  • Process for the manufacture of sodium silicate
    Patent number: 4336235
    Abstract: The present invention comprises a process for the manufacture of a sodium silicate solution in a continuous manner from a silicon dioxide-containing material, comprising continuously adding to a reaction zone a stream of said silicon dioxide-containing material and a stream of a sodium hydroxide-sodium carbonate solution, reacting said silicon dioxide-containing material and said sodium hydroxide-sodium carbonate at a temperature and pressure and for a time sufficient to form a sodium silicate solution, and recovering said sodium silicate solution from the reaction zone.
    Type: Grant

    Date of Patent: June 22, 1982
    Assignee: Produits Chimiques Ugine Kuhlmann
    Inventor: Jean Deabriges
  • Industrial process for continuous production of zeolite A
    Patent number: 4314979
    Abstract: A process for continuous preparation of zeolite A of constant and homogeneous quality, consisting of instantly and continously mixing a sodium silicate solution and a sodium aluminate solution in the correct proportions and at an elevated temperature followed by transfer of the resulting slurry to a crystallization reactor. The product is recovered from the crystallization reactor washed and dried.

  • Process of formation of color images, photographic product and treating solutions useful for putting the process into practice
    Patent number: 4273863
    Abstract: A process of forming color images comprises imagewise exposing a silver halide photographic color image-transfer product comprising an image dye-providing compound in the presence of a silver halide developer, and treating the exposed photographic product with an alkaline processing composition in the presence of an amino acid or a combination of an acid and an amine. Color images are achieved having excellent image discrimination (Dmax-Dmin).
