Ether extract
WebA third ether extraction of the water should take out 80% of the remaining 4%, thus leaving less than 1% of your material left in the water layer. Combine all the ether extracts, dry/concentrate, and you should get 99% yield. • Example 2: Suppose you are trying to use aqueous base to extract a carboxylic acid from a WebThe extraction tube is connected to suction by a two-way stopcock, and the stem of the extraction tube is connected to a preweighed Erlenmeyer flask. The extraction tube is filled up to two-thirds capacity by petroleum ether. After thorough mixing, the ether phase is separated by standing, and drained into the Erlenmeyer flask by suction.
