  • Adsorbent composition for malodorous gases
    Patent number: 5135904
    Abstract: A zinc oxide-hydroxide complex produced by heating freshly prepared zinc hydroxide at a temperature from about 150.degree. C. to about 450.degree. C. is useful as an adsorbent for malodorous gases such as hydrogen sulfide, mercaptans and the like. The complex alone or its combination with aluminum dihydrogen tripolyphosphate may be incorporated into a synthetic thermoplastic resin for fabricating shaped plastic articles for deodorant uses.
    Type: Grant
    Filed: October 23, 1990
    Date of Patent: August 4, 1992
    Assignee: Tayca Corporation

  • Production and use of crystalline hydrogen-phosphate compounds having layer structure
    Patent number: 5085845
    Abstract: A process for preparing a crystalline layered hydrogenphosphate in a shortened period of time in high efficiency, which comprises reacting a tetravalent metal compound with phosphoric acid or its salt at an elevated temperature with introducing steam into the reaction system. Crystalline layered cerium(IV) bis(hydrogen-phosphate), particularly cerium(IV) bis(hydrogen-phosphate) dihydrate prepared by the above process, has an excellent ability of selectively adsorbing cesium ion, and is useful as a cesium ion adsorbent.
