Title:
HALOGENATION CATALYSTS AND PROCESS FOR PREPARING HALOGEN COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2012/086259
Kind Code:
A1
Abstract:
A halogenation catalyst that contains a transition metal oxide composite (a) represented by general formula (1) : AxMO(2+0.5x) [wherein A is an alkali metal, M is at least one transition metal element selected from the group consisting of chromium, manganese, cobalt, nickel and iron, and x is a number satisfying the relationship: 0 < x ≤ 3], and a halogenation catalyst that is composed of the transition metal oxide composite (a) and oxygen (b). Thus, a highly active catalyst which enables efficient progression of halogenation even under mild conditions and a catalyst which can be easily recovered after the completion of reaction and recycled to reaction can be provided.
