Monitoring the pH-Dependent Oximation of Methyl Ethyl Ketone and Benzaldehyde by in situ Fourier Transform IR Spectroscopy in a Heterogeneous Liquid–Liquid Two-Phase System

Monitoring the Phosphorylation of Phenol Derivatives with Diethyl Chlorophosphate in Liquid–Liquid and Solid–Liquid Phase by In Situ Fourier Transform Infrared Spectroscopy, Part II

“…1 Hence, in situ FT IR spectroscopy may be an important tool in environmentally friendly ("green") chemistry. In addition, intermediates can be observed, 6,7 and equilibrium constants 8 can be determined by utilizing this up-to-date technique that is spreading in the chemical industry. Organophosphorus reactions may also be monitored by the in situ FT IR method.…”

A study on the Kabachnik–Fields reaction of benzaldehyde, propylamine, and diethyl phosphite by in situ Fourier transform IR spectroscopy

“…In situ Fourier transform infra‐red (FT‐IR) spectroscopy is a useful tool in environment friendly chemistry, as it allows optimization of the reaction conditions via monitoring the concentration profile of the components 1–5. The time‐dependent IR spectra also allow the establishment of formal kinetics or equilibrium constants 6,7 as well as detection of intermediates 8,9. In situ FT‐IR spectroscopy has been applied only rarely in organophosphorus chemistry 5,10,11.…”

A study on the equilibrium reaction of benzaldehyde and sodium bisulphite by in situ Fourier transform IR spectroscopy

“…This latter is important from the point of view of environmentally friendly chemistry. It is also possible to identify intermediates [7,8] in the mixture and hence evaluate reaction mechanisms. In situ Fourier transform IR spectroscopy is a suitable tool to study organic chemical reactions over a wide range of temperatures, and even under pressure.…”

“…In situ Fourier transform IR has become a routine method in the fine chemical, pharmaceutical, and even plastics industries. Heterogeneous phase reactions can also be monitored by in situ Fourier transform IR spectroscopy [8].…”

“…In situ Fourier transform IR spectroscopy is a suitable method for monitoring a variety of organic chemical reactions [1]- [8]. The time-dependent IR spectra reveal the concentration profile of the components, which allows formal kinetic measurements, determination of equilibrium constants [2], and optimization of the reaction studied.…”
