Dominant Association Species in Binary Mixtures of Methanol, Ethanol and Propanol in Nonpolar Solvents

The molecular associations in the binary mixtures of (methanol/solvent), (ethanol/solvent) and (propanol/solvent) were studied using NMR, FTIR and VLE data at different temperatures. The activity coefficients as the most important quantities representing the mixture deviation form ideal behavior were evaluated by using various association models to express the physical and chemical contribution...

Bacillus Amyloliquefaciens Alpha-amylase Inhibition by Organic Solvents: A Study on Methanol, Ethanol and Propanol

Alpha-amylase is widely used as an industrial enzyme, and a therapeutic target for which inhibitors are designed. Organic solvents are used to dissolve various compounds that would be studied as moderators of alpha-amylases, but they could themselves affect enzyme activity and stability. Methanol, ethanol and propanol are simple alcohols that may be commonly used to this end, and their effect h...

Infrared Spectra of Methanol, Ethanol, and rz-Propanol

The infrared absorption spectra of methanol, ethanol, and n-propanol have been measured with prism instruments. Studies have been made of the vapors and of several dilute solutions. The methanol spectra, between 2 to 15 microns, prpvided a direct comparison with the other two alcohols and confirmed earlier work on the existence of a number of lowintensity bands. The two other alcohols were stud...

Evaluation of Ethanol and N-propanol in Victims

Background: Blood alcohol concentration is a major factor in forensic analysis in criminal and civil litigation. Along with ethanol, other volatile compounds such as n-propanol are produced as products of putrefaction. The aim of this study is the evaluation of ethanol and n-propanol in postmortem blood. Methods: A case-control study was done on 300 blood samples obtained from cadavers that...
