CARBON NITRIDE HETEROGENEOUS CATALYST CONTAINING RHODIUM, PROCESS FOR PRODUCING SAME, AND PROCESS FOR PRODUCING ACETIC ACID USING SAME

摘要

The present invention relates to a carbon nitride heterogeneous catalyst containing rhodium, a process for producing the same, and a process for producing acetic acid using the same. The heterogeneous catalyst containing rhodium in a carbon nitride support according to the present invention is characterized in that, unlike typical homogeneous catalytic reaction in which reactants and a catalyst are in the same phase, the rhodium metal is contained in carbon nitride which is a support insoluble in a liquid solvent, such as water or alcohol, and thus, the catalyst can be easily separated from a resulting product even by a simple process such as filtration. Accordingly, disadvantages of a process using conventional homogeneous catalysts can be overcome, and it is possible to minimize a phenomenon in which rhodium is leached, and thus the carbon nitride heterogeneous catalyst can be useful for the production of acetic acid through a carbonylation reaction between methanol and carbon monoxide since the catalyst has excellent long-term stability and activity of a catalyst compared to the results of typical homogeneous catalytic reactions.
