We investigated the thermal properties of several imidazolium salts using DSC and TGA/SDTA data. Many of these salts are liquids at sub-ambient temperatures. These ionic liquids form glasses at low temperatures and have minimal vapor pressure up to t

The specific ionic conductivity, dynamic viscosity, and electrochemical stability of several imidazolium salts are reported as neationic liquids and their solutions in several organic solvents. The temperature dependence of conductivity and viscosity

Hexahydropyrimidines N,N-bridged by a chain of n methylene groups (1,(n+2)-diazabicyclo[n.3.1]alkanes) adopt out,out (axial,axial) structures for n=2, 3, and 4. When n=5, the photoelectron spectrum shows evidence of the presence of some of the out, i

Electrolytes based on 1-ethyl-3-methylimidazolium cation (EMI{sup +}) and either the hexafluorophosphate (EMIPF{sub 6}) or tetrafluorborate (EMIBF{sub 4}) anion in organic alkyl carbonate solvents have been evaluated for use in electrochemical capaci
Publisher Summary This chapter discusses the laser pyrolysis of entrained stream of coal particles. The simplicity of pyrolysis as a basis for deriving liquid and gaseous fuels from coal is offset by the problem of poor yields and product quality. Ef

The two anions bis(trifluoromethylsulfonyl)imide (Im) and bis(perfluoroethylsulfonyl)imide (Beti) display similar passivation on aluminum in solvent-free ionic liquids. The addition of 10% propylene carbonate to the ionic liquids EMIIm and EMIBeti (E

The catalytic activation of hydrocarbon C–H bonds is a fundamental process in heterogeneous catalysis. Although C–H bonds are readily activated on certain metal surfaces, the nature of the catalytic sites is still not understood. Catalytic C–H
