Answer 1

$\huge\bold{\mathbb{\purple{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$

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

Answer 2

Answer:

Industrial prepration of ethaonic acid (Quick vinegar method)

Explanation:

The industrial preparation of vinegar involves the fermentation of alcohol. In this method, a tank with holes at the bottom, to allow air-circulation. The tank is filled with wood shavings and mixed with ammonium sulphate. Ammonium sulphate is useful in increasing bacteria population. Then, 10% ethanol is added slowly to the tank from the above. Ethaonic acid is produced in the lowest portion of the tank by fermentation process. The ethanoic acid produced as a result is known as vinegar and the concentration of ethaonic acid in vinegar is 3-4%.

Pure ethanoic acid which is free from water is known as glacial acetic acid. It's boiling point is 118°.

To test whether ethanoic acid has been produced or not, sodium carbonate is added to the product obtained. If acid has been formed then carbon dioxide gas would be released with rapid bubbling.
