The combat record of the Winged Hussars stands for itself. In 1577 a massive charge of this ultra-heavy cavalry unit smashed a German army from Danzig, blitzing into the teeth of a 12,000 man force and crushing them until all that remained was a well-trampled patch of red where the enemy army once used to be.
Dichloromethane is an organic compound with the formula CH2Cl2. This colorless, volatile liquid with a moderately sweet aroma is widely used as a solvent. Although it is not miscible with water, it is miscible with many organic solvents.
Thus, the dichloromethane extraction of a basic tea solution removes nearly pure caffeine, which has a slight green color from the chlorophyll impurity. Shanbhag Caffeine Extraction 2006 After the extraction procedure, the organic solution of dichloromethane and caffeine is dried with an anhydrous inorganic salt. Crude caffeine is recovered as a solid residue by evaporation of the dichloromethane. The solubility of caffeine in water at 20Â°C is 2.2 g per 100 mL, so there is no problem in keeping it in water solution while you filter off the spent tea leaves and calcium salts.
