The kinetics of the reaction of iodide ion with methyl p -toluenesulfonate have been investigated at 25,30,35,40 and 45℃ in methanol,ethanol,n-propanol,acetone and dimethylformanide and in mixture of acetone and water. The pre-exponential factor,activation energy and activation entropy de-temined by using the Arrhenius and TST equations with the linear least-squares. The energy and entropy of activation decrease with increasing mol fraction of water in the mixture of acetone and water. From our experiments we...

The kinetics of the reaction of iodide ion with methyl p -toluenesulfonate have been investigated at 25,30,35,40 and 45℃ in methanol,ethanol,n-propanol,acetone and dimethylformanide and in mixture of acetone and water. The pre-exponential factor,activation energy and activation entropy de-temined by using the Arrhenius and TST equations with the linear least-squares. The energy and entropy of activation decrease with increasing mol fraction of water in the mixture of acetone and water. From our experiments we obtained that a solvent cage is made up of about 16-18 solvent molecules.

China is one of the worst countries with high prevalence of iodine deficiency, at the same time there are districts with excess iodine.In this experiment Dx resin is screened by comparing several sorts of adsorption materials and ion exchange resins. Dx resins can dislodge the iodide ion in experimental water quickly, its removal rate is 99.87% in 2-hour dynamic experiment. Its exchange volume is large,1.5g Dx resin can dispose of the same condition water 275 litres and the concentration of iodide ion in filtered water is below 300μg/L, more than 320 litres come to saturation.Dx resin has strong competitive adsorption K I\+-/F\+- =42.77,K I\+-/SO\-4\+\{2-\} =9.15,and its regenerative method is simple.So Dx resin is the to dislodge the iodide ion in the experimental water.
