TL;DR: In this paper, the dielectric constants of binary mixtures of MIBK, an extractant used in nuclear energy industry, with six apolar solvents were measured at 455 kHz, and the data were used to evaluate the Eyring structural parameter, G*, in these systems to assess the nature of nonspecific solute-solvent interaction.
Abstract: Dielectric constants of binary mixtures of MIBK, an extractant used in nuclear energy industry, with six apolar solvents ie benzene, dioxane, cyclohexane, carbon tetrachloride, p-xylene and n-heptane have been measured at 455 kHz The data are used to evaluate the Eyring’s structural parameter, G*, in these systems to assess the nature of non-specific solute-solvent interaction The value of G* is found to be influenced by the nature of the solvent

TL;DR: In this paper, a method for the fluorometric determination of gallium in aluminum metal is presented which involves extraction with the methyl isobutyl ketone (MIBK) of the gallium 8-quinolinethiolate complex.
Abstract: A method for the fluorometric determination of gallium in aluminum metal is presented which involves extraction with the methyl isobutyl ketone (MIBK) of the gallium 8-quinolinethiolate complex. The extracted complex has a greenish-yellow fluorescence, with an emission maximum at 505 nm. The maximum fluorescence intensity is obtained at a pH of the initial aqueous phase of around 3.3; the fluorescence remains stable for at least 2 hr. When 50 ml of a sample aqueous solution containing gallium and 0.2 ml of a 0.2% 8-quinolinethiol solution is subjected to extraction with 10 ml of MIBK, the quantity of gallium which can be present for determination in the sample solution amounts to 1 to 30 μg. For the removal of the interfering effects of zinc, cadmium, copper, and nickel on the fluorometric determination, gallium was extracted with isopropyl ether from a 7 M HCl solution. The relative error of this method was 5% for 0.019% gallium in aluminum metal.

TL;DR: In this paper, a low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed, which is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor.
Abstract: A low-pressure one-step gas-phase process for the production and recovery of methyl isobutyl ketone (MIBK) is disclosed. One-step gas-phase synthesis of MIBK from acetone and hydrogen over nano-Pd/nano-ZnCr 2 O 4 catalyst at atmospheric pressure is used as an example. The said process is designed to recover the additional heat associated with the reactor effluent via heating acetone feed and recycle (mixed acetone) before entering the reactor. A compressor is introduced to the gas-phase process to increase slightly the reactor effluent pressure before this effluent is cooled and fed to a flash drum. The compressed reactor effluent is used to preheat hydrogen feed and recycle (mixed hydrogen) before entering the reactor. The separation scheme of low-pressure one-step gas-phase process comprises of several distillation columns used for MIBK separation and purification.
