What is an example of solvent extraction?
Examples of solvent extraction are the extraction of uranium and plutonium salts from solution in nitric acid in nuclear fuel reprocessing using kerosene as solvent, and the extraction of benzene from reformed naphtha using sulfolane as solvent.
What is reflux extraction method?
Reflux is a technique involving the condensation of vapors and the return of this condensate to the system from which it originated. It is used in industrial and laboratory distillations. It is also used in chemistry to supply energy to reactions over a long period of time.
Why is reflux used in distillation?
The purpose of reflux is to provide down-flowing liquid throughout the rectification section to contact with the up-flowing vapor in order to achieve stage-by-stage equilibrium heat and mass transfer and, hence, purification of the top product.
What are the main differences between reflux and soxhlet extraction?
The purpose is different. A normal refluxing apparatus consists only of a flask and cooling above (so fumes are collected while boiling and you can keep the amount of solvent constant). Soxhlet extraction on the other hand is for separating parts that are soluble in a solvent.
What is an example of extraction?
Extraction is the process of selectively removing a compound of interest from a mixture using a solvent. Making tea is a good example of extraction. Water is placed in contact with tea bags and the “tea” is extracted from the tea leaves into the water.
What is difference between reflux and distillation?
Reflux is a technique that involves the condensation of vapors which are then returned back to the sample. The main difference between reflux and distillation is that reflux method is used to complete a certain chemical reaction whereas distillation is used to separate components in a mixture.
Which solvent is used in Soxhlet extraction?
Soxhlet extraction is performed with different solvent mixtures such as hexane/dichloromethane, dichloromethane/light petroleum, cyclohexane/acetone or hexane/acetone, or even methanol, depending on the nature of the sample and the pesticides covered in the analytical method.
