Reaction hazard index

D. R. Stull11 developed a rating system to establish the relative potential hazards of specific chemicals the rating is called the reaction hazard index (RHI). The RHI is related to the maximum adiabatic temperature reached by the products of a decomposition reaction. It is defined as... [Pg.542]

A square with T increasing upward from 0 to 3000°K was plotted on the left side, while Ea was plotted on the right side with values from 0 to 100 kcal/mole increasing in the opposite direction (downward). The diagonal line connecting the zeros of the two scales was named the Reaction Hazard Index, or RHI for short. The end of the RHI line at 0°K would unquestionably be at minimum hazard (or zero index), while the end of the RHI line at 0 kcal/mole (zero activation energy) must surely... [Pg.19]
