Helo, reders welcome to “textilesgreen.in” today I m going to explain about how to convert Nitrobenzene to benzoic acid.

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 banzoic 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.

How to Convert Nitrobenzene to benzoic acid

First of all, Nitrobenzene (C6H5NO2) is react with the presence of Sn/HCl. Then aniline is formed.

C6H5-NO2 _sn/HCl – C6H5NH2

(Nitrobenzene) (Aniline)

Now, Aniline is again react with the presence of NaNO2/HCl. Then it give Diazonium Chloride as a product.

C6H5-NH2 _NaNO2/HCl – C6H5N2Cl

(Aniline) (Diazonium Chloride)

then, Diazonium Chloride is also react with the presence of H3PO2 then benzene is formed.

C6H5-N2Cl _H3PO2 – C6H6

(diazonium chloride) (benzene)

Then benzene is gain react with the presence of CH3-Cl (AlCl3) then C6H5CH3 is formed.

C6H6 _CH3-Cl/AlCl3 – C6H5CH3

And now, C6H5CH3 is react with the presence of KMNO4 then finely (C6H5COOH) benzoic acid is formed.

C6H5CH3 _KMNO4 – C6H5COOH

(Benzoic acid)

you can understand properly with the help of following process.

These are the conversion of nitrobenzene to benzoic acid with the help of flow chart.

So, see carefully and you got good idea for for preparation of benzoic acid.

• Benzoic acid has colourless solid product.

• it is insoluble in water.

• But it is soluble in benzene and alcohals.
