Recognizing and Controlling Exothermic Chemical Reactions

Recognizing and controlling exothermic chemical reactions

Chemical reactions - a special form of energy release.

During the synthesis of chemical products, the reaction that takes place as intended often releases energy in the form of heat - the process is exothermic. However, heat of reaction can also be released unintentionally when chemicals decompose under thermal stress (e.g. decomposition reactions during distillation or drying) or

2. react with each other in an unplanned manner (e.g. by mixing up chemicals when filling a container or as a result of polymerization reactions during the storage of monomers).

If the released heat is not dissipated in a controlled manner, a continuous reaction can occur.

Recognizing and controlling exothermic chemical reactions". This type of explosion does not require atmospheric oxygen because it is not a typical combustion reaction. For this reason, heat explosions - in contrast to explosions in the gas/vapor or dust phase - do not fall within the scope of the Technical Rules for Hazardous Substances TRGS 720 ff, and the measures to prevent heat explosions cannot be covered by the explosion protection document in accordance with Section 6 (9) of the Hazardous Substances Ordinance.
