particles. Finally, the powder was collected by filtration through a 0.2 μm polycarbonate membrane and washed with distilled water until the pH of the filtrate was neutral and dried at 80 °C overnight. RamanAD/AGratio=4.85. TGA (air) mass loss peak 615 °C, residue remaining=0...
A carbonylation process for making acetic acid uses a metallic co-catalyst composition effective as a rhodium stabilizer and rate promoter at molar ratios of metal/rhodium of from about 0.5 to 30. A preferred process includes: (a) reacting methanol with a carbon monoxide feedstock in a rhodium-...
