Octadecyl alcohol

Hexadecyl and octadecyl alcohol have been extensively studied and shown to be highly effective in evaporation retardation. Scattering powdered samples of commercial-grade alcohols by boat on lake surfaces or the continuous addition of alcohol slurries from floating dispensers are two of the methods that have been employed to apply these monolayers. Wind conditions and the activity of aquatic birds have a considerable effect on the stability of the monolayer and therefore on the rate at which the monolayer chemicals must be reapplied. Rates of application rarely exceed 0.5 lb acre- day-1, however, so that the cost of the materials used is not excessive.

A mixture of 7.8 g. (0.062 gram atom) of iodine and 1 g. of red phosphorus is put in a flask equipped with an air condenser on which is placed a calcium chloride tube to protect the system from atmospheric moisture. The flask is heated in an oil or metal bath to a temperature of 100°, and 15.6 g. (0.058 mole) of n-octadecyl alcohol is added. The bath temperature is then raised to 180° and held there for 1 hour. The cooled reaction mixture is extracted with petroleum ether (b.p. 70-80°), and the resulting solution is boiled with fuller s earth and filtered. The solvent is evaporated from the filtrate, giving 21.5 g. (97.5%) of n-octadecyl iodide melting at 34.5-35°.
