Caffeine is commercially isolated primarily from coffee beans, tea leaves, and other plant sources through a process of extraction. The most common method involves using water or solvents like ethyl acetate or supercritical carbon dioxide to dissolve the caffeine, separating it from the plant material. Following extraction, the solution is filtered, and the caffeine is crystallized through evaporation or cooling. This process allows for the purification and concentration of caffeine for use in various products.

What was the name of the German chemist who isolated caffeine?
Friedrich Ferdinand Runge.
A student used 8.23g of tea leaves in the experiment and as much as 5wt of caffeine can be found in the tea leaves. how much caffeine in grams is expected to be isolated out assuming all the caffeine?
There is about 5% of caffeine by weight of the leaf material in tea plants, so 8.23g of tea should have 0.4115g of caffeine.
How is caffeine extracted from coffee beans?
Caffeine is extracted from coffee beans through a process called solvent extraction. The beans are soaked in a solvent, such as water or a chemical solvent, which helps to dissolve the caffeine. The solvent is then separated from the beans, and the caffeine is isolated and purified through further processing.
How are things caffeinated?
Caffeine is a substance that occurs naturally in many foodstuffs - usually it does not need to be "added". However caffeine can be isolated and added to other products in liquid form (most notably cola and sports drinks).
How do you remove caffeine from a mixture?
Caffeine is removed in factories using super critical fluid extraction. That uses carbon dioxide under pressure (as a liquid) to pull the caffeine out, which can then be evaporated off. Caffeine can be extracted in an laboratory by adjusting to the right pH, followed by extraction with an organic solvent like hexane.
What are some possible explanations to why melting point of your isolated caffeine was lower than the literature value?
Melting points should always be reported as a range. Maybe during purification process was not perfect, and there were impurities in the caffeine that were affecting the melting point. The melting point is depressed due to impurities in the sample. The caffeine is usually not 100% pure, maybe improper isolation procedure and also the impurity is likely solvent.
What was the first commerically available computer in the US?

What do you feed a sugar glider?
