TL;DR: Experimental mutual solubility and tie-line data were determined for three ternary liquid-liquid systems containing water, ethanol, and amyl acetate, benzyl alcohol, and methyl isobutyl ketone at 298.15{Kappa} in order to obtain their complete phase diagrams and determine which is the most suitable solvent for extraction of ethanol from aqueous solutions as discussed by the authors.
Abstract: Experimental mutual solubility and tie-line data were determined for three ternary liquid-liquid systems containing water, ethanol, and amyl acetate, benzyl alcohol, and methyl isobutyl ketone at 298.15{Kappa} in order to obtain their complete phase diagrams and to determine which is the most suitable solvent for extraction of ethanol from aqueous solutions. Tie lines were determined correlating the density of the binodal curve as a function of composition and the plait points using the Othmer and Tobias method. The experimental data were also correlated with the UNIFAC group contribution method. A qualitative agreement was obtained. Experimental results show that amyl acetate is a better solvent than methyl isobutyl ketone and benzyl alcohol.

TL;DR: An improved energy-saving fuel additive for diesel engines and gasoline engines which comprises separate compositions which raise the flash point from about 6' to 29'C was proposed in this article.
Abstract: An improved energy-saving fuel additive for diesel engines and gasoline engines which comprises separate compositions which raise the flash point from about 6` to 29`C. In the case of the diesel additive, the following formulation is preferred: Elemental iron .01%, Methyl isobutyl ketone 5.0%, Picric acid 1.5% Normal butyl alcohol 20.0%, Kerosene 73.0%, Nitrobenzene .08%, Primene 81R .05%. The composition of the agent for gasoline to high flash point is somewhat different and may be noted as follows: Copper cabonate hydroxide .02%, Methyl isobutyl ketone 5.0%, Normal butyl alcohol 20.0%, Kerosene 73.0%, Picric acid 1.5%, Nitrobenzene .08%, Primene 81R .05%.

TL;DR: In this paper, the authors treated methyl isobutyl ketone (MIBK) by a commercial catalyst, Pt/γ-Al2O3, in an isothermal fixed bed differential reactor and observed the effects of O2 and MIBK content in carrier gas on the catalysis's reaction rate.

TL;DR: The observed loss patterns, if evaluated in relation to some key parameters like concentration or compound type, suggest the possibility that the sorptive loss of target compounds in storage media can occur in a predictable manner.
Abstract: In this study, the sorptive loss patterns for volatile organic compounds were evaluated by gaseous standards containing 13 compounds (benzene, toluene, styrene, p-xylene, methyl ethyl ketone, methyl isobutyl ketone, isobutyl alcohol, butyl acetate, acetaldehyde, propionaldehyde, butyraldehyde, isovaleraldehyde, and valeraldehyde). The gaseous standards, prepared initially at two contrasting concentration levels (40 and 4000 ppb) in a polyester aluminum bag, were measured after two consecutive transfers into empty bags. It indicates that the percent loss patterns, if assessed for all 13 target compounds, are affected most sensitively by the initial concentration levels of samples to yield 2.62 ± 2.22% (at 40 ppb) and 9.57 ± 6.74% (at 4000 ppb). Moreover, the sorptive loss patterns at high concentration samples (4000 ppb) tend to increase in relation with increasing molecular weight of target compounds, although such pattern disappears in low concentration samples (40 ppb). The observed loss patterns, if evaluated in relation to some key parameters like concentration or compound type, suggest the possibility that the sorptive loss of target compounds in storage media can occur in a predictable manner.
