Zinc chloride aqueous solution as a solvent for starch.

It is important to obtain starch-based homogeneous systems for starch modification. Regarding this, an important key point is to find cheap, low-cost and low-toxicity solvents to allow complete dissolution of starch and its easy regeneration. This study reveals that a ZnCl2 aqueous solution is a good non-derivatizing solvent for starch at 50 °C, and can completely dissolve starch granules. The ...

Cyanex 302: An extractant for Fe from Chloride Medium

The solvent extraction of Fe from aqueous chloride solution by bis-(2,4,4-trimethylpentyl) monothiophosphinic acid (Cyanex 302, H2A2) dissolved in kerosene has been investigated over a wide range of aqueous acidity as a function of phase contact time, concentrations of Fe, H and Cl in the aqueous phase, Cyanex 302 concentration in the organic phase and temperature. The equilibration time is 50 ...

Structure and dynamics of potassium chloride in aqueous solution.

The structure and dynamics of potassium chloride in aqueous solution over a wide range of concentrations-and in particular beyond saturation-are studied using molecular dynamics simulations to help shed light on recent experimental studies of nonphotochemical laser-induced nucleation (NPLIN). In NPLIN experiments, the duration, t, of the laser pulse (with wavelength 1064 nm) is found to influen...

Pressure-induced unfolding of lysozyme in aqueous guanidinium chloride solution.

The pressure-induced unfolding of lysozyme was investigated in an aqueous guanidinium chloride solution by means of ultraviolet spectroscopy. Assuming a two-state transition model, volume changes were calculated from the slope of free energy vs. pressure plots over a temperature range of 10 to 60 degrees C. Between 25 and 60 degrees C, almost constant volume changes were observed in the transit...

The Structure of Zinc Chloride Complexes in Aqueous Solution

The structure of zinc chloride complexes with different ratios of chloride to zinc, formed in concentrated ZnCl2 aqueous solutions, were determined f rom large-angle X-ray scattering using concentrations of the chloride complexes estimated by complementary Raman spectroscopic measurements. The highest chloro complex, [ZnCl4]~, is tetrahedral with a Zn-Cl bond length of 2.294(4) Ä. The trichloro...
