So we have 2 compounds, a neutral compound and a weakly basic compound. How do we perform liquid-liquid extraction?
|
Both of these compounds are soluble in diethyl ether, but when aqueous HCl is added to an ethereal solution of the two
|
|
So we have 2 compounds, a neutral compound and a weakly basic compound. How do we perform liquid-liquid extraction?
|
The weakly basic one is converted to an ionic salt, whereas the neutral compound is unaffected
|
|
So we have 2 compounds, a neutral compound and a weakly basic compound. How do we perform liquid-liquid extraction?
|
Ionic compounds are usually more soluble in water than they are in diethyl ether; consequently this salt goes into aqueous layer
|
|
So we have 2 compounds, a neutral compound and a weakly basic compound. How do we perform liquid-liquid extraction?
|
After the separation, the weakly basic compound is regenerated by adding a base, and is extracted from aqueous solution by ether
|
|
What temperature should all extractions be done at?
|
At room temperature. It is dangerous to extract a warm solution
|

|
What is the max volume RB flasks should be?
|
RB flasks should never be more than 1/2 full. If we have too much solution, put some in RB evaporate it, then add rest of it into same flask
|
|
Why do we add 6M NaOH to the salt of base fraction?
|
We add it to regenerate our base. We test if we regenerated it by using a litmus test.
