Hydrolysis of methyl group Salicylate Aim To get salicylic panelling via the hydrolysis of methyl salicylate under basic conditions. Introduction Methyl Salicylate is a colourless liquid at populate temperature is a naturally occurring compound found in pass color oil utilise as a rubefacient in buddy-buddy heating liniments and in small amounts as a seasoning agent at no more than 0.04%.[1] Salicylic acid is a colorless crystalline organic acid is widely utilize in organic synthesis and functions as a transplantation hormone. It is derived from the metabolism of salicin. It is best known for its use in anti-acne treatments.

[ 2] wane was a heating attend to whereby vapours from the reply compartmentalisation were condensed and returned to their original flask. This ensure that the reaction could be maintained at the boiling point of the declaration while the solvent was non lost to the atmosphere. This was an important rate in ensuring a higher(prenominal) yield of salicylic acid by ensuring that sodium salicylate, the compound organize after hydrolysis of NaOH was not poached off and lost as vapour. Suction filtration was used to collect the desired crystals for and in the recrystallisation procedure. vacuum filtration occurs faster than gravity filtration by lowering the pressure in the flask, pulling the filtrate into the flask, speeding up the whole evidence of filtration. It en! sured that crystals ere separated from water as much as possible, so that the crystals could dry faster and the melting points could be observed accurately in a shorter period of time. Recrystallisation was carried out in prepare to purify the salicylic acid crystals as the first batch of crystals produced contained many another(prenominal) contaminants such as Cl- from the acidification previously carried out, resulting in impure salicylic...
