Hello, reders, today i m going to explain about how to convert Nitrobenzene to benzoic acid, benzoic acid to benzaldehyde, cumene to phenol, and aniline to phenol.
I have made this guide to help you out.
So, hold your seat and be with the end of guide.
So, you could get valuable information out of it.
Lets get started,

What is benzoic acid?
Benzoic acid is a white colour solid product. Formula of benzoic acid is C6H5COOH. benzoic acid occurs naturally in many plants. benzoic acid is windly used for manufacturing of many products such as perfumes and diffrent types of dyes etc. it is used in many source in textile industry. Sodium benzoate is a salt of benzoic acid. it is used as a PH adjuster and more.
Accomplish the following conversion
- Nitrobenzene to benzoic acid
- Cumene to Phenol
- Benzoic acid to benzaldehyde
- Nitrobenzene to aniline
- Aniline to phenol
Nitrobenzene to benzoic acid
This conversion is done with the help of two methods.
- Reaction Method
- Flow chart method.
Reaction Method,
First of all, nitrobenzene (C6H5NO2) is react with the presence of Sn/HCl. Then aniline is formed.
Now, aniline is again react with the presence of NaNO2/HCl. Then it give benzene diazonium Chloride as a product.
Then, benzene diazonium chloride is also react with the presence of H3PO2 then benzene is formed.
Then benzene is gain react with the presence of CH3-Cl (AlCl3) then C6H5CH3 is formed.
And now, finely,
Toluene (C6H5CH3) is react with the presence of KMNO4 then finely (C6H5COOH) benzoic acid is formed.
Nitrobenzene to benzoic acid Conversion with the help of flow chart.
Flow chart method,
You can understand properly with the help of following process.
So, see carefully and you got good idea for for preparation of benzoic acid.
2. Cumene to Phenol
First cumene is react with the presence of o2 air/sunlight then it is given cumene hydroxide as a product. You can see with the following reaction. and reaction is,
Again cumene hydroxide are done acidification with the presence of H+/h2O then it give phenol and acetone as a final product.
3. Benzoic acid to benzaldehyde
When benzoic acid is react with the presence of socl2 then it gives benzoyl chloride. in this reaction, acidic group is converted to chloride group. this type of reaction is called chlorination reaction. this reaction is as shown below.
And again benzoyl chloride is react with presence of h2/pd, Baso4 then it reduction is done and it gives benzaldehyde as a final product. this type of reaction is called Rosenmund’s reduction. This is also as shown below.
Thus, the hole of the reaction provided in a single step reaction. This is as given below.
4. Nitrobenzene to aniline
If you want do nitration of benzene with the presence of hno3/h2so4 then due to this reaction, nitrobenzene is formed. and this product is again react with the presence of sn/hcl then aniline is formed as a final product. these are called two step reaction. As shown in the reaction,
5. Aniline to phenol
Aniline is directly react with the mixture of nano2 and hcl and its give nacl + hno2. If aniline is also react with the presence of HNo2 then it give phenol as a final product. and N2 and H2O is also formed.
