The synthesis of an ether via the Williamson-ether reaction . more polar, which it makes acetaminophen more polar. 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. Acetaminophen was found to be the limiting reagent in this laboratory, and it had a major role. Safety Statements- contains little used instead of a secondary or tertiary alkyl halide.
