You will have to perform all the steps necessary to separate your assigned compound from its impurities and prove through analysis (melting point, boiling point (if applicable), NMR, IR and Rf-values (if applicable)) that your compound is pure: An organic student was trying to purify acetaminophen from Advil but the extraction using dichloromethane yielded a mixture of caffeine and acetaminophen. Purify the acetaminophen. Provide data to show that your compound is pure. Materials Available to you: Solvents: acetone, ethanol, methanol,...

2. For each solvent, indicate if it is miscible with each other solvent. If it is miscible, put an "M" in the box If it is not miscible, put and "X" in the box. methylene chloride diethyl ether acetone chloroform ethyl acetate water methylene chloride ethyl acetate diethyl ether chloroform 3.

You will apply what you have learned earlier in the semester when performing the Acid-Base Extraction experiment to perform a different separation: that of an organic neutral compound and organic base. You will also need to purify and characterize these compounds. You will have one lab period to execute your plan for separating the assigned mixture given below. There will be a 1:1 (by mass) mixture placed in the lab: 1,4-dichlorobenzene/ethyl 4-aminobenzoate. You will take approximately 1 g of your...

I need to write out a procedure for extraction and recrystallization of a 1:1 (by mass) mixture of 1,4-dichlorobenzene/ethyl 4-aminobenzoate. So far, I have that I am starting with extraction using 1 g. of the mixture and dissolving it in about 15mL of diethyl ether. Then I am putting it in a separatory flask and adding 15mL of 1M HCl to get layers. To the organic layer, I will add sodium sulfate and put in rotovap to get a solid....
