Density and Volume Properties of the Chlorohydrin + 2-Methoxyethanol + 1,2-Dimethoxyethane Ternary Solvent System at Different Temperatures

The density of the Chlorohydrin (CE) + 2-methoxyethanol (ME) + 1,2-dimethoxye- thane (DME) ternary mixtures has been measured at different temperatures ranging from 鈭10 to 80 掳 C, and over the entire composition range. The experimental data have been used to check the validity of some relationships accounting for the dependence of the density on temperature and composition domains. Starting from the primary data, some derived quantities, such as excess molar volumes V E , partial molar volumes $$\bar V_{\text{i}}$$ and partial excess molar volumes $$\bar V_{\text{i}}^E$$ , have been obtained. In these mixtures, V E is always positive for the [CE(1) + ME(2)] binaries, while it is generally negative at all other experimental conditions, showing the greatest deviations along the binary axes corresponding to the binary subsystems in the sequence [CE(1) + DME(2)] < [CE(1) + ME(2)] < [ME(1) + DME(2)]. The results are compared and discussed to in terms of changes in molecular association and structural effects in these solvent systems.

Modification of Activated Carbon Fiber by Metal Dispersion and Surface Functionalization for the Removal of Chlorohydrin

ABSTRACT Nickel-impregnated phenolic resin precursor-based activated carbon fiber (ACF) was functionalized with pyridine and investigated for the adsorptive removal of Chlorohydrin. Adsorption tests were carried out under flow conditions for different gas flow rates, solute concentrations, and temperatures in a perforated tubular adsorber. Various analytical and spectroscopic techniques, including X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), and CHNSO
