8-Ethyl-2,2,4-trimethyl-6-dodecanol (b.p. 86°-90° at 0.15 mm of mercury pressure) was prepared by reacting 1-bromo-2-ethylhexane and 3,5,5-trimethylhexanol with lithium in tetrahydrofuran at 0° to -10° according to the general method of Pearce, Richards and Scilly (J.Chem. Soc., Perkin I, 1655, 1972). This compound was converted, by way of the chloroformate, into 1-[8-ethyl-2,2,4-trimethyl-6-dodecyloxycarbonyl]-1,2,4-triazole of formula: ##STR18## The compound was evaluated as an extractant for copper by the procedure of Example 1 and the results are presented in Table 2.
