Description
Thermochemical interaction of TBP with nitric acid in single-phase organic systems has been studied at the concentrations of HNO3 1.4 to 5.6M, in temperature range of 110-140 deg C. The thermochemical oxidation of TBP includes a number of consecutive and concurrent reactions, such as acid hydrolysis, the oxidation of the TBP hydrolysis products, and TBP destructive oxidation. Some of these reactions can proceed with heat explosion. The limiting temperature (120-130 deg C) and acid concentration (2.5 mol/l) at which the oxidation reactions are able to transform to heat explosion have been estimated. The rate constants and activation energies were determined for the reactions presenting a potential hazard. (author)
