It's a catalyst
Benzoate indicates a COO- group attached to the benzene ring. This is a deactivating group and deactivates the benzene ring as well as is a meta directing group. Hence, two products could form. 1. Monosubstitution - results in 3-nitromethylbenzoate 2. Disubstitution - results in 3,5-dinitromethylbenzoate
The reaction of methyl benzoate with dilute sulfuric acid generates benzoic acid and methanol as the main products.
181gMethyl Benzoate is 136gMethyl benzoate is when you replace one of the hydrogens with a group of NO2NO2 has a mass of= 46gadd this to the mass of the methyl benzoate then take away 1 which is mass of the hydrogen that was replaced
Check the book Macroscale and Microscale by Williamson and Masters. Go to the chapter entitled Nitration of Methyl Benzoate. The synthesis of 3-nitrobenzaldehyde/3-nitrobenzoic acid has the same procedure.
The best solvent for methyl benzoate is typically a non-polar solvent such as diethyl ether or dichloromethane. These solvents are effective in dissolving methyl benzoate due to its non-polar nature and facilitate its extraction and purification processes.

Methyl benzoate, an organic compound, is an ester. It is a colorless liquid that is not soluble in water and has a fruity smells. Some uses for methyl benzoate are as a solvent and a pesticide.

Sulfuric acid will turn red when methyl orange is added, indicating that the solution is highly acidic.
HCl is not used in the preparation of methyl m-nitrobenzoate because the presence of a strong acid like HCl can lead to unwanted side reactions, such as hydrolysis or nitration of other functional groups on the molecule. Instead, a milder acid catalyst like sulfuric acid is typically used in these types of reactions to promote the esterification process efficiently.
methyl parabenpropyl parabensodium benzoate
The ester formed from octyl benzoate is called octyl benzoate. It is formed when octanol reacts with benzoic acid in the presence of a catalyst. This ester is commonly used in cosmetics and personal care products as a fragrance ingredient or UV filter.
To prevent di-nitration of the methy benzoate because COOMe group attached to the aromatic ring is deacitvating, hence, plus the deactivating NO2 group, a higher temperature and more acidic condition would be required to add another NO2 to the 5th carbon of the aromatic ring of the methyl 3-nitrobenzoate
