Biodiesel Purification by Solvent-Aided Crystallization Using 2-Methyltetrahydrofuran

Wan Nur Aisya Wan Osman et al.

Summary: This study optimized the parameters of solvent-aided crystallization (SAC) using 1-butanol as an assisting agent for the purification of biodiesel. 2-Methyltetrahydrofuran (2-MeTHF) was used as an alternative solvent. The study aimed to improve the purification process of biodiesel and achieve a higher purity. Experimental works were conducted to produce crude biodiesel through transesterification and SAC was performed to purify it. The results showed that the optimum values for coolant temperature, cooling time, and stirring speed were -4 degrees C, 10 min, and 210 rpm, respectively. The assisting solvent 2-MeTHF significantly affected the process parameters for producing purified biodiesel according to the standard requirement.

Copper-Free Halodediazoniation of Arenediazonium Tetrafluoroborates in Deep Eutectic Solvents-like Mixtures

Giovanni Ghigo et al.

Summary: Deep eutectic solvent (DES)-like mixtures based on glycerol and different halide organic and inorganic salts have been successfully used as new media for copper-free halodediazoniation of arenediazonium salts. The reactions are conducted without the need for metal-based catalysts, at room temperature, and in a short period of time. Pure target products are obtained without the requirement of chromatographic separation. The solvents have been fully characterized and a computational study has been presented in order to understand the reaction mechanism.

Enhanced Extraction Efficiency of Flavonoids from Pyrus ussuriensis Leaves with Deep Eutectic Solvents

Jong Woo Lee et al.

Summary: The study synthesized deep eutectic solvents using choline chloride and dicarboxylic acids and used it for the extraction of flavonoid components from Pyrus ussuriensis leaves. The optimal extraction conditions were determined to be at 30 degrees C using DES at a concentration of 30.85 wt.%, resulting in 217.56 mu g/mL of flavonoid content. The results showed that the CC and GA-based DES extraction process effectively improved the yield of flavonoids from PUL.

Neutron Total Scattering Investigation of the Dissolution Mechanism of Trehalose in Alkali/Urea Aqueous Solution

Changli Ma et al.

Summary: The atomic picture of cellulose dissolution in alkali/urea aqueous solution is investigated using trehalose as the model molecule and total scattering as the main tool. The study reveals that the hydration shell of trehalose has a layered structure, with smaller alkali ions penetrating glucose rings and larger urea molecules interacting with hydroxide groups to form complexations. The solubility of alkali aqueous solution for cellulose decreases with the alkali cation radius. These findings are important for the design of greener solvents for cellulose.

Prediction of pH Value of Aqueous Acidic and Basic Deep Eutectic Solvent Using COSMO-RS σ Profiles' Molecular Descriptors

Manuela Panic et al.

Summary: The aim of this study was to develop a simple and easy-to-use model for predicting the pH values of deep eutectic solvents (DESs). By measuring and mathematically interpreting the pH values of 38 different DESs, and using models such as multiple linear regression, piecewise linear regression, and artificial neural networks, it was found that piecewise linear regression and artificial neural networks can predict the pH values of DESs well.

Ionic Liquid Extraction Behavior of Cr(VI) Absorbed on Humic Acid-Vermiculite

Hsin-Liang Huang et al.

Summary: Cr(VI) is a toxic metal released into soil from mining, electroplating, and smelting operations, and its removal is crucial to protect ecosystems. Vermiculite, with high cation exchange capacity, is a beneficial adsorbent for extracting Cr(VI) in situations of metal pollution during the remediation process. An ionic liquid, [C(4)mim]Cl, has shown efficiency in extracting Cr(VI) from contaminated sorbents in soil remediation.
