Abstract

N,N-dialkylamides, (octan-, decan- and dodecanamides) having ethyl and butyl groups as alkyl substituents, were synthesized in order to investigate their selectivity and capability in the extraction of Th(IV) from acidic nitrate media (3 and 6M HNO3) in nuclear reprocessing. The distribution ratios of Th (IV) with the amides in kerosene decrease with the increase of the alkyl chain length (C8, C10, C12), probably due to steric hindrance.
