摘要:

The oxidative destruction of unsymmetrical dimethylhydrazine (UDMH) by a molar excess of Ca(OCl)2leads mainly to formaldehyde dimethylhydrazone and tetramethyl tetrazene, but not to N-nitrosodi-methylamine (NDMA). An alternate method using H2O2/CuSO4leads to ca. 25% NDMA. The amount of UDMH destroyed is affected by the order of addition of the H2O2, and CuSO4: when the CuSO4is added first, only ca. 65% of the UDMH is destroyed, while the reverse order of addition leads to 100% destruction of UDMH.
