Beginning of melting point range Harmful if swallowed Avoid release to the environment. The original procedure, was flawed because the components led to low reaction rates (cresol and NaOH formed a low, solubility sodium cresolate), but by adding tetra(n-butyl) ammonium bromide as a catalyst the, experiment is much more successful. Mole of Acetaminophen: (1.31g / 151.16 g/ mol) = 0.0086 mol, Mole of Ethyl iodide: (1.81g / 155.97 g/ mol) = 0.0116 mol, Phenacetin molecular weight: 179.22 g/mol, Theoretical Yield: (0.0086 mol x 179.22 g/mol) = 1.54 g, % Yield: (0.613 g / 1.54 g) x 100% = 39.81%.
