What is the purpose of the following in the experiment of Synthesis of Methyl Salicylate

1. Phosphoric Acid

2. Methyl Anthranilate

3. Sodium Nitrite

4. Diethyl Ether

5. Nitrogen

what is the reaction scheme

1. Phosphoric Acid : Catalyst

2. Methyl Anthranilate : Reactive

3. Sodium Nitrite : Reactive

4. Diethyl Ether : Solvent and reactant

5. Nitrogen : Sub-product

Explanation:

The phosphoric acid is used as a catalyst for the reaction, the methyl anthranilate will react with the sodium nitrite to produce methyl salicylate, along with the diethyl ether and the nitrogen is a sub-product of the reaction.
