This study offers a new simplified approach of diglycolamides synthesis, extraction agents used in separation procedures in various fields of nuclear chemistry such as waste management, spent nuclear fuel reprocessing, radioecology or radiopharmacy. The synthesis is assisted by coupling agent, propylphosphonic anhydride, commercially known as T3P (R). Using this agent allows to perform the synthesis in a single step and to synthesize also novel types of diglycolamides that have not been described, yet. Thus, this approach helps to widen the spectrum of prepared diglycolamides and possible use of these extraction agents. Prepared diglycolamides insoluble in water were immobilized on polymer matrix and used as solid extractants in pilot batch experiments with Eu(III) ions in order to confirm the quality of known diglycolamides and asses the quality of novel ones.
