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.

Misura delle reazioni polimeriche
Tecniche e metodi per lo sviluppo dei polimeri sintetici

La misura nelle reazioni polimeriche è fondamentale per produrre materiali conformi ai requisiti, assicurando immediata comprensione, accuratezza, riproducibilità e maggiore sicurezza.

Impurity Profiling of Chemical Reactions
Automated Process Development Strategies for Chemists

Impurity profiling aims at identification and subsequent quantification of specific components present at low levels, usually less than 1% and ideally lower than 0.1 %.

Chemical Reaction Kinetics Studies
Fundamental Understanding of Reactions Rates and Factors Affecting Them

Chemical reaction kinetics, also known as reaction kinetics, reflect rates of chemical reactions and provide a better understanding of their dependencies on reaction variables. Reaction kinetic studies provide enhanced insight into reaction mechanisms. Learn how to obtain data rich information for more complete reaction kinetic information.

Chimica a flusso continuo
Ridurre la durata del ciclo e migliorare la sicurezza, la qualità e il rendimento

La chimica a flusso consente di realizzare fasi esotermiche di sintesi altrimenti impossibili con i reattori discontinui. Inoltre, i miglioramenti nella progettazione dei reattori continui moltiplicano le possibilità di reazione, cosa che risulta limitata nei reattori discontinui. Ciò si traduce spesso in una migliore qualità del prodotto e in un rendimento più elevato.  Associata alla Process Analytical Technology (PAT), la chimica a flusso consente di eseguire rapidamente analisi, ottimizzazione e scale-up delle reazioni chimiche.

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.

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
Understanding Key Mechanisms and Improve Catalytic Processes

Hydroformylation, or oxo synthesis, catalytic processes that synthesize aldehydes from alkenes. The resultant aldehydes form the feedstock for many other useful organic compounds.

Halogenation Reactions
Key Syntheses in Pharmaceutical and Polymer Chemistry

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..

reazioni di sintesi
Per fornire molecole importanti ai settori di ricerca, industria e commercio

Una delle quattro categorie principali di reazioni chimiche, quella delle reazioni di sintesi, è rappresentata da importanti esempi tra le reazioni di sintesi organica, le reazioni chimiche catalizzate, le polimerizzazioni e le reazioni di chimica inorganica/organometallica. Nel caso più semplice, una reazione di sintesi ha luogo quando due molecole si combinano tra loro per formare un prodotto costituito da una molecola più complessa. Spesso, le reazioni di sintesi sono più complesse di così e richiedono una comprensione approfondita della cinetica e dei meccanismi chimici sottostanti, oltre a condizioni di reazione controllate con attenzione.

Progettazione degli esperimenti (DoE)
Un approccio statistico all'ottimizzazione delle reazioni

La progettazione degli esperimenti (DoE) prevede l'esecuzione di esperimenti in condizioni ben controllate e riproducibili per l'ottimizzazione delle reazioni chimiche. I reattori di sintesi chimica sono progettati per effettuare studi di DoE garantendo dati di qualità elevata.
