To isolate caffeine from various substances requires different methods based on the establishment of the solution it is being extracted from. High pressure process is a new method that extracts caffeine from tea leaves and has been shown to pass an payoff such as shorter extraction times (Nature.com).

Methods When the watchful tea solution has cooled down to room temperature, polish off 10-mL of tea into two centrifuge tubes. Add 3-mL of methylene chloride and 0.5g of sodium bicarbonate to each centrifuge tube. Shake...If you want to get a full essay, order it on our website: OrderEssay.net
