A new low transition temperature mixture (LTTM) formed by choline chloride+lactic acid: Characterization as solvent for CO2 capture

Potassium Carbonate as a Salt for Deep Eutectic Solvents

“…The most evident event in the thermogram was the glass transition slope that was used to estimate the glass transition temperature for the system. This phenomenon was recently observed by [17] using previously reported DES system of Choline Chloride-lactic acid in which glass transition was observed rather than freezing for a wide range of ratios used in their work. The group called the mixture Low Transition Temperature Mixture (LTTM).…”

Solubilities of carbon dioxide in the eutectic mixture of levulinic acid (or furfuryl alcohol) and choline chloride

“…However, ionic liquids still have several shortcomings including high price, complicated technology for production and purification, uncertain toxicity and poor biodegradability [12]. Hopefully, the emerging deep eutectic solvents (DESs), known as an advanced generation of ILs, seem to be good candidates [13].…”

Physicochemical properties of betaine monohydrate-carboxylic acid mixtures

“…DES are formed by mixing a quaternary ammonium salt (such as choline chloride, betaine) with hydrogen bond donor (HBD) compound, such as an alcohol, organic acid, sugar or amino acid [2]. DES were applied in catalysis, CO 2 removal, and metal ion adsorption, and extraction of organic and inorganic compounds [3][4][5][6][7].…”
