Abstract
The kinetics of thermochemical reaction of 30% TBP in hexachlorobutadiene (HCBD) saturated with HNO3 (1.35 M HNO3) in two-phase systems with 12 M HNO3 at temperatures from 90 to 115°C was studied. The kinetic parameters of thermolysis of organic solutions of TBP in HCBD, contacting with HNO3 in open and closed vessels, were determined experimentally for the subsequent estimation of the explosion hazard of these systems under conditions of extraction recovery of high-level radioactive materials. It was shown that, in two-phase systems, solutions of TBP in HCBD exhibit increased resistance to thermochemical oxidation with nitric acid in comparison with hydrocarbon solutions of the extractant in the entire temperature range.
