“…N-alkylpyrrolidonium cation structure in ionic liquids can improve their solvent properties and specific separation characteristics over conventional ionic liquids. Moreover, the use of alkyl pyrrolidones in the design of new ionic liquids will greatly reduce their production costs and, in case of vinylpyrrolidone, will also allow the inexpensive synthesis of the polyelectrolyte [13] . With this knowledge, we designed a new family of ionic liquids based on N-methyl-2-pyrrolidone that was modified by the alkyl chains, which have benign conductivity, low viscosity and biocompatibility; and, as well as the general surfactants, they have surface activity, such as decreasing surface tension and aggregation behaviour.…”

Ionic liquids have many unique properties as a new and remarkable class of environmental benign solvents, which promises widespread applications in industry and other areas. However, the ionic liquids with surface activity are rarely reported. In this work, a series of novel ionic liquids was synthesized by using N-methyl-2-pyrrolidone and alkyl bromide. The physical properties of this family of ionic liquids have been characterized, which shows that these compounds have ionic liquids characteristics, surface activity and biocompatibility. surface activity, ionic liquids, N-methyl-2-pyrrolidone, biocompatibility In recent years, ionic liquids have attracted considerable interest, and a number of reviews that cover the history, properties and use of ionic liquids are available. Unlike conventional molten salts, ionic liquids are salts with low melting points (<100℃). Ionic liquids are mainly composed of organic cations and anions which are inorganic groups or organic groups. However, the ionic liquid field continues to be extensively dominated by imidazolium salts with fluorine containing anions. Among the more useful properties of ionic liquids are the following: (1) they are relatively nonvolatile, which means they do not produce atmospheric volatile organic carbon (VOCs) and can be used in low-pressure (vacuum) environments; (2) they are nonflammable, the most complex and versatile of solvents in that they have the ability to interact via hydrogen bonding, p-p, n-p, dispersive, dipolar, electrostatic, and hydrophobic interactions and they are good solvents for a wide variety of organic and inorganic compounds; (3) they have physicochemical properties (such as the solvency for inorganic compounds, water, organic compounds and polymer) that can be altered/controlled by judicious selection of the cation and/or anion [1][2][3] . Thus far, current new ionic liquids design and their physicochemical properties in catalysis, solvency and electrochemistry application are the focus in research. However, few articles reported the surface activity of ionic liquids [4][5][6] ; many ionic liquids were reported without surface activities and with high viscosity, which limits their application in more extensive field [7,8] .Lactam-structure compounds existing in nature are well known, such as penicillin and Skin Moist Factor L-pyrrolidone-5-carboxylic acid. Moreover, 2-pyrrolidone exists in nature as itself or the middle product of metabolism. N-methyl-2-pyrrolidone is widely used as "super solvent" in industry and other areas because of its super solvency. Thereby, ionic liquids composed of lactam-structure should have excellent solvency and biocompatibility. MacFarlane et al. have investigated an interesting new family of RTILs, based on the N-alkylpyrrolidinium cation and three different anions, bis (triflioromethane sulfonyl)imide, tetrafluoroborate and dicyanamide, for applications in electrolytes and solvents [9][10][11][12] . Demberelnyamba et al. first synthesized RTILs based on N-vinyl-2-pyrrolidinonium cation cont...

“…Recently, considerable interest has been manifested in the use of room temperature ionic liquids as battery electrolytes and green-solvent alternatives owing to their unique electrochemical and physical properties [1][2][3][4][5][6][7][8][9][10]. Ionic liquids are liquids that are comprised entirely of ions like ionic melts which are produced by heating normal inorganic salts.…”

Biphasic and multiphasic processes have emerged as effective methods to reduce the amount of volatile organic solvents used in the manufacture of chemicals. In this article some of the research conducted in my laboratory in this domain utilizing ionic liquids is described. Other dimensions to our research interests in ionic liquids are also discussed including their conversion to porous nanomaterials.
