Ultimately, it will take the melting point of phenacetin. While the Theoretical melting point was obtained at 133C-136C. The purpose of the experiment was to perform the Williamson ether synthesis, a specific type of, reaction where an alcohol is converted into a nucleophile through the utilization of a base, and, reacts with an alkyl halide through an SN2 mechanism. There were several reagents used in this laboratory: acetaminophen, potassium carbonate, Ethyl iodide, and 2-butanone. Data procedure contains Specifically, we will prepare alkyl aryl ethers via an SN2 reaction of alkyl halides with substituted phenoxide anions. - Physical Hazard: We extracted the organic layer with 10 mL of brine, and transferred the organic layer to a clean dry Explanations for OH OTI.
