Title:
METHOD FOR MANUFACTURING MODIFIED ALUMINOSILICATE, MODIFIED ALUMINOSILICATE, AND METHOD FOR MANUFACTURING AROMATIC DIHYDROXY COMPOUND USING SAME
Document Type and Number:
WIPO Patent Application WO/2019/225549
Kind Code:
A1
Abstract:
Provided are: a method for manufacturing a modified aluminosilicate, the method involving the highly selective manufacturing of a hydroquinone via a reaction of a phenol and hydrogen peroxide under industrially favorable conditions; a modified aluminosilicate; and a method for manufacturing an aromatic dihydroxy compound using the modified aluminosilicate. This method for manufacturing a modified aluminosilicate comprises a first step for treating an aluminosilicate with an acid, a second step for subjecting the treated product obtained from the first step to primary firing at 550-850 °C, and a third step for causing the fired product obtained from the second step to come into contact with a liquid containing one or more elements selected from the group consisting of group 4 elements and group 5 elements in the periodic table, and then subjecting the result to drying and secondary firing. The modified aluminosilicate contained in the present invention comprises one or more elements selected from the group consisting of group 4 elements and group 5 elements in the periodic table, and exhibits an absorbance at 300 nm (A [300]) in the UV-visible spectrum of at least 1.0. This method for manufacturing an aromatic dihydroxy compound comprises a step for reacting a phenol with hydrogen peroxide in the presence of a specific modified aluminosilicate.
