Abstract

Promotion Effect of Hydrogen on Vapor Phase Carbonylation of Methanol over Nickel on Active Carbon Catalyst

Abstract In the vapor phase carbonylation of methanol by carbon monoxide on a nickel on active carbon catalyst, co-existence of hydrogen greatly enhanced the rate of acetic acid production but with a slight increase in methane formation.

Formation of iridium carbonyl complex in NaY zeolite

The structure of iridium carbonyl complexes trapped within the zeolite cavities and the reactivity of these species towards the methanol carbonylation have been investigated. Ir(NH 3) 5Cl 2+-exchanged NaY zeolite upon thermal decomposition is converted into an Ir(OH) x species. The carbonylation of iridium was followed by quantitative measurement of the 12CO uptake, infrared spectra of the reaction with 12CO, 13CO, and a mixture of 12CO 13CO. Ir(I)(CO) 3 was found to be very active and selective for the vapor phase carbonylation of methanol at atmospheric pressure in the presence of methyl iodide.

Kinetics of the catalytic vapor phase carbonylation of methanol to acetic acid

The reaction kinetics have been established for the low pressure vapor phase catalytic carbonylation of methanol to acetic acid using a solid supported rhodium complex catalyst. The catalyst is a heterogeneous analog of a previously developed homogeneous liquid phase catalyst system based upon a rhodium complex and an iodide promoter. Significantly, the reaction order dependencies are identical to those established for the liquid phase reaction (i.e., first order in iodide and independent of methanol and carbon monoxide concentrations). This suggests that in spite of the obvious physical differences between these heterogeneous and homogeneous catalysts, a similar chemical reaction mechanism is probably operative.
