Method for producing modified aluminosilicate, modified aluminosilicate, and method for producing aromatic polyhydroxide compound using same

Abstract

Provided is a method for manufacturing a modified aluminosilicate in which a hydroquinone is highly selectively manufactured by a reaction between a phenol and hydrogen peroxide under industrially advantageous conditions, wherein the manufacturing method includes: a second step for treating an aluminosilicate with an acid; a third step for performing primary calcination of the treatment product obtained in the second step; and a fourth step in which the primary calcined product obtained in the third step and liquid containing one or more elements selected from the group consisting of elements in Group 4 and Group 5 of the Periodic Table are brought into contact with each other, and drying and secondary calcination then performed.

Dependencies are inferred from the claim text.
