Title:
COMPLEX OXIDE SOLID ACID CATALYST, SOLID ACID CATALYST, METHOD FOR CONDUCTING CHEMICAL REACTION USING THESE, AND PRODUCTION METHOD OF COMPLEX OXIDE SOLID ACID CATALYST
Document Type and Number:
Japanese Patent JP2023152408
Kind Code:
A
Abstract:
To provide a solid acid catalyst exhibiting high catalyst activity.SOLUTION: A solid acid catalyst of the present invention is a sulfated zirconia that is a lamellar crystal having a composition represented by general formula: Zr3SxOy nH2O (where, x is 0.95-1, y is 7-9, and n is 0-2). The sulfated zirconia exhibits crystallinity unlike the conventionally-known sulfated zirconia without crystallinity and has significantly higher acid catalytic activity compared to the conventionally-known sulfated zirconia. The sulfated zirconia of the present invention is prepared by hydrothermally reacting a solution obtained by dissolving a zirconia source in an aqueous solution of sulfuric acid.SELECTED DRAWING: Figure 1
