Endothermic Reaction

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
Endothermic Reaction 

a chemical reaction that is accompanied by the absorption of heat. Endothermic reactions include dissociation (in particular, the division of molecules into free atoms), photosynthesis in plants, the formation of certain compounds from simple substances, and the process of producing metals from ores by reduction reactions. Endothermic reactions are the reverse of exothermic reactions, during which heat is released.

The main underlying mechanisms are: * To slow down the spread of fire by diluting oxygen with non-combustible gases, which will also absorb some of the heat; * To lower combustion temperatures by endothermic reactions.
The resulting endothermic reaction cools the product below flash point, reducing the risk of fire.
By using conventional graphical methodologies to determine the kinetic parameters of the easily isolatable imidization reaction, the authors were able to deconvolute both endothermic reactions (amidation and imidization) and approximate with good accuracy the more complex amidation reaction kinetics.
