  • Clathrate compound, method for controlling concentration of aqueous agricultural chemical active ingredient solution, and agricultural chemical formulation
    Patent number: 7737309
    Abstract: The present invention provides a clathrate compound characterized by containing: a polymolecular host compound as a host compound; and an agricultural chemical active ingredient having a saturated solubility in water at 25° C. of not less than 500 ppm as a guest compound. The present invention also provides a method for controlling the concentration of an aqueous agricultural chemical active ingredient solution, characterized by containings a step of including an agricultural chemical active ingredient having high saturated solubility in an interior space formed of a polymolecular host compound, thereby maintaining the saturated solubility of the agricultural chemical active ingredient in water within a predetermined concentration range. The present invention also provides an agricultural chemical formulation containing the clathrate compound. The present invention also provides an agricultural active composition containing the clathrate compound and a synthetic pyrethroid.

  • Binders for forming a ceramics sheet and applications thereof
    Patent number: 5248712
    Abstract: A binder for preparing an aqueous ceramics slurry, which contains a hydrophilic polymer such as a water-soluble (meth)acrylic polymer, a polysaccharide of natural origin such as pectin, pectinic acid, glucan, etc., and a polyvinyl compound such as poly(vinyl butyral). The aqueous ceramics slurry contains less than 25 parts by weight of the binder to 100 parts by weight of ceramics powder. The slurry is applied on a carrier film by a doctor blade method and dried to give a ceramics green sheet. A ceramics sheet can be produced by sintering the green sheet.
