Procedure
6mls of concentrated sulfuric acid were dispensed into Erlenmeyer flask. Cooled to 0˚C in
an ice filled bucket, 2mls of methyl benzoate are added. To create a nitric – sulfuric
acid mixture, 1.4mls of concentrated nitric acid were added into same Erlenmeyer flask that
contained the sulphuric acid. This was then cooled to temperature not exceeding 0˚C and 10˚C in an ice bath. Sulfuric-nitric acid mixture was then added drop-wise to the cooled
methyl benzoate-sulfuric acid mixture; swirling regularly on addition and maintaining cool
temperatures ranging between 5˚C – 15˚C. The resulting mixture was then warmed to room
temperature. After a 15-minutes stay at room temperature, 50g of cracked ice were poured in a
250mL beaker. This resulted to formation of a precipitate. Suction filtration was used to separate
solid product, by sporadic use of water wash. A solid product collected was put in a beaker and
left to dry for a 7 days. It was then dried, weighed and separated into two, one for melting point
measurement and the other for TLC analysis. The remaining produ…
