TL;DR: In this paper, the authors reported the equilibrium data for the extraction of phenol at 288, 293 and 298 K with n-butyl acetate (NBA), acetophenone (AP), and mixtures of NBA + AP and methyl isobutyl ketone (MIK) + AP.
Abstract: Equilibrium data are reported for the extraction of phenol at 288, 293 and 298 K with n-butyl acetate (NBA), acetophenone (AP) and mixtures of NBA + AP and methyl isobutyl ketone (MIK) + AP. A synergistic behaviour is observed for the system phenol-water-(NBA/AP). Several equations have been used to correlate the experimental data: van't Hoff, Redlich-Kister and other polynomial equations. Reported data were compared with those available in the literature.

TL;DR: In this article, a cost-effective solvent extraction process for recovery of phenol and its hydroxy derivatives from aqueous medium was developed, and four different solvents were selected based on their miscibility with water.
Abstract: A cost-effective solvent extraction process for recovery of phenol and its hydroxy derivatives from aqueous medium was developed. Four different solvents—Tributyl phosphate (TBP), Triphenyl phosphate (TPP), Methyl isobutyl ketone (MIBK) and Oleic acid (OA)—selected based on their miscibility with water. The extraction efficiency (EE) of the selected solvents was studied. A reversed-phase HPLC system connected to an RP, C18 column was used to analyze the aqueous medium to evaluate the performance of the selected solvents. TBP exhibited the best extraction performance, while TPP and MIBK proved to be good when large amount of solvent was used. However, OA was found to be inefficient to extract the solutes under investigation. Interestingly, a different salvation property was observed and elucidated using the solvation theory.

TL;DR: In this article, a one-step synthesis of methyl isobutyl ketone (MIBK) from acetone and hydrogen over metal modified solid base catalysts has been studied at atmospheric pressure and 175-250 °C by using a fixed-bed, integral-flow reactor.
Abstract: One-step synthesis of methyl isobutyl ketone (MIBK) from acetone and hydrogen over metal modified solid base catalysts has been studied at atmospheric pressure and 175-250 °C by using a fixed-bed, integral-flow reactor. Two types of catalysts have been utilized: (1) zeolites modified with palladium (Pd/Kβ, Pd/KZSM-5); and (2) metal oxides modified with sodium and palladium (Pd/Na/MgO, Pd/Na/NaOH/ γ-Al 2 O 3 ). The catalyst properties were characterized by the methods of atomic absorption, temperature-programmed desorption and gas adsorption. Sodium vapor deposition on magnesia, followed by impregnation with tetraamine palladium (II) chloride apparently enhances the catalyst basicity as compared with that of magnesia supported palladium. For catalysts with different supports, the base amount decreases in the order of Pd/Na/MgO > Pd/Na/NaOH/γ-Al 2 O 3 > Pd/KZSM-5 > Pd/Kβ, in accordance with the catalytic activities. As the amount of sodium or palladium in Pd/Na/MgO increases, the catalyst base amount, acetone conversion and MIBK selectivity are also enhanced to a maximum and then decline. Better catalytic results were attained at a higher pretreating temperature of hydrogen on the catalyst. The optimum conditions for this reaction are 0.5%Pd/0.47%Na/MgO pretreated with hydrogen at 400 °C, reaction temperature 200 °C, acetone/hydrogen mol ratio 1, and W/F a 6g.h/mol. Under these conditions, the acetone conversion and MIBK yield are 47.3% and 30.7%, respectively, at 480 min time-on-stream. The reaction network and reaction mechanism for the formation of MIBK are proposed and discussed.
