Novel protic ionic liquids (PILs) and low melting mixtures (LMMs) have been synthesized based on green components, cheap sources, the high purity, and easy way of preparation. PILs include [Im][For], [Im] [Ace], [Im][Pro], [Im][But], and [Im][Pen]. LMMs include [ImCl][EG], [ImCl][Gly], [ImCl][PEG], [ImCl] [ETA], and [ImCl][carbohydrate] + DMSO. These solvents contain imidazolium/imidazolium chloride as a cation/salt. NMR spectroscopy was used to analyze the structures of solvents. Melting points, and thermal stabilities were measured via thermal analyses. We were looking to synthesize new DESs with imidazolium chloride (ImCl), Due to lack of observation the melting points for mixtures of ImCl + hydrogen bond donors (HBDs), these mixtures were called low melting mixtures (LMMs) in this work. The mixtures of PILs/LMMs with molecular solvents showed good implications for homogenous and heterogenous systems which can be used for separation goals. Solubilities of carbohydrates, and some amino acids were tested in pure and mixed of ILs with molecular liquids. Adding DMSO to ILs/LMMs increased the dissolution of carbohydrates. As well, adding water to ILs had a remarkable effect for increasing the solubility of amino acids. (C) 2021 Published by Elsevier B.V.
