Description
Diet coke was extracted into methylene chloride. A TLC was performed with no significant results. A sample of the extraction was then freeze dried over the course of 2 weeks. The sample was then rehydrated and extracted into methylene chloride again. A GCMS was taken of the initial extraction and the rehydrated extraction to compare the differences in composition. Initial results show that benzoic acid and caffeine stand out as present in both before and after freeze drying. Additional results including differences in the spectra are being analyzed and will be discussed.
