In this experiment‚ we used methyl benzoate from the last experiment with HNO3 and H2SO4 to synthesize methyl 3-nitrobenzoate. First we added methyl benzoate to 12 mL cooled conc. Sulfuric acid in a flask. In a separate flask‚ we made a solution of 4 mL conc. Sulfuric acid and 4 mL nitric acid and then added dropwise to the solution of methyl benzoate in an ice bath on a stir plate while maintaining the temperature of reaction between 5-15 °C. After the addition was complete we took the flask out

naturally occurring fats and oils are the fatty acid esters of glycerol. Esters with low molecular weight are commonly used as fragrances and found in essential oils and pheromones. Phosphoesters form the backbone of DNA molecules. Nitrate esters‚ such as nitro-glycerine‚ are known for their explosive properties‚ while polyesters are important plastics‚ with monomers linked by ester moieties. ------------------------------------------------- Structure & Bonding Esters contain a carbonyl centre‚ which
