Acetic Acid is the product of the reaction between methanol and carbon monoxide at 185 °C and 27.5 bar pressure in a fluidized bed reactor with Rhodium containing complex catalyst and methyl iodide as promoter.
Acetic acid is used in many industrial processes for the production of substrates and it is often used as a chemical reagent for the production of a number of chemical compounds like acetic anhydride, ester, vinyl acetate monomer, vinegar, and many other polymeric materials.
Application:
- Latex in rubber industry
- Paint industry
- Silk and synthetic fibers
Acetic acid has been prepared on an industrial scale by air oxidation of acetaldehyde, by oxidation of ethanol (ethyl alcohol), and by oxidation of butane and butene. Today acetic acid is manufactured by a process developed by the chemical company Monsanto in the 1960s; it involves a rhodium-iodine catalyzed carbonylation of methanol (methyl alcohol).
