摘要：
The effect of 18-crown-6 and kryptofix (2,2,1) on the oxidation of triethylamine by aqueous ferricyanide ion has been studied at pH 4, 7, and 9. The macrocycle retarded the normal oxidation process at all pH values, the effect depending on the macrocyclic ligand concentration Kryptofix (2,2,1) had a greater effect than 18-crown-6 at all pH values in this study. For 18-crown-6, retardation decreases in the order pH 9 > 4 > 7 while for kryptofix it follows the order pH 9 > 7 > 4.
