  • Oxidative purification method for producing purified dry furan-2,5-dicarboxylic acid
    Patent number: 9156805
    Abstract: Disclosed is a process to produce a dry purified carboxylic acid product comprising furan-2,5-dicarboxylic acid (FDCA). The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising FDCA, removing impurities from a crude carboxylic acid slurry via oxidative purification in a low temperature post-oxidation zone to form a low impurity slurry stream. The low impurity slurry stream is further treated in a high temperature post oxidation zone to produce a secondary oxidation slurry stream which is routed to a crystallization zone to from a crystallized slurry stream.
    Type: Grant

  • Toy articles of manufacture comprising spontaneously wettable fibers
    Patent number: 5346422
    Abstract: This invention relates to an article of manufacture consisting of a toy having a plurality of synthetic fibers capable of spontaneously transporting water on the surface thereof, said fibers satisfying the following equation(1-X cos .theta..sub.a)<0,wherein.theta..sub.a is the advancing contact angle of water measured on a flat film made from the same material as the fiber and having the same surface treatment, if any,X is a shape factor of the fiber cross-section that satisfies the following equation ##EQU1## wherein P.sub.w is the wetted perimeter of the fiber and r is the radius of the circumscribed circle circumscribing the fiber cross-section and D is the minor axis dimension across the fiber cross-section.
