Microwave chemistry - Wikipedia

Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid.Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions.

Energy, Enthalpy, and the First Law of Thermodynamics

Thus, the heat given off or absorbed during a chemical reaction at constant pressure is equal to the change in the enthalpy of the system. H = q p (at constant pressure) The relationship between the change in the internal energy of the system during a chemical reaction and the enthalpy of reaction can be summarized as follows. 1.

Jacketed vessel - Wikipedia

Heat Transfer In Jacketed Vessels

Jacketed vessels can also be employed as chemical reactors - to remove the elevated heat of reaction - or to reduce the viscosity of highly viscous fluids such as tar. Agitation can be also used in jacketed vessels to improve the homogeneity of the fluid's properties (such as temperature or concentration).

Thermal Explosion - an overview | ScienceDirect Topics

Thermal runaway reactions are the results of chemical reactions in batch or semi-batch reactors. A thermal runaway commences when the heat generated by a chemical reaction exceeds the heat which can be removed to the surroundings as shown in Figure 9-81.The surplus heat increases the temperature of the reaction mass, which causes the reaction rate to increase, and subsequently accelerates the .
