  • Process for preparing layered double hydroxide comprising carbonate
    Patent number: 8241601
    Abstract: The invention relates to a process for the production of a layered double hydroxide comprising carbonate by preparing a divalent and trivalent metal ion source-containing slurry, which is subsequently treated solvothermally. If the slurry does not contain a divalent metal ion source containing carbonate, a carbonate source is added during or after the solvothermal treatment.

  • PAPER SIZING ADDITIVES, THEIR PREPARATION PROCESS, AND THEIR USE
    Publication number: 20110054192
    Abstract: The present invention pertains to a process for the preparation of an alkenyl-substituted cyclic anhydride compound comprising the steps of subjecting one or more olefinically unsaturated C6-C28 hydrocarbons of which at least 30% by weight is alpha-olefin to a double bond isomerization step by contacting them with a catalyst comprising an alkali metal on a carrier, and reacting the resulting isomehzed olefinic C6-C28 hydrocarbons with a cyclic anhydride of an unsaturated dicarboxylic acid to form the alkenyl-substituted cyclic anhydride compound. Furthermore, it pertains to the thus obtained alkenyl-substituted cyclic anhydride and to its use as a paper additive.
