Patents Assigned to Ehime Prefectural Government
  • Cellulose solution manufacturing method, cellulose precipitate manufacturing method, cellulose saccharification method, cellulose solution, and cellulose precipitate
    Patent number: 9522991
    Abstract: The invention relates to a cellulose solution manufacturing method including: performing an ozonation treatment to bring a cellulose-containing material and ozone into contact with each other; and performing an alkali treatment to bring the obtained treated material and an alkali aqueous solution into contact with each other, thereby dissolving at least cellulose in the cellulose-containing material brought into contact with the ozone in the alkali aqueous solution. According to the invention, it is possible to provide a method of manufacturing a cellulose solution in which cellulose can be dissolved in a more simple manner, a method of manufacturing a cellulose precipitate in which cellulose can be recovered from the cellulose solution, and a method of saccharifying cellulose which uses the cellulose precipitate.

  • Method for producing functional material, functional material, sheet-like structure and sanitary product
    Patent number: 9101911
    Abstract: Provided is a method for producing a functional material, including the steps of: bringing a polyvalent metal cation aqueous solution into contact with a base material; bringing a polyanion aqueous solution containing a functional component into contact with the base material previously in contact with the polyvalent metal cation aqueous solution to bond the polyvalent metal cations and the polyanions to each other, and thereby forming an insoluble compound containing the functional component; and drying the base material including the insoluble compound.
