18,19 Consequently, some of these volatile amines induce attraction, while others lead to aversive reactions. It is still a matter of debate, whether the primary ligands for the founding members of this family were indeed TAs or volatile amines. Thus, it is still not clear whether the ...
Amines closely resemble the ammonia molecule, NH3. Amines can be primary, secondary or tertiary depending on how many hydrogen atoms are replaced by R groups. Amines are responsible for many pungent smells including rotting fish. Amines take part in many acid:base reactions and are very important...
FINTEPLA can cause an increase in blood pressure [seeADVERSE REACTIONS]. Rare cases of significant elevation in blood pressure, including hypertensive crisis, has been reported in adult patients treated with fenfluramine, including patients without a history of hypertension. In clinical trials of up ...
However, compared to the rate ofreaction 7.1for MEA, the other two reactions make a minimal contribution to the overall CO2absorption rate. For asecondary amine, the equivalent carbamation reaction would be as follows: (7.4)2R1R2-NH+CO2→R1R2-NH2++R1R2-NCOO−+heat ...
Herein, we design and prepare cellulose-based ratiometric fluorescent materials with superior amine-response, which offers the real-time and visual detection of seafood freshness. Through utilizing the reactive hydroxyl groups along cellulose chains, we
Various methods, many with an eye towards industrial application, have been examined to accelerate Cannizzaro reactions. For example copper-silica catalysts,25 Na2S, Na2S2O3 or Na2SO3 supported on Al2O3, and ultrasound all have been reported to accelerate certain Cannizzaro processes.26 An ext...

In practice, initiation occurs by exposing the photoinitiator to actinic radiation, which in turn, causes the release of one or more cations from the photoinitiator. The term "actinic radiation" is defined to mean any type of radiation which enables the liberation of cations from the ...
However, problems associated with the device corrosion, as well as an excessive increase in viscosity by increase in MEA concentration must be considered as the limiting factors [57–59]. In Fig. 8c, it is recognized that the KGaV value has increased to the peak with the increase in gas ...
The carbinols useful in the reactions of the present invention must have a conjugate structure with an acidic character. These two characteristics are required for the carbocation formation in the presence of the cationic effect reagent. Hydroxy-aryl carbinols ...
