摘要

1. Diamides of 4,7-disubstituted 1,10-phenanthroline-2,9-dicarboxylic acids of the formula R are radicals selected from the group consisting of alkyl (ethyl) or aromatic (phenyl) groups, X is a radical selected from alkoxy groups (n-pentoxy), halogen atoms (chlorine) or aromatic (phenyl) groups. 2. A method of producing diamides of 4,7-disubstituted 1,10-phenanthroline-2,9-dicarboxylic acids, characterized in that disubstituted 1,10-phenanthroline-2,9-dicarboxylic acids are treated with thionyl chloride and the corresponding amines to obtain the desired products.3 . The 4,7-disubstituted 1,10-phenanthroline-2,9-dicarboxylic acid of the formula X is a radical selected from the group consisting of alkoxy (n-pentoxy) or aromatic (phenyl) group. 4. A method of producing 1,10-phenanthroline-2,9-dicarboxylic acids, characterized in that the 4,7-disubstituted 2,9-dimethyl-9,10-phenanthroline is oxidized with selenium dioxide in wet dioxane or by chlorination with N-chlorosuccinimide in the presence of benzoyl peroxide .5. An extraction mixture for the separation of actinides from liquid radioactive waste containing an extractant in meta-nitrobenzotrifluoride, characterized in that diamides of 4,7-disubstituted 1,10-phenanthroline-2,9-dicarboxylic acids in an amount of 0.05- are used as a neutral extractant 0.15 mol / L. 6.
