1. Fundamental research and application of green solvents ( room temperature ionic liquids and aqueous biphasic systems)
Ionic liquids are a new class of international hot field during the last few years, and often said to be green solvents as replace traditional volatile organic compounds (VOCs). Ionic liquids exhibit useful properties such as an extremely low volatility, chemical and thermal stability, nonflammability, and nontoxicity. Due to these unique properties, ILs have been widely used in organic chemical reaction, electrochemical application, separation, molecular self-assemblies, biochemistry. Our most research is summarized below:
(1) Design, synthesis and characterization of the new type ionic liquids and scale-up preparation of ionic liquids. We have synthesized dozens of ionic liquids at laboratory scale. The continuous microwave equipment has been invented and used for the continuous preparation of the ionic liquid. Now the synthesis scale of ionic liquids has already reached hundred kilograms levels, and the platform of the scale-up synthesis and purification of ionic liquid has been established in our laboratory.
(2) Research and application of ionic liquids based advanced functional material. The ionic liquids based infrared absorption material has been designed, prepared and applied in our laboratory, and this research work already obtained the approval of related experts. We had already prepared and characterized some new ionic liquids loaded resin adsorption materials, and the resin carriers include SiO2 sol-gel, XAD-7, PsmimX- and cellulose/chitosan biosorbents et al.
(3) The fundamental study of IL on the separation science and technology of rare earth, hazardous metal ions and organic compounds. The studies were mainly focused on the new IL-based separation systems, such as Cyanex923, N1923, DEHEHP, Cyphos@104 et al extractants dissolved in [Cnmim]PF6/Tf2N or biodiesel as organic extractive systems for the extraction of rare earth or related metal ions. The application of the IL loaded resin material prepared in above item 2 for the adsorption of metal ions including rare earth and environmental hazardous Cr(IV), Ni(II) et al was also studied. At the same time, our lab studied the separation of acetate-ethanol azeotropic mixture, and the enrichment of aromatic compounds such as nitrobenzene and phenol and so on using IL and Aqueous Biphasic Systems from their aqueous solutions, and invented an easy, clean and high efficiency method for recovery the aromatic compounds from polluted water.
2. Application of green technology and clean process on the separation of rare earth and related metal resources
Facing to the demand and development of the country to the resources and environment, as well as major strategic, the comprehensive utilization of the important resources of valuable metal elements such as rare earth mine, cobalt-nickel mine, vanadium mine and oil shale ash are being conducted. From fundamental study of complex extractive systems to the industry practice, the clean technology was developed to solve core technology.
(1) The current pollution produced in the processes of rare earth metallurgy in Panxi of Sichuan mainly comes from Th(IV) and F(I) in the rare earth mine. It is important to utilize and recycle the valuable elements such as Th and F and so on. At the same time, as important nuclear materials, the potential utilization value of Th(IV) is being concerned from both government and market . We have studied several separation systems based on the extraction of Ce(IV), Th(IV) and RE(III) using [C8mim]PF6 with N1923 and DEHEHP, and the new ILs-based separation technique on Sichuan Bastnasite has been successful at bench scale, and more evaluation for this system is being conducted.
(2) Commercial utilization of Fe, Al and rare earth metal elements enriched in the oil shale ash is receiving wide attention since billion tons of oil shale in Jilin province was found and exploited. Reserve of rare earth resources in oil shale can be 1450,000 tons of rare earth in oil shale of Jilin province. In order to develop economy of Jilin province and solve the shortage of mineral resources and environmental protection, it is important to study and utilize the oil shale resources and recovery the rare earth. We are investigating the enrichment of the rare earth from oil shale ash, and developing a new valuable promising technology under the support of “863 program” from China Ministry of Science and Technology.
