The limiting error of heat capacity calculated from these equations is 0.23% for benzene and 0.18% for hexafluorobenzene. From the data, equations for specific volume, thermal expansion coefficient, and the quantity (δT/δp)s were obtained for benzene and hexafluorobenzene....
Specific to hollow fiber configuration, there are three types of wetting patterns: non-wetting mode (where carrier liquid does not wet membrane pores), overall wetting mode, and partially wetting mode. The membrane supports used in liquid membranes are usually made of polymeric flat sheets in ...
Simultaneous measurements of heat capacities and densities of organic liquid mixtures. Systems containing ketones Flow techniques were used to determine the relative volumetric specific heat and the density on the same sample at 298.15K for each of the solvents: benzene, carbon tetrachloride, 2-butanone...
Supported ionic liquid membranes (SILMs) have been prepared by using imidazolium-based ionic liquids and hydrophobic polytetrafluoroethylene, and were deployed for the π electron-induced separation of aromatic compounds (toluene, styrene, divinylbenzene, congo red, eriochrome black T, and ramazol bril...
rather unusual results for the mixture xenon +ethane(Ref. 58); all the excess functions are negative. This type of behaviour is usually observedwhen there is some form of specific interaction between the molecules or association betweentwo hydrogen bonded compounds. The argument that the negative ...
error and to simply improve a measuring accuracy by attaching a bottom of a capacity rod with a scale having a smaller inner sectional area than that of a measuring container perpendicularly to a surface of a liquid, and calculating a capacity of the liquid according to the specific formula. ...
The specific shape parameters were obtained from the SEM images shown in Fig. 3. Second-order C3D8I elements were used during the simulations. In the analysis of the pyramid-shaped structure, initial geometric imperfections were introduced to the mesh to better trigger the torsional deformation ...
The sound speed in liquid methanol has been measured up to 280 MPa and in the temperature range between 203 K and 263 K, using a phase comparison pulse-echo technique operating at 2 MHz. The density, isothermal compressibility, isobaric thermal expansion and the specific heat have been evaluate...
A very modest heat effect (−41.7 kJ mol−1 for the R-I reaction) accompanies the hydrogenation of the double bond in a five-membered N-heterocycle. The hydrogenation of two double bonds in the benzene ring requires approximately the same energy per bond (−103.4 kJ mol−1 for the...
Figure 7.2.Model of double-layer structure of the solid–liquid interface with examples of specific and nonspecific ion adsorption [22] together with their hydration shell. Complete description of theelectrochemical propertiesof solids at the aqueous–solid interface, together with the origin of the su...
