Production pathways of acetic acid and versatile applications in food
This chapter reviews the current commercial processes for the synthesis of acetic acid to meet an ever-increasing global demand The chapter also gives insight |
In principle, acetic acid can be produced by the direct reaction of methane and carbon dioxide:(.
1) CH 4( g ) + CO 2( g ) ↔ CH 3 COOH ( g ) , Δ H° 298 K =+8.62 kJ/mol, Δ G° 298 K =+16.98 kJ/mol The large, positive value of the Gibbs free energy change shows that reaction (1) is very thermodynamically unfavorable.
How acetic acid is produced by synthetic method?
Acetic acid is mainly produced via chemical route which involves homogeneous as well as heterogeneous catalytic methods.
The carbonylation of methanol via Monsanto process is the most adapted route, which further evolved as Cavita process with a choice of catalysts and process intensification.
How do you synthesize acetic acid?
Most acetic acid is produced by methanol carbonylation.
In this process, methanol and carbon monoxide react to produce acetic acid according to the equation: The process involves iodomethane as an intermediate, and occurs in three steps.
A metal carbonyl catalyst is needed for the carbonylation (step 2).
How is acetic acid prepared?
Preparation of Acetic acid-CH3COOH
Here, a methyl iodide intermediate is generated from the reaction between methanol and hydrogen iodide.
This intermediate is then reacted with carbon monoxide and the resulting compound is treated with water to afford the acetic acid product.
