Methyl benzoate is a food additive permitted for direct addition to food for human consumption as a synthetic flavoring substance and adjuvant in accordance with the following conditions: a) they are used in the minimum quantity required to produce their intended effect, and otherwise in accordance with all the principles of good manufacturing. Nitration of methyl benzoate this reaction is another example of electrophilic aromatic substitution (s e ar) in today's experiment the reactant is the ester, methyl benzoate and the electrophile is the. Nitration of acetaniline instead of methyl benzoate is explained by the fact that the amide substituent with the phenyl bonded to the nitrogen is an electron-donating group and is moderately activating towards electrophilic aromatic substituion, whereas the ester group with the phenyl on the carbonyl carbon is an electron withdrawing group and. After the nitration reaction of methyl benzoate, why is product poured onto ice instead of water exothermic/endothermic -the reaction between h2so4/hno3 is exothermic, so splashing is less likely if the heat from disassociation is used to heat the ice.
