2015年8月17日 3. Importance of the process: The Solvent Extraction(S.E.) process was first developed as a tool of analytical chemistry. Every metallic element of the periodic table could be virtually separated by this process. Back in 1940’s , S.E. was primarily used to separate nuclear and rare earth elements. However, availability of inexpensive and effective reagents led to the

Solvent extraction is a separation method that uses an immiscible solvent to separate two-component or multi-component solutions. Solvent extraction is a simple and efficient method for recovering 2,3-BD from fermentation broth. It offers advantages such as solvent recovery and recycling, making it reliable and economically feasible.

Extraction of neutral compounds. If the desired organic compound is neutral (i.e. is neither acidic nor basic), the extraction sequence usually involves simply extracting with an organic solvent several times. Extraction of acidic compounds. If the desired compound is acidic, we can selectively deprotonate that compound by using an aqueous base.

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.
