【Daily Question】Chemical Engineering Principles 550: Extraction (April 12)
Thread Content
This post was last edited by “Back to Cambridge” on April 12, 2017, at 07:55. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Engineering Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active support~~~ Replies to the “Question of the Day” activity can be viewed directly**; the thread will be closed after 1 day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer: The extraction process is _______________________________. The process of adding a solvent to a mixture to transfer the solute from the original solution into the solvent.
Separate mixtures by utilizing the different solubilities of components in the solvent
The process of adding a solvent to a mixture to transfer the solute from the original solution into the solvent.
It refers to the transfer of a compound from one solvent to another by taking advantage of the difference in its solubility or distribution coefficient in two immiscible (or slightly soluble) solvents.
A method for separating and purifying substances based on the differences in their solubility and distribution coefficients in two different solvents.
The compound is transferred from one solvent to another by taking advantage of the difference in its solubility or distribution coefficient in two immiscible (or slightly soluble) solvents.
1. Check whether the testing instrument is leaking. 2. Pour in the reagents. 3. Extract and shake. 4. Let it stand to allow separation of layers. 5. Open the upper plug, rotate the piston to allow the lower layer of solution to flow into another beaker from below, then close the piston again to allow the upper layer of solution to flow into another beaker from the top.
The unit operation for separating mixtures by taking advantage of the different solubilities of components in the solvent
The process of adding a solvent to a mixture to transfer the solute from the original solution into the solvent.
By taking advantage of the different distribution patterns of various components in the solution between the two liquid phases, separation, enrichment, and purification are achieved through interphase transfer.
