| abstract |
The present invention relates to a heterogeneous catalyst for the production of acetic acid by methanol carbonylation, characterized in that a rhodium complex ion is ionically bonded to an insoluble catalyst support having a quaternary pyridine group alone or a mixture of acetate groups grafted onto the surface of a fluoropolymer According to the present invention, it is possible to easily design a fixed bed bubble column reactor and to eliminate the need for a special apparatus for separating the catalyst, it is possible to reduce the manufacturing cost of the apparatus and simplify the process, There are advantages. |
