TL;DR: In this paper, a ternary system water + methyl isobutyl ketone (MIBK) + tert-butyl alcohol (TBA) were experimentally measured at atmospheric pressure over a temperature range of (287.65 to 333.35) K. Binary interaction parameters of NRTL and UNIQUAC models were regressed to correlate the experimental data.
Abstract: Liquid–liquid equilibrium (LLE) data for a ternary system water + methyl isobutyl ketone (MIBK) + tert-butyl alcohol (TBA) were experimentally measured at atmospheric pressure over a temperature range of (287.65 to 333.35) K. The consistency of experimental tie-line data has been tested with Othmer−Tobias and Bachman correlations. Binary interaction parameters of NRTL and UNIQUAC models were regressed to correlate the experimental data. It is concluded that UNIQUAC and NRTL equations are reliable to fit the experimental data with the average root-mean-square deviations of 0.87 % and 0.70 %, respectively.

TL;DR: A mixed matrix modifier of nickel and strontium nitrates was used as a chemical modifier for the determination of selenium in wines by Zeeman electrothermal atomic absorption spectrometry, and the optimum modifier mass established is markedly lower than those presented in the literature.
Abstract: A mixed matrix modifier of nickel and strontium nitrates was used as a chemical modifier for the determination of selenium in wines by Zeeman electrothermal atomic absorption spectrometry. Wine samples were heated on a boiling water bath with small amounts of nitric acid and hydrogen peroxide. For complete elimination of interference, especially from sulfates and phosphates, selenium is complexed with ammonium pyrolidinedithiocarbamate (APDTC), extracted into methyl isobutyl ketone (MIBK), and measured by ETAAS.

TL;DR: In this article, the authors report the new experimental values of densities, speeds of sound, and refractive indices for four binary mixtures: {methyl isobutyl ketone (MIBK)+dimethyl sulfoxide (DMSO) or acetone or acetonitrile, or cyclohexane} over the entire composition range and in the temperatures range (293.15-313.15) K at 10 K intervals and pressure p ǫ = 0.1 MPa.

TL;DR: In this paper, aqueous standards that are much easier and less expensive to dispose of are used with inductively coupled plasma spectroscopy Twenty-one elements are determined from a 300 μg/g base oil solution Extractions of 30W oil, 10W30 oil, and transmission fluid were completed to establish a baseline for subsequent analysis of used oil by this method.

TL;DR: Coulometric generation of H(+) ions by the oxidation of hydrogen dissolved in palladium, in media such as acetone, methyl ethyl ket one, methyl isobutyl ketone, cyclohexanone, acetic anHydride and acetic acid-acetic anhydride mixture, for use in titration of bases, has been investigated.
