Year 12 Chemists creating Aspirin

It is that time of year again! The A level chemists are taking full advantage of the fact that Year 11 and 13 have now finished and are using the space in the science laboratories to spend the whole day doing practical work.

The day started with the Year 12 chemists making aspirin. They heated the reactants under reflux, a technique where prolonged heated reactions can be carried out without loss of substances to the environment. The synthesised aspirin was then purified by recrystallisation before the students analysed the purity of their product.

All a challenge on any day let alone on the hottest days of the year so far!
