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, ethyl acetate, hexanes, diethylether, dichloromethane, chloroform-d for NMR
Aqueous Solutions: 3 M NaOH, 3 M HCl, 1 M NaHCO3 , saturated NaCl
Drying Agents: sodium sulfate, magnesium sulfate, calcium chloride

Introduction: The technique used to separate an organic compound from a mixture of compounds is called Extraction. Extraction process selectively dissolves one or more of the mixture compounds into a suitable solvent. The solution of these dissolved compounds is referred to as the Extract. Here the organic solvent dichloromethane is used to extract caffeine from an aqueous extract of tea leaves because caffeine is more soluble in dichloromethane (140 mg/ml) than it is in water (22 mg/ml). However, there are...
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...
Experiment Write Up Proposal You will write up a synthesis procedure for one reaction that could be potentially run in a face- to-face Chem 2321 lab session. Your proposal will include an introduction and procedure. The procedure will include step-by-step instructions for running the reaction (including reaction monitoring), work-up. (product isolation and purification), and analysis (characterization). You will need to include sample calculations for percent yield and provide sample spectra analysis. You must upload your proposal as a single document...
i need help with the postlab questions please Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
