Hydrolysis of methyl Salicylate Aim To pay off 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 kelvin oil utilise as a rubefacient in productive 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 use in organic synthesis and functions as a plant hormone. It is derived from the metabolism of salicin. It is best known for its use in anti-acne treatments.

[ 2] ebbing was a heating attend to whereby vapours from the reply motley 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 create 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. emptiness filtration occurs faster than gravity filtration by lowering the pressure in the flask, pulling the filtrate into the flask, speeding up the whole edge of filtra tion. It ensured 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 ensnare to purify the salicylic acid crystals as the first batch of crystals produced contained numerous contaminants such as Cl- from the acidification previously carried out, resulting in impure salicylic...
