  • Publication number: 20010023272
    Abstract: Ink jet recording media have a substrate coated on one or both sides with two layers of coating material. The first layer is a relatively inexpensive ink vehicle absorptive coating comprised in major part of a pigment component that is comprised in major part of relatively inexpensive but highly absorbent calcined clay. The second layer is an ink receptive coating comprised of relatively expensive constituents providing excellent print qualities. Because the first layer provides the important ink vehicle absorbing function, the ink receptive coating can be applied at much lower coat weights than would otherwise be required. This produces recording media having equal or better print qualities than a heavier single layer of the ink receptive material, and does so at much lower cost. Methods of making and applying coatings having high levels of calcined clay are key factors in producing the media.

The thermal treatment includes (a) heating a suspension of polymer particles of an appropriate size to a temperature effective to cause the polymer to become amorphous, and then (b) cooling the suspension of amorphous polymer particles below the melting point of the polymer at a rate effective to prevent substantial coalescence of the polymer particles. The method and apparati are effective for use with a variety of polymers having suitable crystallization parameters, although polyhydroxyalkanoate (PHA) polymers are preferred, particularly in an aqueous suspension medium. For PHA polymers, the polymer particles subjected to treatment preferably are of a size of less than 5 &mgr;m, or more preferably less than 1.5 &mgr;m in diameter.

    Abstract: The invention provides a process for purifying gallium alkoxides by decreasing the amount of impurity chlorine contained therein, gallium alkoxides which are useful as raw materials for the formation of dielectrics containing gallium oxide and as raw materials for the syntheses of compounds for photoelectronics. Gallium isopropoxide containing 0.98 weight percent of chlorine and potassium isopropoxide of 1.4 equivalents to the impurity chlorine are refluxed in toluene as a solvent for 5 hours, the solvent is distilled away, and the residue is simply distilled under vacuum to obtain gallium isopropoxide containing 0.022 weight percent of the chlorine in a 89% yield.

    Abstract: The present invention relates to 3-cyano-2,4,5-trifluorobenzoyl fluoride and to intermediates for its preparation and to the process for the preparation of 3-cyano-2,4,5-trifluoro-benzoyl fluoride, which starts from 5-fluoro-1,3-xylene (VIII); which is bichlorinated in the ring in the presence of a catalyst under ionic conditions to give 2,4-dichloro-5-fluoro-1,3-dimethylbenzene (VII). The latter is chlorinated in the side chains under free-radical conditions to give 2,4-dichloro-5-fluoro-3-dichloromethyl-1-trichloromethylbenzene (VI).

  • Publication number: 20010023303
    Abstract: The present invention relates to a method of recovering terephthalic acid from a material containing poly(ethylene terephthalate) (P.E.T.) in the form of bottles, by making said material react, in the absence of water, with a reagent consisting of one or more metal salts of a weaker acid than the terephthalic acid, until a water-soluble compound is obtained, and subsequently carrying out dissolution in water and acidification.
