II. On the action of chloride of iodine upon organic bodies

Abstract

In a former communication I stated to the Society that chloride of iodine combines directly with ethylene and propylene gases. I have since ascertained that it also directly combines with those radicals which are at the same time both mono- and tri-atomic. Iodide of allyle and bromide of aldehydene, having the desired atomicity, were the bodies I selected for my experiments. Action of Chloride of Iodine on Iodide of Allyle .—In order to determine the union of these bodies, it was simply necessary to mix and agitate them. The chloride of iodine used was in the form of a watery solution. During the agitation the mixture became warm, and assumed a dark colour from the liberation of iodine. To complete the reaction, it was gently heated over the lamp for a short time. By these means a dark oily liquid was obtained, which was separated from the excess of chloride of iodine, washed with dilute potash, then with pure water, and distilled. Almost the entire liquid passed over between 190° and 215° Cent, The fraction distilling between 205 and 210 being very considerable in quantity, was collected separately and analyzed, having been previously decolorized by agitation with mercury. The numbers obtained correspond sufficiently well with the formula C 6 H 5 Cl 2 I, as will be seen from 'the following Table.
