Extracting with ether
WebExtraction is the most common technique used to separate a desired organic product from a reaction mixture or to isolate an organic substance from its natural source. General … WebClomiphene isomers, in addition to metabolites, have been extracted using tert -butyl methyl ether (MTB) [ 21 ]. In a standard extraction, MTB (12 mL) was added to a 3 mL plasma sample in a screw-top centrifuge tube, and subjected to end-over-end rotation at 50 rpm for 30 minutes.
