Ecological Application of Carbon Dioxide and Its Use in Sustainable Chemistry
Bušta, K. ; Wagner, Zdeněk
Carbon dioxide, which is mostly waste of chemical processes and of combustion processes, finds currently a wide scope of application as a versatile technical gas, as one of basic building blocks for synthesis in organic chemistry. A great many applications in the technical area contribute to the protection of the environment and human health. Zadejte text nebo adresu webu nebo přeložte dokument. Zrušit Poslech Překlad (česky > anglicky) These applications include the use of carbon dioxide as an extraction agent to obtain aromatic and medicinal substances from natural materials in the food and pharmaceutical industries.

Pokroky v popisu termodynamických vlastností soustav obsahujících alkanoly
Aim, Karel ; Nezbeda, Ivo
Two lines of research dealing with the applications of the so called primitive models (of association) to describe the thermodynamic properties of alkanolic systems will be outlined, namely (i) molecular simulations for the water and methanol mixtures, and (ii) equation of state developments for the alkanol and carbon dioxide systems. Molecular simulations on water–methanol mixtures were performed by using primitive models that descend from realistic models of molecular interaction for both compounds. The results for both the excess mixing and partial molar properties of the system over the entire concentration range were compared with the molecular simulation results for the commonly accepted complex realistic models (effective pair-wise potentials) and with experimental data.

Měření a predikce pevné sloučeniny v systémech s iontovou kapalinou
Sedláková, Zuzana ; Sauton, H. ; Malijevská, I. ; Hynek, V.
In present time there is an increasing focus on ionic liquids. Solid-liquid equilibrium has been measured for ternary cuts in two organic systems. Systems were contained of carboxylic acid (acetic acid or propanoic acid) plus formamide plus ionic liquid 1-butyl-3-metylimidazolium chloride. Dissociation thermodynamics quantities were calculated for solid compounds from binary systems. Obtained estimation of the range of solid compounds was compared with experimental data.
