Title:
AMORPHOUS HYDROUS TITANIUM OXIDE AND SOLID LEWIS ACID CATALYST CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2012/108472
Kind Code:
A1
Abstract:
Disclosed are: a novel substance which functions as a solid Lewis acid catalyst in the presence of water; a process for producing the same; use thereof as a solid Lewis acid catalyst; and a method for conducting a chemical reaction in an aqueous solution using the solid Lewis acid catalyst. Amorphous hydrous titanium oxide, which functions as a Lewis acid, can be obtained by subjecting an organotitanium compound which can be hydrolyzed in an aqueous solution to form an oxide to reaction with both water and an acid or base catalyst. This Lewis acid catalyst exhibits excellent effect in various reactions including a reaction of forming hydroxymethylfurfural from glucose.
