Abstract
An application of the novel ionic liquid as extractant for extracting organic substance from water is disclosed. Its advantages are high effect and no loss of extractant.
Description
Technical field:
The present invention relates to a kind of being used for from the novel ion liquid of aqueous solution extraction organic substance.
Background technology:
Ionic liquid (Ionic liquids) is found in 1914, but up to 1992, Wikes leader's research group synthesized low melting point, anti-hydrolysis, stable strong 1-ethyl-3-methyl imidazolium tetrafluoroborate ionic liquid ([emim] BF
4), developed the ionic liquid of a series of excellent propertys subsequently again, just make ionic liquid research develop rapidly.Ionic liquid is compared with ionogen with traditional organic solvent, and have a series of outstanding advantages: (1) does not almost have vapour pressure, and is non-volatile; Colourless, odorless; (2) has bigger equilibrium temperature scope, the electrochemical stability potential window of better chemical stability and broad; (3) have the good solubility energy, with inorganic substance good solute effect is arranged all much organic.(4) ion liquid character has controllability, by changing ion liquid zwitterion collocation, can obtain the ionic liquid of different effect of extracting.
Existing a lot of ionic liquids are used for the report of extracting and separating both at home and abroad.Rogers etc. have measured several aromatics at water and ionic liquid 1-butyl-3-Methylimidazole hexafluorophosphate ([bmim] PF
6) in partition ratio, propose ionic liquid and be expected to substitute traditional easy volatile organic solvent and be used for extracting and separating.Wei Guor-Tzol etc. use [bmim] PF
6From aqueous phase extraction Ag
+Deng metal ion, obtained extraordinary effect of extracting.At present be applied to used ionic liquid in the isolating report of liquid-liquid extraction and mostly be common hydrophobic ionic liquid as [bmim] PF at ionic liquid
6Deng, such ionic liquid has the raw materials cost height, the complicated and shortcomings such as hydrolysis easily, poor heat stability of synthesis step, and the research and development that therefore is used for the isolating novel ion liquid of liquid-liquid extraction is an important directions of present ionic liquid research.Employed ionic liquid is recent synthetic novel ion liquid among the present invention, and the research that is applied to extracting and separating is not seen in report as yet.
Summary of the invention:
The present invention proposes a kind of novel ion liquid as organic substance in the extraction agent extraction water.
This ionic liquid has that raw materials cost is low, synthesis step is simple, productive rate is high, stable in properties, advantage such as facile hydrolysis not, for the effect of extracting of organic substance in the water than [bmim] PF
6Better etc. conventional ion liquid.
