I/We Claim:
1. A modified aluminosilicate, comprising one or more elements selected from the group
consisting of Group 4 elements and Group 5 elements on the periodic table, and
exhibiting an absorbance at 300 nm (A[300]) in an ultraviolet visible spectrum of 1.0 or
higher.
2. The modified aluminosilicate as claimed in claim 1, wherein a ratio (A[300]/A[210]) of
the absorbance at 300 nm (A[300]) in the ultraviolet visible spectrum to an absorbance
at 210 nm (A[210]) in the ultraviolet visible spectrum is 0.5 or higher.
3. The modified aluminosilicate as claimed in claim 1, wherein the modified
aluminosilicate has crystallineness and porousness.
4. The modified aluminosilicate as claimed in claim 3, wherein the modified
aluminosilicate has an MSE framework.
5. The modified aluminosilicate as claimed in claim 1, wherein the element is one or more
elements selected from Group 4 elements.
6. The modified aluminosilicate as claimed in claim 1, wherein the element is titanium.
7. The modified aluminosilicate as claimed in claim 6, wherein a molar ratio ([Si]/[Ti]) of
silicon to titanium is in the range of 0.1 to 100.
8. A catalyst for manufacturing an aromatic dihydroxy compound, comprising the modified
aluminosilicate.
9. A method for manufacturing an aromatic dihydroxy compound, comprising a step of
reacting a phenol with hydrogen peroxide in the presence of the catalyst for
manufacturing an aromatic dihydroxy compound.
