Title:
PROCESS FOR PREPARING AROMATIC IODINE COMPOUNDS
Document Type and Number:
WIPO Patent Application WO/2010/068051
Kind Code:
A3
Abstract:
The present invention relates to a process for preparing aromatic iodine compounds. The invention comprises iodination of non-halogenated aromatic compounds, a mono-iodine compound of aromatic compounds, a di-iodine compound of aromatic compounds, and iodine in the presence of zeolite catalysts under an oxygen atmosphere. The process for preparing aromatic iodine compounds according to the present invention prevents side-reactions resulting from simultaneous process of iodination and iodine conversion, and extends iodination catalyst life by enabling stable reaction temperature control. Therefore, the process can be used for mass production of di-iodine compounds.
