  • Patent number: 9701610
    Abstract: Hydroxycarboxylic acids, e.g., 3-hydroxypropionic acid, and/or their ammonium salts are dehydrated to their corresponding unsaturated carboxylic acids, e.g., acrylic acid, by a process that uses a catalyst comprising ammonium bisulfate. The use of ammonium bisulfate reduces or eliminates the problems associated with processes that use sulfuric acid as a dehydrating catalyst, e.g, excess sulfuric acid consumption and/or recovery.

  • Patent number: 9464204
    Abstract: The present invention is a composition comprising a stable aqueous dispersion of polymer particles comprising structural units of a nonionic monoethylenically unsaturated monomer; 2-(methacryloyloxy)ethyl phosphonic acid (MEP) or a salt thereof; and a sulfur acid monomer or carboxylic acid monomer or a combination thereof or a salt thereof, as well as a composite comprising the polymer particles adsorbed to the surface of a pigment particle such as TiO2. The composition and composite are prepared using the phosphorus acid monomer MEP, which can be prepared in high purity with low residual non-polymerizable phosphorus acid, thereby reducing the load of neutralizing agent required to achieve the targeted pH as compared with phophoethyl methacrylate (PEM).
