How is Acetic acid manufactured and what is its chemical nature

[From: ] [author: ] [Date: 11-06-13] [Hit: ]
carbon monoxide combine with a Rhodium based catalyst to yieldacetic acid.Briefly,(iv) MeCO-Rh-I which undergoes reductive elimination to yield MeCOI (acetyl iodide) which is hydrolysed under the conditions to yield MeCOOH and giving back HI.Acetic acid is a colorless, weak monobasic organic acid: CH3COOH; pKa ~ 4.75 having the smell of pungent vinegar.......
Acetic acid is produced in several ways, one of them is the Monsanto Process:

Methanol, hydriodic acid, carbon monoxide combine with a Rhodium based catalyst to yield acetic acid.
Briefly, (i) CH3OH reacts with HI to produce MeI
(ii) MeI adds oxidatively to Rh giving Me-Rh-I (other ligands on Rh not shown for simplicity);
(iii) this is followed by CO uptake and insertion and finally
(iv) MeCO-Rh-I which undergoes reductive elimination to yield MeCOI (acetyl iodide) which is hydrolysed under the conditions to yield MeCOOH and giving back HI.

Acetic acid is a colorless, weak monobasic organic acid: CH3COOH; pKa ~ 4.75 having the smell of pungent vinegar.
