HETEROPOLYACID CATALYSTS, THEIR PREPARATION AND PHOTOCATALYTIC PROCESS

摘要

A process for migrating C=C double bonds within an unsaturated organic compound is described. The process involves contacting an unsaturated organic compound starting material with a heteropoly acid catalyst in the presence of light having a wavelength of less than or equal to 700 nm. Also described is a process for the preparation of heteropoly acids having increased surface area.
