  • Patent number: 9242232
    Abstract: There is provided a hetero polyacid-based catalyst for methacrylic acid production, which is more excellent in performance, life and moisture absorption during storage, the catalyst being a catalyst for methacrylic acid production, wherein a proton is replaced so as to satisfy conditions of ?=A+(B×C) and 0.5???1.4 when the atomic ratio of the alkali metal atom relative to 10 atoms of Mo is taken as A and the atomic ratio of the copper atom relative to 10 atoms of Mo is taken as B in MoaPbVcCudYeZfOg where Y represents cesium or the like; Z represents iron or the like; and a to g represent each an atomic ratio of each element relative to 10 atoms of Mo.

  • Patent number: 9133613
    Abstract: [Problem] The present invention relates to: a heat ray shielding adhesive which is used in bonding to a windowpane and the like and shields heat rays; a heat ray shielding transparent adhesive sheet; and a method for producing the heat ray shielding adhesive. The present invention provides a heat ray shielding transparent adhesive sheet which has high transmittance in the visible light region, low haze and more excellent transparency. [Solution] Transparency and heat ray shielding properties can be imparted in a simpler manner by using a heat ray shielding adhesive composition which contains fine heat ray shielding particles that have a half-value width of the first main peak of from 0.01° to 0.80° (inclusive) as determined by X-ray diffraction pattern, and a heat ray shielding transparent adhesive sheet is therefore able to be produced at low cost.
