Quality control of liquid raw materials arriving on an industrial manufacturing site is typically performed in a dedicated laboratory using time- and chemicals-consuming analytical methods. Herein, we report the successful development handheld near-infrared spectroscopy method for rapid, low-cost testing organic solvents. Our methodology enables classification solvents with 100% accuracy quanti...

In this study, NRTL and UNIQUAC thermodynamic models were used to predict the composition of ternary mixtures of solvents+ m/o/p-cresol+ water in organic and aqueous phases. Various solvents are used for the separation of cresols from water. In this study, methyl propyl ketone, methyl isopropyl ketone, methyl butyl ketone, and methyl isobutyl ketone solvents were investigated. Intermolecular in...

New experimental solubilities and tie line data for ternary mixtures containing two completely miscible binaries and one nonmiscible binary as part of a program to determine the thermodynamic properties of a series of ternary and binary systems with HMDS [1–3] are given. Hexamethyldisiloxane 99.5%, NMR grade, 2-butanone 99.5%, HPLC grade (MEK), 3-pentanone 99% (DEK) and dimethyl sulfoxide 99.9%...

In this paper, a description of olfactory anatomy is presented, followed by a brief review of modern procedures for testing olfactory function. Information from the sole study which has quantitatively examined olfactory function in patients with apparent multiple chemical sensitivity (MCS) is presented. In essence, this study suggests that MCS is associated with increased nasal airflow resistan...

The capability of physiologically based pharmacokinetic models to incorporate age-appropriate physiological and chemical-specific parameters was utilized to predict changes in internal dosimetry for six volatile organic compounds (VOCs) across different ages of rats. Typical 6-h animal inhalation exposures to 50 and 500 ppm perchloroethylene, trichloroethylene, benzene, chloroform, methylene ch...
