In chemical process scale-up, understanding temperature change and the associated heat that is accumulated by the reaction are critical to process safety.
Process Development of Organosilicon Flame Retardants
Mike DiPierro, John Gohndone, and Brian Deeth discuss the process development of organosilicon flame retardants at Dow Performance Silicones.
This webinar includes practical examples and case studies from Dow Performance Silicones. Join the over 500 researchers who have already viewed this presentation.
Dow Performance Silicones developed a process for a new silicon-based, halogen-free flame retardant. The production process of organosilicon flame retardants requires careful control of an exothermic reaction. In situ FTIR spectroscopy and reaction calorimetry were used for the process development. In situ FTIR spectroscopy helped to understand how different parameters affect the reaction rate and chemical structure. The real-time monitoring capability helped avoid accumulation of energetic reactants and mitigated the risk of a run-away reaction. Reaction Calorimetry was used to gather additional information about the reaction, including:
- Heat of Reaction
- Temperature Effects
- Initiation Behavior
Using advanced process analytical tools, a large amount of information was gathered with just a few carefully planned experiments, and a safe, scalable process was developed.
