The viscosity (9.34–405.92 mPa·s) and absorption capacity (0.4394–1.0562 g·g−1) of (1-ethyl-3-methylidazolium trifluoroacetate + triethanolamine) binary blends atmospheric pressure in the temperature range of 303.15–343.15 K and at different mole fractions of [EMIM] [TFA] have been carried out. The molar fraction of [EMIM] [TFA] dependence of the viscosity and absorption capacity was demonstrated. The addition of a small amount of [EMIM] [TFA] into TEA led to rapidly decreased rates of binary blends’ viscosity and absorption capacity. However, the viscosity and absorption of binary blends did not decrease significantly when [EMIM] [TFA] was increased to a specific value. Compared with the molar fraction of the solution, the temperature had no obvious effect on viscosity and absorption capacity. By modeling and optimizing the ratio of viscosity and absorption capacity of ([EMIM] [TFA] + TEA), it is proven that when the mole fraction of [EMIM] [TFA] is 0.58, ([EMIM] [TFA] + TEA) has the best viscosity and absorption capacity at the same time. In addition, at 303.15 K, ([EMIM] [TFA] + TEA) was absorbed and desorbed six times, the absorption slightly decreased, and the desorption increased.

To well know the properties of ionic liquid mixtures, the viscosity of the binary mixtures containing the methylbenzene and imidazole ionic liquids (1-butyl-3-methylimidazolium tetrafluoroborate [Bmim][BF4] or 1-butyl-3-methylimidazolium hexafluorophosphate [Bmim][PF6]) were measured. Within the temperature range from 298.15 K to 308.15 K, the viscosity of the four binary systems decreased sharply as the increase of temperature. The viscosity decreased slowly in the temperature range from 308.15 K to 338.15 K. The viscosity also decreased with decreasing of the mole fraction of ionic liquid. The viscosity of methylbenzene in the imidazole ionic liquids was in sequence: [Bmim][BF4] < [Bmim][PF6]. The experimental viscosity values had been correlated using the binary parameters of Vogel-Fulcher-Tamman equation.

The new room temperature ionic liquid 1-allyl-3-methyl-imidazolium bicarbonate [amim][HCO3] was synthesized. The viscosities and conductivities of [amim][HCO3] + water and + ethanol binary mixtures were determined in the temperature range from 273.15 K to 343.15 K, and the mole fraction of the solvents in the mixtures was in the range of 0 to 0.75 for water and 0 to 0.55 for ethanol. The conductivities of the mixtures increased with increasing concentration of the solvents and temperature in the solvent concentration range studied. The viscosities of the mixtures decreased with increasing temperature.

The pH value of binary mixtures containing N,N-dimethylformamide (DMF) and 1-butyl-3-methylimidazolium tetrafluoroborate ([Bmim][BF4]) and 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF6]) ionic liquids over the range of N,N-dimethylformamide mole fraction from (0.1 to 0.9) and temperature range from (293.15 to 338.15) K were measured. The range of pH values of N,N-dimethylformamide and [Bmim][BF4] and [Bmim][PF6] were from (3.42 to 6.50) and (6.98 to 9.74), respectively. Comparison showed that the pH of N,N-dimethylformamide in the two ionic liquids was in sequence: [Bmim][BF4] < [Bmim][PF6] at the same conditions. The temperature dependency of the pH value was correlated using an empirical equation. The correlations gave satisfactory results.

The behaviour of several zeolites as catalysts for the title reaction has been investigated by means of a continuous flow microreactor. Runs performed at atmospheric pressure indicated that at 423 K the completely protonic forms of the zeolites catalyze just the isomerization reaction. In the case of Y zeolites, oligomerization occurs only over the partially decationated samples, in the temperature range between 373 and 423 K and W/F between 0.2 and 22 gcath/g1-but, to an extent which depends on the reaction conditions. Most of the catalysts were tested also under pressure (4.05 MPa) at 423 K. The protonic forms of Y and ZSM-5 zeolites seem promising catalysts in terms of both conversion and selectivity to oligomers. The 1-olefins account for 30% of the entire olefinic mixture. The octenes, which account for 70% of the liquid mixture, are mostly formed of dimethylhexenes. Trimers are also formed during the reaction and, in the very particular case of H[B]ZSM-5, tetramers are produced.
