Study on the Thermodecomposition Kinetics and Runaway Reaction Simulation of N, N-Dimethylhydroxylamine in Nitric Acid Media

摘要

正As a new type of salt-free reductant, N, N-dimethylhydroxylamine (DMHAN) has a lot of advantages such as reducing Pu(Ⅳ) fast, reducing Np(Ⅴ) to Np(Ⅳ) slow and so on. DMHAN has been applied in 1B, 2B and 2D of APOR (advance process based on organic reductants), and have achieved a better separation of uranium and plutonium. DMHAN is a kind of hydroxylamine (HAN) derivant, and its
