Method for improving the extraction properties of a tributyl phosphate solution
Patent
·
OSTI ID:7186507
A method is given for improving the extraction properties of a tributyl phosphate extractant used for reprocessing irradiated nuclear reactor fuel (Purex Process) containing degradation products of tributyl phosphate. The extractant is contacted with diazomethane in a suitable solvent, whereby the degradation products are esterified to triester phosphates which have extraction properties similar to those of tributyl phosphate.
