Question

How do you convert methan to acetic acid?

Answer 1

The conversion of methane to acetic acid is currently carried
out in a three-step process
Methane is first reformed in a
heterogeneously catalyzed process that is energy- and capitalintensive
to produce synthesis gas, a mixture of CO and H2.
The CO and H2 then react at high pressure in a second step to
produce methanol, and finally, in the third step, acetic acid is
produced by homogeneous-phase carbonylation of methanol.
Because of the strong demand for acetic acid (3.1 million
tons/year by the plastics, textiles, paper, paints, and adhesives
industries, there is considerable interest in finding ways
to synthesize acetic acid directly from methane.

Sevaral studies have recently shown how this might be done. For example,
methane will undergo oxidative carbonylation in either water
or strong acid catalyzed by Rh or Cu cations, and the
carboxylation of methane has been demonstrated in both water
and strong acids using soluble V-based catalysts . A particularly
interesting approach for the direct synthesis of acetic


acid from methane who describe the oxidation of methane to acetic acid catalyzed
by Pd2+ cations in 96 wt% sulfuric acid. The only other products
observed are methyl bisulfate (a precursor to methanol)
and carbon dioxide. Whereas the selectivity to the liquid-phase
products is reported to be as high at 90%, Pd2+ is observed
to precipitate from solution as Pd-black, causing the reaction
to stop. In some case reproduces these observations and
showed that the addition of Cu2+ and O2 to the reaction mixture
enhances the yield of acetic acid without dramatically increasing
the yield of methyl bisulfate or decreasing the selectivity.
The aim of the present study was to investigate the effects
of CH4 and O2 partial pressure, temperature, and sulfuric acid
concentration on the synthesis of acetic acid and on the retention
of Pd2+ in solution. The pathways leading to the formation
of CO and CO2 were examined, as was the mechanism by
which the carboxylate group in CH3COOH is formed. A further
aim of this study was to identify the effects of reaction
conditions on the formation of sulfur-containing acids, such as
methanesulfonic acid, methane disulfonic acid, and sulfoacetic
acid
