Patent number: 8044237
    Abstract: The present invention relates to recovery of aqueous (meth)acrylic acid by condensation of a (meth)acrylic acid-containing stream to produce aqueous (meth)acylic acid having a higher concentration of (meth)acrylic acid and a lower concentration of formaldehyde, i.e., not more than 0.1 weight %, than the aqueous (meth)acrylic acid produced using hithertofore known separation methods. The (meth)acrylic acid-containing stream may be the raw product stream of catalytic oxidation at least one C2-C4 alkane or alkene.
    Type: Grant
    Filed: June 1, 2009
    Date of Patent: October 25, 2011
    Assignee: Rohm and Haas Company
    Inventors: Keith F. Briegel, Michael Stanley DeCourcy, James Elder, James Jerrick Juliette, Joy Lydon Mendoza
  • Method for production of purified (meth)acrylic acid
    Patent number: 8044238
    Abstract: The present invention relates to reducing corrosion of distillation equipment during azeotropic distillation of (meth)acrylic acid in the presence of dissolved copper, by providing aqueous (meth)acrylic acid having not more than 0.1% by weight formaldehyde, based on the total weight of the aqueous (meth)acrylic acid. The source of the copper may, for example, be copper-based polymerization inhibitors added to the aqueous (meth)acrylic acid and/or distillation equipment.
