Safe venting of ''red oil'' runaway reactions

摘要

Calorimetry testing of Tri-n-butyl phosphate (TBP) saturated with strong nitric acid was performed to determine the relationship between vent size and pressure buildup in the event of a runaway reaction. These experiments show that runaway can occur in an open system, but that even when runaway is induced in the TBP/HN0(sub 3) system, dangerous pressure buildup will be prevented with practical vent size.
