Briefly explain how you would "extract the aqueous layer two times with 5-mL portions of methylene chloride."

Homework Answers

Answer #1

Liquid-liquid extraction

Take your aqueous reaction mixture (or aqueous layer containing the compound to be extracted) in a separatory funnel.

Add 5 ml portion of methylene chloride to it. Shake vigorously, and then let it stand for while so that the layers gets separated.

Remove the lower methylnene chloride layer.

Agan add 5 ml of methylene chloride and repeat the process.

Combine the two organic layers and this layer now has compound extracted from aqueous layer into it.

*Explain how the products were extracted with acid and base (explaining solubility in particular layers)* Phenyl acetate was reacted with anhydrous aluminium chloride. As soon as the HCl evolution subsided, the flask was heated for 1 hour. The flask was then allowed to cool and 100g of ice and 15ml of HCl was added. The mixture was then extracted with three 20ml portions of ether. The ether extracts were combined and the phenolic materials were extracted with two 50ml portions...

In an extraction experiment similar to your expt. 4, you attempt to separate 2-naphthol from cyclohexane, both of which are dissolved in ether. You attempt the separation by extracting the organic layer with a ̴5% NaOH (aq) solution (made by adding 5.00 g of NaOH to every 100 mL of water). Assuming that all of the base present in the aqueous solution reacts with the phenol during your extractions, what is the minimum volume of the aqueous NaOH solution needed...

So I did a experiment on extraction of caffeine. Here is the question, If your goal was to isolate as much caffeine from the aqueous layer as poassible, which of the two methods used in this lab would you use and why? We had 2 methods, first method was using 60 mL of CH2Cl2 to extract second method was using 20 mL of CH2Cl2 three times to extract (60 mL total). Now I know that the second method is better,...
