In 2013, we added a KIN experiment in combina-tion with the FLO, VLE, and HEX experiments. In the KIN lab, the un-dergraduate students run either the iodination or bromination of acetone reaction. …
WebThe iodine solution is added dropwise at such a rate that the entire quantity of iodine is added over a period of 45-74 minutes. If the iodine is added too rapidly, iodination of acetone will take place. Caution. Iodoacetone species are extremely powerful lacrimators. Web21 dec. 1970 · acetone at 30'. axis without any evidence of tailing. The shape of the graph is a qualitative test for kinetic dependence on bromine concentration. Acetone is not a good system for quantitative com- parison of theory with experiment because of SN2 reaction of bromoacetone and because of bromination of 1,1,1-tribromoacetone.
Web18 aug. 2016 · Specific ion effects on the kinetics of iodination of acetone in an acidic medium are investigated by UV/Vis spectrophotometry as a function of nature of the acid and temperature.
