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. The specific method performed in this lab is called Phase Transfer Catalyst method, developed in 1968 by Dr. Charles Starks.
