Abstract

Quantitative studies on the bromination of resacetophenone showed that the reaction was slow and progressive and its magnitude depended primarily on the amount of bromate initially added in excess of the theoretical equivalent so that reproducible results could not be obtained directly by Koppeschaar’s method. However, on plotting the volume of bromate initially added against the excess found by titration, a linear graph was obtained which on extrapolation to zero excess gave the value of bromate equivalent to di-bromination of the ketone present in solution. The estimated maximum error involved was of the order of 5%.
