Aspirin, the common household treatment for issues ranging from headaches to heart disease, is made from a relatively simple process, one that year 13 students are capable of replicating. Aspirin remains one of the most studied drugs in the world, admired by many scientists and being used from as early as 1890s in its acid form and even earlier in the form of leaves.
I had the opportunity to attend a workshop at King’s College London with the Chemistry department led by Dr Helen Coulshed. After being given the iconic scientists blue coats and goggles we were given a hand-out of what we had to do. There were four procedures that we needed to carry out and each once lasted around 30 to 40 minutes, we used ingredients green oil, ethanol, hydrochloric acid and sulphuric acid. I found the stages very interesting as well as the filtering processes and the equipment we used. King’s College has particularly advanced equipment which aided our process as did their helpful ambassadors who were able to offer assistance. Furthermore I enjoyed the process of crystallisation with the use of filtration, especially having to use the vacuum to help with the process. It was also great to use spectroscopy, something that I had been accustomed to on paper and it was great to see King’s College equipment help bring it to real life
Overall the experience reaffirmed my ambitions to study at university especially due the lab environment as it was essential in preparing me for university. It was surprising to see that a drug such as aspirin was relatively easy to make and it was a unique opportunity that was given to me in order to do so. To improve I would write down my notes in a more professional manner.
