Adsorption isotherms and differential heats of adsorption of tetrahydropyrrol (THP) and cyclopentane CP), as well as THP and
methanol mixtures (mole ratio 1∶1, 1∶2 and 1∶4) on the graphitized carbon black Sterling MT surface were determined. The influence
of dilution of [THP] on its ability to undergo homomolecular association was tested. Even 1∶4 dilution of THP does not prevent
is association. Methanol strongly interacts with THP in the mixed adsorbed layer forming heteromolecular associates.
The thermal decomposition of FeS2 and BaO2 mixtures (mol ratio from 2 to 8) was studied in oxygen containing gas medium using dynamic heating rate. The solid decomposition
products have been investigated with X-ray power diffraction and Mssbauer spectrometer. The thermal process has two main
stages. In the presence of BaO2 the mixtures have a lower initial temperature of iron sulfide burning. The same time by the increasing of BaO2 content in the mixtures the diffusion difficulties are withdrawn in higher temperature ranges. It is proved that as intermediates
BaSO4, nonstoichiometric sulfide, barium ferrites and Fe2O3 are formed. The content of many solid phases in the final product is in relationship with the initial ratio of BaO2 and FeS2.

velocity of the ternary mixtures ethanol+water+1-propanol at the range 288.15–323.15
K and atmospheric pressure, has been measured over the whole concentration
range. The corresponding change of isentropic compressibility was computed
from the experimental data. The results were fitted by means of a temperature
dependent equation, such parameters being gathered. The obtained experimental
values indicate varying extent of interstitial accommodation among unlike
molecules as a function of steric hindrance attending to 1-propanol composition
as key component and as a function of hydrogen bond and temperature attending
to ethanol composition as key component.

In the chemical sciences, multi-component liquid mixtures are frequently encountered. In some cases, i.e., during complex chemical reactions, the individual constituents of the sample cannot be

Group contribution models have been introduced to predict thermodynamic properties of binary mixtures. Accurate calculations, at present, are not possible without the use of experimental data concerning at least a
process, which offers porosity of 65% and average pore size of 215 μm [ 13 ].
Recently, combustion synthesis conditions in the Ni + Zr + polytetrafluoroethylene (PTFE) mixture were studied to obtain porous (≈65%) NiZr-based materials with 50–600 μm
