The salient point about making isopropyl iodide, is that the farmer's "Stronger Iodine Solution", a standard article of commerce, is not composed of the same ingredients as the familiar 2% drugstore tincture, with its water, ethanol, iodine and sodium iodide.
Instead, the 7% iodine consists of 7% iodine in dry isopropanol. It's a ready-made reagent for this, just add aluminum glitter and heat. (If you do use aluminum flake, bee prepared with a cooling bath to moderate its initial intensity.) I haven't run this yet, but plan to do so with the following end in mind: to react i-propyl iodide with fused sodium acetate to produce the ester i-propyl acetate water free, less drying and purification labor to make use of such ester in anhydrous reactions.
A further incentive, is that I dislike the loss and mess of pulling elemental iodine out of the isopropanol, so I'm looking for a clean way to get a handle on that iodine in a less lossy way, eventually in its salt. I expect there may bee some elimination to propylene, but this shouldn't prove a major factor.
