1-Iodoheptane Chemical Properties,Usage,Production

Chemical Properties

It is a clear, colorless to pale yellow-orange liquid. It is not soluble in water but dissolves readily in ethanol, ether, acetone, and chloroform. If exposed to light or stored for a long time, it may become discolored.

Uses

1-Iodoheptane is used in the functionalization of symmetrical star-shaped molecules with carborane clusters.

Synthesis

The Synthesis of 1-iodoheptane is as follows:
Firstly, catechol reacts with phosphorus trichloride to produce o-phenylene phosphorous acid chloride, and then the produced compound reacts with heptanol to obtain colorless oily phosphite. Second, take 50.9g (0.20mol) of the above phosphite and 50.8g (0.20mol) of iodine into 500ml of dichloromethane. After that, stir at room temperature for 1h. Finally, use 10% sodium thiosulfate solution to wash away the unreacted iodine that may exist, then wash with 5% NaOH solution, 5% NaHCO3 solution, and saturated NaCl solution in turn, separate the organic phase, evaporate the solvent, and depressurize Distill and collect fractions at 96-104°C (5.33-6.4kPa) to obtain 39g 1-Iodoheptane with a yield of 86%.
