How is benzocaine synthesized industrially from p-nitrobenzoic acid?

Principle: In step 1 common reduction of aromatic para-nitrobenzoic acid by tin and hydrochloric acid to para-aminobenzoic acid and in step 2 esterification of para-aminobenzoic acid by sulphuric acid and ethanol to benzocaine occurring called Fischer esterification.

What is principle of synthesis of benzocaine?

The classic, optimal way of benzocaine synthesis is the reduction of the nitro group of the ethyl ester of 4-nitrobenzoic acid to benzocaine by hydrogen, which generates directly in the reaction medium by the reaction of iron filings with dilute acids [24–26].

How do you get 4-nitrobenzoic acid?

Production. 4-Nitrobenzoic acid is prepared by oxidation of 4-nitrotoluene using oxygen or dichromate as oxidants. Alternatively, it has been prepared by nitration of polystyrene followed by oxidation of the alkyl substituent.

Is nitrobenzoic acid acidic?

Nitrobenzoic acids are derivatives of benzoic acid. Two are commercially important. They are about ten times more acidic than the parent benzoic acid. Nitrobenzoic acid can be prepared through the oxidation of styrene in boiling nitric acid.

Is 4 nitrobenzoic acid aromatic?

ChEBI Name	4-nitrobenzoic acid
Definition	A nitrobenzoic acid having the nitro group at the 4-position.

Why would 4 nitrobenzoic acid have a pKa greater than 2 nitrobenzoic acid?

Detailed Answer :As 4-nitrobenzoic acid contains –NO2 group which is an electron withdrawing group resulting in higher acidity than benzoic acid. Greater is the acidic character lower is the pKa value.

Is 4 nitrobenzoic acid strong or weak?

4-Nitrobenzoic acid is a stronger acid because the nitro group makes the aromatic ring unstable.

Why is 4 nitrobenzoic acid stronger than benzoic acid?

This is due to. direct resonance interaction between-NO2and-COOH groups. -NO2 group generates a strong-electron withdrawing inductive effect due to positive charge on meta position to -COOH group. …

What are the environmental impacts of 4-Nitrobenzoic acid?

4-Nitrobenzoic acid’s production and use in manufacturing intermediates, reagent for alkaloids and thorium, and in the production of pharmaceuticals and dyes may result in its release to the environment through various waste streams.

What is the KOC value of 4-Nitrobenzoic acid?

The Koc of 4-nitrobenzoic acid is estimated as 250 (SRC), using a log Kow of 1.89 (1) and a regression-derived equation (2). According to a classification scheme (3), this estimated Koc value suggests that 4-nitrobenzoic acid is expected to have moderate mobility in soil.
