Synthetic Organic Chemistry Applications

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.

Measuring Polymerization Reactions
Comprehensive Understanding of Kinetics to Develop Synthetic Polymer Chemistry

Measuring and understanding polymerization reactions, mechanisms, kinetics, reactivity ratios, and activation energies lead researchers to employ in situ infrared spectroscopy as a routine technique to gain comprehensive, information-rich data that is used to advance research in a shorter time frame.

Impurity Profiling of Chemical Reactions
Continuous Automated Reaction Sampling Improves Productivity and Understanding for Chemists

Knowledge of impurity kinetics and mechanism of formation is important in determining reaction end-point in chemical and process development studies. Accurate, reproducible, and representative reactions samples are necessary for these studies.

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.

Grignard Reaction Mechanisms
Understand and Control Exothermic Events

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 widely used in the manufacture 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 such as in situ FTIR, calorimetry and automated, in situ sampling 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.

Hydroformylation or Oxo Synthesis/Process
Understand Catalyst Activity

Hydroformylation, or oxo synthesis/process, is important for the production of olefins to aldehydes and aldehydes from alkenes. Hydroformylation reactions are performed at high pressure and can be challenging to sample due to the extreme reaction conditions, as well as the toxic, flammable, and reactive raw materials and reagents.

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..

synthesis reactions
Providing Important Molecules for Research, Industry, and Commerce

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.

Design of Experiments (DoE)
A Statistical Approach to Reaction Optimization

Design of Experiments (DoE) requires experiments to be conducted under well-controlled and reproducible conditions in chemical process optimization. Chemical synthesis reactors are designed to perform DoE investigations ensuring high quality data.

Fundamental Understanding of Chemical Reactions and Factors Affecting Them

Reaction mechanisms describe the successive steps at the molecular level that take place in a chemical reaction. Reaction mechanisms cannot be proven, but rather postulated based on empirical experimentation and deduction. In situ FTIR spectroscopy provides information to support reaction mechanisms hypotheses.
