Caffeine Crystals and Coffee Chemistry!


Crystals of caffeine are extracted from coffee in this episode of Chemistry in Context. Techniques used include, solid-liquid extraction, liquid-liquid extraction, filtration, sublimation, and re crystallization. We also could have used TLC (thin layer chromatography) to examine the purity of the product – but this will be used in a different video.
