Question

How can we convert Acetophenone to Benzoic acid?

Answer 1

Hint: We know that Acetophenone is the natural compound with the equation \[{C_6}{H_5}C\left( O \right)C{H_3}\] (additionally addressed by the pseudo element images \[PhAc\] or\[BzMe\]). It is the easiest sweet-smelling ketone. This boring, thick fluid is an antecedent to valuable saps and scents. Benzoic acid is a white solid with the chemical formula $C_6H_5COOH$. 
Acetophenone is converted into Benzoic acid, mainly in two steps, first includes in the presence of alkaline medium and second is on acid hydrolysis. 

Complete answer:
Acetophenone is recuperated as a result of the oxidation of ethylbenzene to ethylbenzene hydroperoxide. Ethylbenzene hydroperoxide is middle in the business creation of propylene oxide through the propylene oxide - styrene co-item process. Ethylbenzene hydroperoxide is basically changed over to 1-phenylethanol (α-methyl benzyl liquor) in the process with a limited quantity of side-effect acetophenone. Acetophenone is recuperated or hydrogenated to 1-phenylethanol which is then dried out to deliver styrene.
Acetophenone can be changed over into benzoic acid as follows
Step-1: Conversion of acetophenone into ethyl benzene.

 

Acetophenone is decreased by Zinc amalgam and conc. $HCl$ to shape ethyl benzene.
Step-2: Conversion of ethyl benzene into benzoic acid.

Ethyl benzene is oxidized by basic $KMn{O_4}$ to frame potassium benzoate, which on acid hydrolysis gives benzoic acid.

Note:
We have to know that benzoic acid is a dull strong and the most straightforward sweet-smelling carboxylic corrosive. The name is derived from gum benzoic, which was for quite a while its lone source. Benzoic corrosive happens normally in numerous plants and fills in as middle in the biosynthesis of numerous optional metabolites. Benzoic corrosives are utilized as food additives. Benzoic corrosive is a significant antecedent for the mechanical union of numerous other natural substances. The salts and esters of benzoic corrosives are known as benzoates.
