The Henry’s law constant defines the solubility of a gas in a liquid solution In this study, a new method for measuring the Henry’s law constant is described. This new colorimetric method is suited for gases which react with water to form acidic or basic solutions when they dissolve, and makes use of measuring the concentration of two forms of a colorimetric pH indicator. By measuring the concentration of the protonated and deprotonated forms of the indicator with UV-visible absorption spectroscopy, the concentration of the hydronium in solution was determined After determining the hydronium concentration, the equilibrium expression for the dissolved gas reacting with water was solved to determine the concentration of the dissolved gas. The concentration of the dissolved gas and the measured partial pressure of the dissolved gas at equilibrium were then used to calculate the Henry’s law constant for the gas. The efficacy of the method is demonstrated by measuring the Henry’s law constant for carbon dioxide in water over a range of pressures (0.680 – 5.10 atm). The results obtained with this method are comparable to the value for the Henry’s law constant that have been previously reported via more traditional methods, and yielded values for the Henry’s law constant for carbon dioxide that ranged from 3.45 x 10-2 to 3.99 x 10-2 M atm-1.

Author is Williamson, J. Charles.

The lever rule applies to any two-component system existing in a state of two-phase equilibrium Here, several classroom demonstrations are described to help students understand liquid-liquid coexistence and the lever rule using a set of isobutyric acid + water + dye samples ranging in composition from water + dye to isobutyric acid + dye. The critical temperature of the partially miscible isobutyric acid + water system is just above room temperature, so students can perceive the general shape of the coexistence curve by watching a progression of phase separations take place over time as the set of prewarmed single-phase samples are allowed to cool. Qual. visualization of the lever rule is demonstrated by showing students the set of samples after equilibration at a temperature well below the critical temperature An interactive Excel spreadsheet is provided to help students connect their observations of the samples with the phase diagram. Quant. and intuitive interpretation of the lever rule can be achieved through height measurements of the biphasic sample layers, leading to immediate graphical determination of the compositions of the isothermal equilibrated phases in the classroom. The set of samples may also be used in an extended classroom or laboratory project to map out the coexistence curve, and advanced students can use the coexistence data to estimate the critical composition of the system, as well as the universal critical exponent β. Finally, preparation of a stable hexaphasic immiscible liquid mixture is described.

Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:132098-59-0) here.

An enantioselective heterogeneous aziridination catalyst is described which is based upon an approach in which cations are anchored by ion-exchange within a microporous or a mesoporous material. The cations can be modified using chiral ligands to form an enantioselective catalyst that is wholly heterogeneous and can be readily reused. Using this approach it is shown that copper-exchanged zeolite HY is a highly active catalyst for the aziridination of alkenes. Modification using bis(oxazolidines) leads to the formation of an enantioselective aziridination catalyst.

Keywords: dicarbonyl radical physiol stability. We’ll tell you more about this compound (cas:141556-42-5).

Organic radicals have been of great academic interest due to their unique reactivity and potential applicability; however, lack of stability and solubility continues to limit their application, especially in physiol. conditions. For example, known aminoxyl radicals have half-life of a few minutes in physiol. conditions due to biol. redox active reagents, while shielding using polymeric or supramol. protecting groups increases their half-life up to several hours. Here the authors designed and synthesized a new small mol. organic radical based on 1,2-dicarbonyl scaffold with exceptional stability. The presented radicals showed superior stability over present organic radicals towards physiol. conditions (half-life of ~3000 h) and even resistant towards chem. reducing, oxidizing, acidic, basic conditions, and high temperature, without addnl. protection.
