Ethylene iodohydrin

Chlorine and bromine can be replaced by iodine by means of alkali iodide, and this is of importance in cases where direct treatment of alcohols with hydriodic acid gives a bad yield or none at all, e.g. in the preparation of ethylene iodohydrin ...

The most popular cleanup method now is headspace GC or headspace GC-MS, which permits automated analysis of dozens of samples and standards in a single campaign. Vacuum distillation is at least as sensitive and accurate as headspace GC, but only a few samples and standards can be analyzed in a day. A number of liquid-liquid and liquid-solid extraction methods have been proposed to isolate 1,4-dioxane from surfactants prior to GC determination, but recovery varies with each matrix (55). The purge-and-trap methods used in environmental analysis are rarely applied to analysis of surfactants, since the impurities of interest are not readily adsorbed from the purge gas stream. In order to gain the high sensitivity of electron capture detection, ethylene oxide may be stripped and converted to ethylene iodohydrin before GC analysis (59). Detection limits in the low parts per billion range are claimed for this technique. 

Aiyl-substituted ethylene oxides have also been prepared. The simplest of these is styrene oxide, which is prepared by the alkali treatment of the iodohydrin made by the action of iodine, water, and mercuric oxide on styrene (51%). Aryl chlorohydrins resulting from the action of chloro-acetone and aromatic Grignard reagents, C,Hj (CHj)nMgX, have been converted by alkali or sodium ethoxide to oxides of the type...
