Reaction Kinetics: Fundamentals and Applications

Reaction kinetics is the study of the rates at which chemical reactions proceed. The method investigates the effect of temperature and yields information about reaction mechanisms. Join this webinar to learn why kinetics is very important for process development and safety investigations as well as for understanding the curing behavior of thermosets.

Overview

In this webinar, we will explain the fundamentals of reaction kinetics and describe some interesting application examples.

Reaction kinetics dates back to the 19th century (Wilhelmy 1850 and Arrhenius 1889) and has since developed into a very useful method for chemists and physicists. It allows a reaction to be described in mathematical terms. Even more important is the possibility of predicting the behavior of a sample outside the practical measurement range.

Reaction kinetics yields information on aging, oxidation stability, product lifetime, shelf life and process optimization without the need for time-consuming measurements. Model-free kinetics is a new approach that makes no assumptions about the reaction model. As a result, you cannot choose the wrong model and the results become more reliable.

The advantages of model-free kinetics are:

  • Kinetic evaluations can be made without having to choose a reaction model
  • The method can be applied to both simple and complex reactions
  • Simulation studies are possible, e.g. prediction of the reaction kinetics under other conditions

Key Takeaways

  • Discover information for the design of chemical processes, including the influence of temperature, time, concentration, catalysts and inhibitors
  • Understand reaction rate (mathematical description) to learn how fast a reaction proceeds
  • Understand simulation studies for less trial-and-error in scale-up, safety and stability data

Dr. Angela Hammer, Thermal Analysis Senior Applications Chemist, Mettler-Toledo, Analytical

Dr. Angela Hammer studied chemistry. During her dissertation at the Institute of Organic Chemistry at the Swiss Federal Institute of Technology in Z├╝rich, Switzerland, she specialized in the development of immobilized components in ion-selective electrodes based on polyurethane membranes.

She then joined Sika Technology AG in Zurich Switzerland, as an Analytical Chemist. In 2007 she joined Mettler-Toledo AG and has worked there since as application specialist for Thermal Analysis. In her present position she uses, teaches and supports DSC, TGA, TMA and DMA instruments at the Mettler-Toledo AG head office in Switzerland.
