【Abstract】 Domestic and abroad advances in the synthesis of hydrophobic deep eutectic solvent(DES)and their applications was reviewed.Based on their molecular structures of such hydrophobic deep eutectic solvents as terpenes,quaternary ammonium salts,long chain fatty acids and choline chloride,contributions of various groups in hydrogen bond donor(HBD)and hydrogen bond acceptor(HBA)molecules on their lipophilicity and hydrophobicity were compared and analyzed.Physichemical properties of different hydrophobic DESs,such as melting point,density,viscosity,refractive index or electrical conductivity and the DES′s solubility in water,were described,respectively.The DES′s applications in such extraction fields as aqueous metal ion,insecticides and dyes in aqueous solution,bioactive compounds in natural plants and liquid-liquid microextractions in analytic chemistry were given and further prospect was expected.更多还原
