Abstract
This invention relates to a catalyst for use in the preparation of acetic acid through a methanol carbonylation reaction using carbon monoxide, and particularly to a heterogeneous catalyst represented by Rh/C3N4 configured such that a complex of a rhodium compound and 3-benzoylpyridine is immobilized on a carbon nitride support.
Claims13
A heterogeneous catalyst represented by Rh/C3N4, used for preparing acetic acid through a methanol carbonylation reaction using carbon monoxide and configured such that a rhodium complex comprising a rhodium compound and 3-benzoylpyridine complexed with each other is immobilized as an active material on a carbon nitride support.
A method of preparing a heterogeneous catalyst, comprising:
- (S1) preparing a carbon nitride support by heating a melamine resin serving as a carbon source to 500 to 550° C. in a nitrogen atmosphere;
- (S2) preparing a rhodium complex by reacting a rhodium compound with 3-benzoylpyridine;
- and
- (S3) preparing a heterogeneous catalyst represented by Rh/C3N4 by immobilizing, on the carbon nitride support prepared in (S1), the rhodium complex prepared in (S2).
