Applications Related to Polymerization Reactions

Control Residual Isocyanate
Process Analytical Technology for Continuous Measurement of NCO

Isocyanates are critical building blocks for high performance polyurethane-based polymers that make up coatings, foams, adhesives, elastomers, and insulation. Concerns over exposure to residual isocyanates led to new limits for residual isocyanates in new products. Traditional analytical methods for measuring the residual isocyanate (NCO) concentration using offline sampling and analysis raise concerns. In situ monitoring with process analytical technology addresses these challenges and enables manufacturers and formulators to ensure that product quality specifications, personnel safety, and environmental regulations are met.

Chemical Reaction Kinetics Studies
Study Chemical Reaction Rates and Measure Kinetics Inline

In situ chemical reaction kinetics studies provide an improved understanding of reaction mechanism and pathway by providing concentration dependences of reacting components in real-time. Continuous data over the course of a reaction allows for the calculation of rate laws with fewer experiments due to the comprehensive nature of the data.  Reaction Progression Kinetics Analysis (RPKA) uses in situ data under synthetically relevant concentrations and captures information throughout the whole experiment ensuring that the complete reaction behavior can be accurately described.

Heat Transfer and Process Scale-up
How Heat Transport in Agitated Vessels Affects Process Scale-up

Scaling-up a chemical process from lab to manufacturing gives useful results only with accurate heat transfer coefficients. Measuring the jacket and reactor temperature (during the release of a well-defined amount of heat) allows researchers to accurately compute the thermal resistance which is used to model the heat transfer and make critical predictions for reactors at larger scale. Reaction calorimetry is essential to determine parameters that impact the heat transfer and the heat transfer coefficients to develop models to maximize the bandwidth of a manufacturing plant. 

Mass Transfer and Reaction Rate
Mixing in a Chemical Reactor and the Effect on Reaction Kinetics and Scale-up

Mixing is the reduction or elimination of inhomogeneity of phases that are either miscible or immiscible. Process scale-up and optimization require that the impact of mixing on the reaction rate be quantified. Automated, controlled experiments can be run in parallel in a laboratory reactor system to establish a mass transfer correlation, and provide a means to quickly adjust the gas/ liquid interface area and reactor volume. This achieves the desired conditions required for the scale-up or scale-down of a process.

Continuous Flow Chemistry
Improve Safety, Reduce Cycle Time, Increase Quality and Yield

Continuous flow chemistry opens options with exothermic synthetic steps that are not possible in batch reactors, and new developments in flow reactor design provide alternatives for reactions that are mixing limited in batch reactors. This can often result in better product quality and higher yield.  When coupled with Process Analytical Technology (PAT), flow chemistry allows for rapid analysis, optimization, and scale-up of a chemical reaction.

Chemical Process Safety
Determine the Safety of Chemical Processes Prior to Scale-up

How can I be sure that my chemical process is safe? It is critical to understand the risks inherent in moving a chemical process to a larger scale before manufacturing begins. The use of reaction calorimetry is an essential part of process development studies, providing detailed information about the rate of heat production. This allows researchers to optimize the temperature and dosing profiles to maximize process safety at all times, and reduce to a minimum the risks involved.

Process Analytical Technology (PAT)
PAT is Changing Chemical Process Development, Scale-up, and Manufacturing

Process Analytical Technology (PAT) is changing the way R&D, scale-up, and manufacturing are performed. PAT transforms productivity, improves safety, and provides measurements for rapid troubleshooting. Process Analytical Technology (PAT) applications range from monitoring chemical reactions, crystallization, formulations, and bioprocessing.
