extraction as a separation technique

EXTRACTION: A SEPARATION AND PURIFICATION

2016-7-6  Today’s experiment focuses on the separation technique called extraction. There are manyextractions that lead to chemicals that are extremely important in our lives. Taxol is a very minor constituentof the bark of the Pacific yew but it has valuable chemotherapeutic properties for the treatment of ovarian andbreast cancer. Starting with about 3000 trees, extraction is part of the process that produces 2 pounds of thedrug. Coffee contains the chemical caffeine, a temporary stimulant. Some people drink the coffee for thestimulant but others like the taste and do not want the caffeine. Two of the common ways of removing thecaffeine involve either extraction

2017-11-12  the solid, is called extraction. Crystallisation is a sophisticated form of evaporation technique in which crystals of the solute are encouraged to develop during the process of “dissolving out” from the solution as the solvent evaporates. Magnetic Separation This method of separation is exemplified by the separation of iron filings.

Difference Between Separation and Extraction

Key Difference: Extraction is a method used for the separation of organic compound from a mixture of compound. This technique selectively dissolves one or more compounds into an appropriate solvent. Whereas separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures.
