There are a lot of research programs focusing on the development new solvents for carbon dioxide capture. The most important priority should be reducing energy consumption needed at regeneration step, but minimizing solvent degradation and its corrosivity is also considered as priority. In this research, aqueous blends 2-amino-2-methyl-1-propanol (AMP: 1 kmol·m−3) 1-amino-2-propanol (MIPA: 0.1–...

The ultrasonic velocity (V), density (ρ) and viscosity (η) measurements of Hydroquinone in n-propanol and iso-propanol have been carried out for the study of solute-solvent interaction. Experimental data have been used to calculate the isentropic compressibility (bs), intermolecular free length (Lf), specific acoustic impedance (Z), molar sound velocity (R), relative association (RA) solvation ...

Aqueous mixtures of 1-propanol have been investigated by high-energy synchrotron X-ray diffraction upon cooling. weighted total scattering structure factors 6 mixtures, from 8 mol% to 89 alcohol content, as well that pure are reported room temperature down the freezing points liquids. Molecular dynamics simulations performed, in order interpret measured data. The all atom OPLS-AA potential mode...

LaMnO3 and LaMnO3/ZSM-5 nano catalysts were synthesized by Pechini method and their physical-chemical properties were characterized using XRD, FTIR, SEM-EDX, UV-vis DRS, BET surface area and TPR. The correlation between characteristic properties and activity of catalysts were investigated. The catalytic performance of the catalysts was evaluated in combustion of 2-propanol...

Specific enzymic formation of the I)g isomer" of I-amino-2-propanol, a part of the vitamin B12 molecule, has not yet been reported. KRASNA, ROSENBLUM AND SPRINSON z, using growing cultures of Streptomyces griseus, found that L-E15NJthreonine is effectively incorporated into the aminopropanol moiety of vitamin B12 and suggested that the amino alcohol might be formed by decarboxylase activity. A ...

BACKGROUND With the increasing consumption of fossil fuels, the question of meeting the global energy demand is of great importance in the near future. As an effective solution, production of higher alcohols from renewable sources by microorganisms has been proposed to address both energy crisis and environmental concerns. Higher alcohols contain more than two carbon atoms and have better physi...

Alcoholic fuels have recently come to light as a sustainable source for powering today’s vehicles. Various studies investigated the effects of alcoholic on engine efficiency and emission characteristics. However, scarce literature is available their lubricant. Therefore, propanol-gasoline fuel mixtures, with concentrations 9% (P9) 18% (P18) propanol, were made compare characteristics lubricatin...

Recent findings indicate that the buffer 2-amino-2-methyl-1-propanol, widely used in clinical measurement of alkaline phosphatase activity, contains an impurity that inhibits the activity of the enzyme. Analysis of several lots of 2-amino-2-methyl-1-propanol has demonstrated the presence of a material, the concentration of which correlates well with alkaline phosphatase activity. Mass spectral ...

In this paper, we present indirect methods to define the change in rates of hydrolysis and condensation reactions a silica oxide network formed (3-glycidoxypropyl)methyltriethoxysilane (GPTMS) (3-aminopropyl)triethoxysilane (ApTEOS), which was strongly dependent upon nature solvent used reaction environment, such as methanol, ethanol, propanol, butanol acetone. Electron microscopy (SEM), focuse...
