ABSTRACT
As a general rule of thumb, a reaction that generates a heat of reaction of 1 kcal/gram or greater is significantly exothermic, while a value exceeding 2 kcal/gram is a very hot reaction. When a composition with a heat of reaction well below 1 kcal/gram is encountered, concerns should begin to rise regarding the ability of the reaction to propagate under adverse conditions, such as low ambient temperatures or the use of a small-diameter column of minimally confined energetic material.
