1,5,9-TRIAZACYCLODODECANE DERIVATIVES, METHOD FOR THE SOLVENT EXTRACTION OF GOLD FROM ALKALINE CYANIDE SOLUTION BY USING THE DERIVATIVES

摘要

The present invention than the process for producing a-aza crown compound to provide an improved yield, 1,5,9- triaza-bicyclo also a lipophilic obtained by selective alkylation with a strong base decane New Castle 1,5,9- triaza-bicyclo FIG decane derivatives and their preparation, and these 1,5,9- triaza-bicyclo also relates to a solvent extraction method of using a gold-decane derivatives.
