[0002] For nitrification, nitrosation reactions or other highly exothermic reactions, a large amount of heat will be released. In the case of untimely heat conduction, excessive temperature will lead to out-of-control reactions, not only posing a risk of side reactions, but even potentially causing an explosion.
