Caffeine from any source, be it tea leaves, guarana seeds, coffee beans or from a synthetic manufacturer, will always be the same chemical, otherwise it could not be called caffeine. From any source, caffeine will be C8H4N10O2, and will have the same properties.

Is Caffeine clear?
Pure caffeine is a water soluble white crystalline purine. Caffeine is found in its pure state only after being synthesized in a lab or extracted from certain plant or animal cells. Most commercially made caffeine is produced by decaffeination of coffee beans, although there are many other sources.
How caffeine is produced?
Caffeine is found in its pure state only after being synthesized in a lab or extracted from certain plant or animal cells. Most commercially made caffeine is produced by decaffeination of coffee beans, although there are many other sources. Synthetic caffeine can be manufactured in a lab, but the process is commercially impractical.
Is the caffeine in mountain dew a compound?
Yes, caffeine is an organic compound. The caffeine in mountain dew was extracted from coffee in the process of making decaffeinated coffee.
What criterion is used for the purity of a sample of caffeine?
The closer the melting point of the sample of the caffeine you have extracted, to the known melting point of pure caffeine, the more pure your sample is.
What purpose does dichlorometane in caffein extraction?
doesn't it allow the caffeine to migrate into solution which can be evaporated away just to leave the extracted caffeine?
What is separated from coffee?
When coffee is brewed, the coffee solids and the caffeine are extracted from the grounds into the water.
Why do we add potassium carbonate during caffeine extraction?
Tannins are neutralized by potassium carbonate, remain in the water solution and caffeine is easily extracted with methylene chloride.
Is caffeine the same type in coffee and tea?
Caffeine is a chemical that remains in the same form no matter what it's actual source is. So yes, the caffeine in tea and the caffeine in coffee is identical, but for it's concentration (the amount of it in the drink).
Do caffeine molecules have polar bonds?
According to edexcel mark scheme, caffeine has both London forces and permanent dipole forces.
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.
How caffein is decaffeinated?
There are a few different ways of removing caffeine, but often a solvent will be used to extract caffeine from the coffee bean while leaving all the other chemicals in tact. This is then repeated several times to extract even more caffeine. Other methods involve soaking of the beans to remove caffeine, and subsequently filtering the caffeine out of the water while keeping the beans and extracted coffee solids together.
