In respect to electrochemical application, ionic liquids seem to be very attractive forelectro sedimentation of metals. A wide range of potentials wherein they are stable, allows oneto carry out sedimentation of metals with standard electrode potential lower – 1V at roomtemperature, what is impossible from aqueous solutions. In this connection, searching for newmolecular structures of the ionic liquids with high electro conductivity and low viscosity, withwide electrochemical window and thermal stability represents indubitable interest. One ofperspective directions of researches consists in systematic synthesis of alkoxy-alkyl-amine ionicliquids which can be synthesised from accessible and cheap raw material. Surely, physical andchemical properties of this class compounds unknown in literature, while interest to catalyticapplication of ionic liquids is also growing. In particular, Chinese authors have first preparedacetate 3-methoxylpropylamine and used as catalyst for reactions Anry and Knevenagel [1].In our work, electro conductivity of acetate methoxylpropylamine was found to be4.0 мSм/cm. To assign signals in NMR spectra, along with acetate 3-methoxylpropylamine,we have synthesised trifluoroacetate 3-methoxylpropylamine. In NMR13 С spectrumof 3-methoxypropylamine trifluoroacetate, among the strongest signals occurrence multipletis revealed at 39,5 ppm. (solvent, DMSO), two quartets, apparently, concerning totrifluoroacetate to an ion at 117,2 ppm. (СF 3 ) and 159,5 ppm. (С=О) and four singletat 27,3 ppm., 37,0 ppm., 58,0 ppm and 69,1 ppm, concerning accordingly to one methyl groupand to three methylene groups.ESR spectrum of VO(acac) 2 in 3-methoxylpropylamine acetate and trifluoroacetate as distinctfrom VO(acac) 2 in absence of solvent has revealed superfine structure.Acknowledgement.
