Effective isolation of succinic acid from aqueous media with the use of anion exchange resins.

The primary objective of this study was to examine the isolation of succinic acid (SA) from aqueous-based solutions through the utilization of adsorption and ion exchange methods. Four kinds of anion exchange resins were employed, two of which were strong basic (Lewatit M-500 and Lewatit M-600), and the other two were weak basic (Lewatit MP-64 and Lewatit MP-62). The impacts of various variables on the efficiency of the process were examined.

Eco-Friendly Approach for the Recovery of Lactic Acid by Complex Extraction.

To meet the growing demand for high-purity lactic acid (LA) for biocompatible and biodegradable polymers, LA recovery by green techniques has been attracting the attention. This study focuses on the evaluation of vegetable oils as organic phase diluents in complex extraction of LA with an aliphatic tertiary amine extractant, trioctylamine (TOA). Eight vegetable oils were tested, and their performances were evaluated individually and compared with those obtained using 1-octanol.

The relation between surface acidity and MoO:AlO ratio on the ternary mixed oxide catalysts for the conversion of propan-2-ol.

In this study, ternary mixed oxide catalysts containing AlO-MoO-MgO and AlO-MoO-WO were prepared with a changing ratio of MoO:AlO between 0.05 and 20.00.
