Properties and stability
Keep away from light, oxides.
Storage method
Store in an airtight container, protected from light and refrigerated. The storage area must be locked and the keys must be kept by the technical experts and their assistants. Keep away from oxides, light.
Synthesis method
Derived from the reaction of chloroethanol and sodium iodide. Heat the mixture of acetone and anhydrous sodium iodide on a water bath to reflux, and slowly add chlorohydrin. After the addition is completed, continue to reflux for 12 hours, cool, and filter out the sodium chloride crystals. Then add sodium iodide to the filtrate and continue to reflux for 4 hours, cool, filter, and recover acetone. Distill the residue under reduced pressure under nitrogen protection and collect the 85-88°C (3.33kPa) fraction to obtain 2-iodoethanol.
Purpose
Used in organic synthesis.
