Nitration of methyl benzoate introduction: nitration is an example of an electrophile aromatic substitution reaction, where nitro (no2) group is being substituted for a hydrogen on an aromatic compound this is achieved by the formation of the nitronium ion by protonation of nitric acid from sulfuric acid.

Chapter 28: nitration of methyl benzoate purpose: in this experiment we are to take a cold solution of an aromatic ester that is first dissolved in sulfuric acid and is then reacted with nitric acid this is a highly exothermic reaction and is kept under control by means of cooling after which the mixture is poured onto ice. The nitration of methyl benzoate is a typical electrophilic substitution reaction what is occurring in this experiment the methyl benzoate reacts with the sulfuric acid which protonates it creating a positive charge on the oxygen.

Nitration of methyl benzoate bachelor of science in human biology college of science, de la salle university - dasmariñas abstract _____ aromatic hydrocarbons are electron rich and are stable because it has a benzene ring.

The methyl benzoate reacts with the sulfuric acid which protonates it creating a positive charge on the oxygen the reaction between nitric acid and sulfuric acid creates the nitronium ion the nitronium ion then reacts with the + charge on the arenium ion, and the nitro group is added onto the benzene ring at the meta position.

Aerobic: methyl benzoate, present at 28 mg/l in activated sewage sludge, achieved 62% biodegradation in 29 days using a modified sturm test measuring carbon dioxide evolution and is considered readily biodegradable(1. Question 1: amount of methyl benzoate _____ ml, _____ g, _____ mol question 2: amount of concentrated nitric acid (16 m) _____ ml, _____ mol question 3: amount of concentrated sulfuric acid (18 m) _____ ml, _____ mol question 4: show your calculations. This is the mechanisms of for nitration of methyl benzoate: result and observation melting point for 1st= 75˚c - 78˚c 2nd= 76˚c - 78˚c from the literature boling point which is melting point for methyl m-nitrobenzoate whic is 78-80˚c, we can conclude that the product that we get is methyl m-nitrobenzoate.
