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.

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.

Grignard Reaction Mechanisms

Grignard reactions are one of the most important reaction classes in organic chemistry. Grignard reactions are useful for forming carbon-carbon bonds. Grignard reactions form alcohols from ketones and aldehydes, as well as react with other chemicals to form a myriad of useful compounds. Grignard reactions are performed using a Grignard reagent, which is typically a alkyl-, aryl- or vinyl- organomagnesium halide compound. To ensure optimization and safety of Grignard reactions in research, development and production, in situ monitoring and understanding reaction heat flow is important.

Hydrogenation Reactions
Safe Reaction Monitoring at Elevated Temperature and Pressure

Hydrogenation reactions are used in the manufacturing of both bulk and fine chemicals for reducing multiple bonds to single bonds. Catalysts are typically used to promote these reactions and reaction temperature, pressure, substrate loading, catalyst loading, and agitation rate all effect hydrogen gas uptake and overall reaction performance. Thorough understanding of this energetic reaction is important and PAT technology in support of HPLC analysis ensure safe, optimized and well-characterized chemistry.

Highly Reactive Chemistries
Scale-Up and Optimize Highly Reactive Chemistries

Highly reactive chemistry is a terminology used to describe chemical reactions that are particularly challenging to handle and develop due to the potentially hazardous and/or energetic nature of the reactants, intermediates and products that are present during synthesis. These chemistries often involve highly exothermic reactions which require specialized equipment or extreme operating conditions (such as low temperature) to ensure adequate control. Ensuring safe operating conditions, minimizing human exposure, and gaining the maximum amount of information from each experiment are key factors in successfully designing and scaling-up highly reactive chemistries.

High Pressure Reactions
Understand and Characterize High Pressure Reactions Under Challenging Sampling Conditions

Many processes require reactions to be run under high pressure. Working under pressure is challenging and collecting samples for offline analysis is difficult and time consuming. A change in pressure could affect reaction rate, conversion and mechanism as well as other process parameters plus sensitivity to oxygen, water, and associated safety issues are common problems.

Halogenation occurs when one of more fluorine, chlorine, bromine, or iodine atoms replace one or more hydrogen atoms in an organic compound. Depending on the specific halogen, the nature of the substrate molecule and overall reaction conditions, halogenation reactions can be very energetic and follow different pathways. For this reason, understanding these reactions from a kinetics and thermodynamic perspective is critical to ensuring yield, quality and safety of the process.

Catalytic Reactions
Accelerate Chemical Reactions With a Catalyst

Catalysts create an alternative path to increase the speed and outcome of a reaction, so a thorough understanding of the reaction kinetics is important. Not only does that provide information about the rate of the reaction, but also provides insight into the mechanism of the reaction. There are two types of catalytic reactions: heterogeneous and homogeneous. Heterogeneous is when the catalyst and reactant exist in two different phases. Homogeneous is when the catalyst and the reactant are in the same phase..

One of the four major classes of chemical reactions, synthesis reactions are represented by important examples in organic synthesis, catalyzed chemistry, polymerizations and inorganic/organometallic chemistry. In the simplest case, a synthesis reaction occurs when two molecules combine to form a third, more complex product molecule. Often, synthesis reactions are more complex and require a thorough understanding of the kinetics and mechanisms of the underlying chemistry, as well as carefully controlled reaction conditions.
