TL;DR: In this article, an efficient approach for the synthesis of levulinic acid (LA) by converting cellulose in a biphasic system consisting of molten salt hydrate, (LiCl·3H2O) and methyl isobutyl ketone (MIBK) using NbOPO4/HZSM-5 as the catalyst was reported.

TL;DR: In this article, the recovery of levulinic acid from an aqueous solution using a tertiary amine, tri-n-octylamine (TOA), as an extractant in methyl isobutyl ketone (MIBK) was studied at different temperatures (293-333 K).

TL;DR: In this paper, an electrically-driven, high-surface-area solvent extraction system has been conceived and tested, which accomplishes droplet formation, coalescence, and phase separation utilizing a single electric field while operating under countercurrent flow conditions.
Abstract: An electrically-driven, high-surface-area solvent extraction system has been conceived and tested. The system accomplishes droplet formation, coalescence, and phase separation utilizing a single electric field while operating under countercurrent flow conditions. The mass-transport capability of this system has been analyzed by observing the transfer of acetic acid from water (dispersed phase) into methyl isobutyl ketone. Results are reported in terms of the number of theoretical transfer stages per centimeter of column. The emulsion-phase contactor, which has 1.7 stages/cm, outperforms laboratory-scale versions of the York-Scheibel column by a factor of 17 and the Podbielniak centrifugal contactor by a factor of 10. The mass-transfer performance along with the minimal energy requirements of this conceptual device combine to make it an attractive possibility for greatly enhanced solvent extraction operations.

TL;DR: In this paper, the authors investigated the effect of different parameters on recovery of glycolic acid from aqueous solutions by different organic solutions containing Amberlite LA-2, a secondary amine mixture.
Abstract: In this work, extraction of glycolic acid was investigated from aqueous solutions by different organic solutions containing Amberlite LA-2, a secondary amine mixture. The extraction of glycolic acid with Amberlite LA-2 dissolved in six individiual solvents has been measured at 298.15 K. The solvents used were 1-octanol, cyclohexane, isooctane, toluene, 2-octanone, and methyl isobutyl ketone (MIBK). The effect of different parameters on recovery of glycolic acid has been investigated. The investigated parameters were selected as solvent type, amine concentration, and initial acid concentration. To show the effect of these parameters, distribution coefficients (D), loading factors (Z), and extraction efficiency (E) are calculated. The maximum removal of glycolic acid is 79.43 % with MIBK and 0.93 mol·L−1 initial concentration of Amberlite LA-2.
