Extraction of Caffeine from Tea DESS Dichloromethane also known as methylene chloride, is an organochlorine compound with the formula CH₂Cl₂. It is a colorless, volatile liquid that has a sweet, chloroform-like odor. It is widely used as a solvent in chemical research and manufacturing due to its effectiveness in dissolving various substances. Ethyl acetate CH3CO2CH2CH3, simplified to C4H8O2 is a colorless, flammable liquid with a sweet smell, often compared to pear drops. It is primarily used as a solvent in various industries, including adhesives, paints, and coatings. Chemically, it is the ester of ethanol and acetic acid, and over 1 million tons are produced globally each year. Sodium carbonate with the formula Na₂CO₃, is an inorganic compound commonly known as soda ash. It appears as a white, odourless, water-soluble salt and can come in various hydrates. used in various applications, including glassmaking, as a cleaning agent, and in water softening. Sodium sulfate with the chemical formula Na2SO4, is a white crystalline solid. It is known for its use in various industries including glass manufacturing, detergents, and as a drying agent. The molecular weight of sodium sulfate is approximately 142.04 g/mol. Description: An anhydrous powder is a substance that contains no water. In the context of food and pharmaceuticals, anhydrous powders are often used for stability, easier transportation, and to enhance the formulation of products like vitamins and medications. For example, Dicalcium Phosphate Anhydrous is commonly used in chewable multivitamins and vitamin premixes.  Melting and Boiling Point NE Naphthalene is an organic compound with the chemical formula C10H8. It appears as a white crystalline solid with a strong odor similar to that of coal tar. Naphthalene is denser than water and insoluble in it. It is produced from crude oil or coal tar and can also be formed during the combustion of organic materials, making it present in sources such as cigarette smoke and car exhaust.
