Because the organic layer is immiscible with water, it can be separated, and the solvent Determine the weight of the pure product and then calculate the weight percent of caffeine in tea based on the initial amount of tea used. Covers distillation, sublimation, and melting point analysis. Caffeine melts at 238°C Learn caffeine extraction & purification techniques in this college chemistry lab manual. Tea leaves contain gallic acid, tannins and a number of other colo boiling water may extracted quite easily into hot water. In this video, an introduction to extraction of caffeine from tea bags will be discussed. Includes procedure, safety, report guidance, and mass spectrometry.
