carbonylation of methanol to acetic acid
What is methanol carbonylation to acetic acid?
Methanol carbonylation to acetic acid (AA) is a large-scale commodity chemical production process that requires homogeneous liquid-phase organometallic catalysts with corrosive halide-based cocatalysts to achieve high selectivity and activity.
What is methanol vapor-phase carbonylation?
Eastman Chemical Co patented in 2000 the vapor-phase carbonylation of methanol into acetic acid and methyl acetate using gold deposited on carbon or activated carbon (1% Au/C) in the presence of methyl iodide operating at 240 °C and 17 bar of CO/H 2 , . Their activity is close to that of iridium catalysts.
Can nickel/active carbon be used as a methanol carbonylation catalyst?
On the character of nickel/active carbon as methanol carbonylation catalyst Synthesis of acetic acid from methanol and carbon monoxide in the vapour phase in presence of nickel catalysts at high pressures Deactivation and regeneration of an activated carbon-supported nickel catalyst for methanol carbonylation in the vapor phase Catal.
Is methanol carbonylation the oldest reaction of homogeneous catalysis?
Conclusions Methanol carbonylation is one of the oldest reaction of homogeneous catalysis that was developed industrially, mainly because of stability issues associated with the heterogeneous systems.
