1-Chlorooctadecane Usage And Synthesis

Chemical Properties

clear colorless to yellowish liquid after melting

Uses

1-Chlorooctadecane has been used as internal standard for the determination of endocrine disrupters in water samples by stir bar sorptive extraction method.

General Description

Kinetic and thermodynamic analysis of catalytic hydrodechlorination of 1-chlorooctadecane in supercritical carbon dioxide using 5% Pd supported on γ-Al₂O₃ has been reported. Incorporation of 1-chlorooctadecane into a host monolayer of stearic acid has been reported.

Synthesis

The general procedure for the synthesis of chlorinated octadecanes from octadecanol is as follows: for the preparation of n-octadecyl chloride compounds in a semicontinuous process, 220 g of Nn-octadecyl alkyl pyridinium chloride (prepared according to Example 2) is first added to a 1 liter jacketed glass reactor equipped with a glass paddle stirrer and a reactant metering immersion tube, and the temperature is adjusted to 150 °C. Subsequently, 447 g of n-octadecanol was uniformly added through the immersion tube over a period of 5 hours. Throughout the reaction, gaseous hydrogen chloride was added continuously in a slightly stoichiometric excess via the immersion tube and the resulting reaction water was removed synchronously by distillation. The reaction was carried out and the post-treatment steps of the reaction mixture were similar to Example 4a. The total duration of the reaction was 8 hours (including the reaction time after 3 hours), based on a 99.8% conversion of n-octadecanol.
