Title:
HALOGENATION CATALYST AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2013/081034
Kind Code:
A1
Abstract:
A halogenation catalyst for halogenating an aromatic ring, which is characterized by being obtained by having iron oxide or zinc oxide supported by a carrier that is formed of a complex oxide that contains silicon and aluminum. In this connection, it is preferable that the halogenation catalyst is a bromination catalyst for brominating an aromatic ring. It is also preferable that 0.1-10 mmol of elemental iron or elemental zinc is contained per 1 g of the complex oxide. It is also preferable that the ratio of the silicon atoms to the aluminum atoms in the complex oxide, namely Si/Al is 1-1,000. Consequently, a halide is able to be obtained with a high yield.
