Aspirin synthesis may also include an additional step, in which wintergreen oil (methyl salicylate) is converted into salicylic acid (figure 2) this helps students to gain an understanding about multi-step synthesis and the idea of transforming a naturally occurring substance into a therapeutically valued. Synthesis salicylic acid (precursor to aspirin) from methyl salicylate (winter green oil) vs from benzene does production from 1 yield a different product than product from 2 no they are the same what is wintergreen oil methyl salicylate natural product (benzene (petroleum byproduct) is. Synthesis description for preparation of methyl salicylate (wintergreen oil) a mixture of 304 g of salicylic acid (02 mole), 70 ml of methyl alcohol, and 7 ml of concentrated sulfuric the washing with bicarbonate is repeated until no precipitate of salicylic acid forms on acidification of the aqueous layer. Introduction the purpose of the experiment is to convert oil of wintergreen into salicylic acid by a base-catalyzed hydrolysis reaction salicylic acid is a white, crystalline compound it is commonly used for the removal of warts from the skin.

A student researched lab analysis about the synthesis of salicylic acid from wintergreen oil my yield for the production of salicylic acid was 569% this was due majorly for the fact that the filteration system on many of the suction faucets did not work, making for repeated trials while losing. Salicylic acid (from latin salix, willow tree) is a lipophilic monohydroxybenzoic acid, a type of phenolic acid, and a beta hydroxy acid (bha) it has the formula c7h6o3 this colorless crystalline organic acid is widely used in organic synthesis and functions as a plant hormone. Both syntheses have salicylic acid on the reactants side, however differ in the second reactant that 'esterifies' the salicylic acid this is a vital process whereas in the creation of the oil of wintergreen, a lone pair of electrons on the oxygen in methanol attacks the carboxylic acid oxygen on the salicylic. Synthesis of aspirin from salicylic acid 4 risk assessment an additional step may be added to the synthesis of aspirin: conversion of oil of wintergreen (methyl salicylate) to salicylic acid (figure 2) this serves as an introduction to multi-step synthesis and the concept of converting a naturally. In the lab, it was apparent that all the students were able to use the air condenser and all other glassware used in the experiment the students also learned how to create salicylic acid from methyl salicylate by the use of refluxing and filtration one change that should be made to this lab is to.
We take a bottle of oil of wintergreen (methyl salicylate) and hydrolyse this under alkaline conditions to form salicylic acid we then purify the product and run some tests.
