synthesis of detergent

3 pts.) When synthesizing the detergent you performed extractions at the end of the reaction. First you extracted various salts away from the detergent into a water layer (the detergent was in the butanol layer). After separating the water and butanol layers you then extracted the water layer with more butanol. What was the purpose of this extraction on the water layer?

Answer #1

The detergent has high solubility in the butanol layer. But it has some solubility in water layer. It is not completely water insoluble. After separating the water and butanol layers you then extracted the water layer with more butanol. This is to ensure that the amount of detergent that was remaining in water layer is also extracted into butanol layer.
