Abstract
The room temperature liquid phase bromination of benzene with iodine as catalyst was chosen for the present study. These substances have no dipole moments but bromobenzene and hydrobromic acid have dipole moments of 1.52 and 0.78 D, respectively. The reaction mixture was poured into a quartz cell which was then closed tightly. Replicated microwave readings were taken at various time intervals, with intermittent shaking of the tube to ensure homogeneity. The reaction was stopped after 2.5 h by pouring the contents into excess potassium iodide. Total free halogen was estimated by titration against standard sodium thiosulfate solution using starch as indicator. This titration provided the means for estimating the constant for common product concentration. The microwave absorption data determine only a quantity proportional to the product concentration. The conversion in the substitution reaction is shown as a function of time. The order of the reaction with respect to the total amount of bromine is ca 0.75. 3 figures.
