Decomposition of Hydroxylamine/Water Solution added Iron Ion
Abstract
The decomposition hazards of hydroxylamine (HA)/water solution with and without the addition of the iron ion were studied in this paper. Tests were conducted to obtain information about the decomposition hazards of HA/water solution following the United Nations recommendations on transport of dangerous goods. The decomposition hazards were discussed on the basis of thermal stability and the intensity of the thermal decomposition. When the heat accumulation storage test was conducted using HA50wt.%/water solution without the addition of the iron ion, the self-accelerating decomposition temperature (SADT) was 80 °C. Therefore HA50wt.%/water solution was not classified in self-reactive substances following the United Nations recommendations on transport of dangerous goods. The 0 concentration of the iron ion in HA50wt. ~/water solution was not more than l ppm. The decomposition hazards of HA50wt.%/water solution with a very small amount of the iron ion were investigated. The range of the concentration of the iron ion in HA/water solution 0 used in tests was between l ppm and 6ppm. The thermal stability of HA50wt. ~/water solution decreased by the addition of the iron ion in the heat accumulation storage test. HA50wt.%/water solution with the addition of the iron ion was classified in self-reactive substances following the United Nations recommendations on transport of dangerous goods. The Koenen test was conducted using HA50wt.%/water solution with the addition of the iron ion. The intensity of the thermal decomposition of HA50wt.%/water solution increased by the addition of the iron ion.
