The process of isolating an organic compound from its aqueous solution by shaking it with solvent is known as solvent extraction. It is also called differential extraction.
In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
Selecting the most suitable solvent for your extraction process is crucial for optimal results. Consider the following factors when making your choice: Solvency: Ideally, the solvent should dissolve the target compound(s) …
The solvent extraction (SX) process is a hydrometallurgical procedure in which metals, such as copper, platinum, gold, cobalt, nickel, zinc, or uranium, are recovered through the use of organic extractants. To separate the organic phase from the aqueous phase of the solvent, they are stored in settlers. Some of the impurities in the system ...
