Notes:
Surface active N-oxyl radicals containing aliphatic chains were prepared from palmitinic, stearic and oleic acid chlorides by reaction with 4-hydroxy-(or-4-amino-) 2,2,6,6-tetramethyl-piperidine or its N-oxyl. In the former case the resulting esters or amides were subsequently oxidized. A dioleyl ester (3b) was prepared analogously from 2,2,6,6-tetramethyl-4-bis(2-hydroxyethyl)aminopiperidine. Surface tension data of aqueous solutions were determined and micelle formation was confirmed by light transmission measurements. The size of the water droplets in hexane solution of the dioleoyl derivative was estimated by the fluorescence spectroscopic method to 4,62 nm.
