Supported Ionic Liquids

Abstract. A series of mesoporous materials supported ionic liquids were prepared and tested as effective and practical catalysts for the synthesis of 2,4,5-triaryl-1H-imidazoles. The effects of type of catalysts, catalyst amount, and catalyst stability have also been investigated in detail, the catalyst Ti-SBA-15@ILTsO exhibited excellent activity in excellent yields of 92 % ~ 99 % with low catalyst amount at room temperature within 1 h. In addition, the supported ionic liquid can be easily recovered and reused for six times with satisfactory catalytic activity. Furthermore, a general synergetic catalytic mechanism for the reaction was proposed. Maybe this work employing Ti-SBA-15@ILTsO as highly efficient and stable catalyst for the synthesis of 2,4,5-triaryl-1H-imidazoles has potential commercial applications.   Resumen. Se prepararon y probaron una serie de materiales mesoporosos soportados con líquidos iónicos como catalizadores eficaces y prácticos para la síntesis de 2,4,5-triaryl-1H-imidazoles. También se investigaron en detalle los efectos del tipo de catalizadores, la cantidad de catalizador y la estabilidad del catalizador. El catalizador Ti-SBA-15@ILTsO mostró una excelente actividad con rendimientos excelentes del 92 % ~ 99% con una baja cantidad de catalizador a temperatura ambiente en 1 h. Además, el líquido iónico soportado puede recuperarse fácilmente y reutilizarse durante seis veces con una actividad catalítica satisfactoria. Por otro lado, se propuso un mecanismo catalítico sinérgico general para la reacción. Este trabajo que emplea Ti-SBA-15@ILTsO como catalizador altamente eficiente y estable para la síntesis de 2,4,5-triaril-1H-imidazoles puede tener aplicaciones potencialmente comerciales.

Step Mechanism

Combustion of pulverized biomass in a laboratory swirl burner is computationally investigated. The two-phase flow is modelled by an Eulerian-Lagrangian approach. The particle size distribution and turbulent particle dispersion are considered. The radiative heat transfer is modelled by the P1 method. For modelling turbulence, different RANS modelling approaches are applied. The pyrolysis of the solid fuel is modelled by a single step mechanism. For the combustion of the volatiles a two-step reaction mechanism is applied. The gas-phase conversion rate is modelled by the Eddy Dissipation Model, combined with kinetics control. The results are compared with measurements.

Binary And Ternary Mixtures

The infrared spectra of chloral, carbon tetrachloride, and chloroform have been determined between 1500 and 650 cm.−1 over a range of pressures in the gas phase. Absorption bands suitable for the quantitative analysis of binary and ternary mixtures of the components have been selected and their peak intensities shown to obey Beer's Law over the range of pressures studied. Ternary mixtures have been analyzed from the spectra with an accuracy of about 20%.The spectra of dichloromethane and methyl chloride have also been measured under comparable conditions.
