Quantative Determination of Aromatic Phenols with NBSA Reagent
Journal Title: IOSR Journal of Applied Chemistry (IOSR-JAC) - Year 2018, Vol 11, Issue 2
Abstract
An accurate method has been described for determination of Aromatic phenols & its derivatives at micro scale using N-bromosaccharin as brominating & oxidizing agent. A known volume of sample solution of Aromatic phenols was treated with excess of N-bromosaccharin. After the reaction was complete the unreacted N- bromosaccharin was determined by titrating against standard sodium thiosulphate solution using starch indicator. A blank Experiment was also run under identical condition without the sample. The method is simple, quick, convenient and accurate and performed in ordinary laboratory condition without using any sophisticated instruments. The precision & accuracy was within ±1%.
