  • Patent number: 6060627
    Abstract: A water and allylic compound containing propoxylated glycerin stream is reduced in water content by evaporation and flashed at reduced pressure and elevated temperature to reduce the water content to 1000 ppm or less, and thereafter stripping allylic impurities from the propyxylated glycerin.
    Type: Grant
    Filed: May 8, 1997
    Date of Patent: May 9, 2000
    Assignee: Arco Chemical Technology, L.P.
    Inventor: Jon R. Valbert
  • Patent number: 6002030
    Abstract: A process is provided for the fatty acid esterification of propoxylated glycerin wherein fatty acids stripped from the esterifier and/or fatty acids stripped from the esterification product are scrubbed by contact with a scrubbing liquid which is maintained at a temperature above the fatty acid melting point.
    Type: Grant
    Filed: May 8, 1998
    Date of Patent: December 14, 1999
    Assignee: ARCO Chemical Technology, L.P.
    Inventor: Jon R. Valbert
  • Patent number: 4855179
    Abstract: Superabsorbent articles in the form of soft, nonwoven fibrous webs are produced from aqueous fiber-forming polymer solutions by forming the polymer into water soluble filaments, contacting the filaments with a primary air stream having a velocity effective to attenuate and to partially dry the filaments, contacting the attenuated filaments with a secondary air stream having a velocity effective to fragment the filaments into fibers and to transport the fibers to a web-forming zone while also further attenuating and drying the fibers, collecting the fibers in reticulated web-form in the web-forming zone and curing the web to a water insoluble state. The temperature and air stream velocities are controlled with respect to ambient humidity and water content of the fiber during the fiber and web formation such that the fibers are collected without sticking. Collection is preferably on a wire belt followed by transport through a curing oven to compacting rolls and web take-up.

  • Patent number: 4045294
    Abstract: Ethylene glycol or 1,2-propylene glycol contained in mixtures with lower carboxylate esters of the glycol is recovered by azeotropic distillation of the mixtures with an azeotroping agent which is a hydrocarbon which has a boiling point at atmospheric pressure above 190.degree. C but at most about 220.degree. C and is free from linear secondary and tertiary hydrogen atoms.
