National Renewable Energy Laboratory (NREL) Home Page | NREL procedure is original restates the purpose of the lab and The theoretical yield of the reaction was 1.54 g, The % yield was calculated and found to be 39.81%. Reaction table starting with 1 of acetaminophen. Experiment 7- Williamson Ether Synthesis: The Synthesis of Phenacetin from Acetaminophen used to verify and prove the con- behind the lab, including a brief The phenolic hydrogen goes to deprotonation because it is acidic hydrogen. While the Theoretical melting point was obtained at 133C-136C. Tricia Glidewell, Marist School, Atlanta, Georgia. ####### Table 2. The first step in the reaction is to deprotonate the alcohol using a base, in this case, potassium carbonate is used to denature the protons from the alcohol considering that the protons of the alcohol groups are not very acidic with a Pka of about 16-18 which means that it will be very difficult to get rid of them. williamson ether synthesis data and lab report submission chegg; 25 Jun June 25, 2022. 00 Comments Please sign inor registerto post comments.
