Separation of the Tributyl Phosphate-Kerosene Extraction Mixture Using Formic Acid

Separation of the TBP-kerosene extraction mixture using formic acid was studied, and the optimal process parameters were determined. The experimental data strongly suggest formation of the solvate (C4H9O)3PO·3HCOOH. The thorium distribution in separation of the TBP-kerosene mixture into two phases was studied.
