Hydrogenation Selectivity

Hydrogenation of olefinic substrates in binary and ternary mixtures using 5% Pt on silica gel as the catalyst was studied in normal conditions in the liquid phase with methanol or cyclohexane or in solvent-free systems. The effect of the solvent concentration on the selectivity of hydrogenation of the unsaturated alcohol-olefin binary mixtures was investigated. In ternary systems of unsaturated substrates, the effect of each of the substrates on the selectivity of hydrogenation of the remaining two substances was examined. Another system was found in which a jump change of the hydrogenation selectivity occurred on the vanishing of the fastest reacting substance.

Dipolar Aprotic Solvents

Solvation of Li+, Be2+, Na+, Mg2+, and Al3+ ions has been studied in binary mixtures with dimethyl sulphoxide, dimethylformamide, acetonitrile and water, and in ternary mixtures of the organic solvents with water. The CNDO/2 quantum chemical method was used to calculate the energies of solvation, molecular structures and charge distributions for the complexes acetonitrile...ion (1:1, 2:1, 4:1), dimethyl sulphoxide...ion (1:1), dimethylformamide...ion (1:1), and acetonitrile (dimethyl sulphoxide, dimethylformamide)...ion...water (1:1:1).

Enthalpies Of Mixing

Enthalpies of mixing are reported for ternary n-alkane mixtures prepared from binary mixtures with large chain-length differences and at temperatures where the enthalpies of mixing of simple binary mixtures show changes of sign. In neither case does the behaviour of the ternary mixtures deviate significantly from that of the congruent binaries.

Binary And Ternary Mixtures

The capacity of humans to identify the components of taste mixtures and odour – taste mixtures was investigated in two experiments. Subjects were trained to identify the components presented alone and to use a ‘yes/no’ procedure to identify them in mixtures. All stimuli were presented with a retronasal (by mouth) technique. A maximum of three tastants were identified in both types of mixtures, only one tastant was identified in five-component taste mixtures, and no component was identified in four-component odour – taste mixtures. Importantly, in no instance was the olfactory stimulus identified in any mixture with tastes, including binary mixtures. Loss of identity of the odorant in binary and ternary mixtures may have been due to suppression as a consequence of temporal processing, or to the absence of an association between the odorant and tastants that had established an identifiable percept. In contrast, poor identification of the components of the quaternary odour – taste mixture and quinternary taste mixture is attributed to the limited capacity of working memory. Overall, the poorer ability to identify components in odour–taste mixtures than in taste mixtures indicates that interactions occurred between the two senses, challenging the proposal that odours and tastes are processed independently when present in complex chemosensory stimuli.

Detonation limits have been studied for binary mixtures of tetramethylsilane ( TMS ) with oxygen and also for ternary mixtures including up to 92% of helium by volume. The limits for the binary system are 1⋅8% and 48 to 50% TMS by volume. The object of these researches was to study factors controlling transition from detonation to deflagration, particularly when a time lag is introduced in the liberation of chemical energy by the need to condense and crystallize or to polymerize non-volatile reaction products before the large heat changes involved can contribute to the propagation of detonation. Solids formed in the detonating mixtures were examined to determine their composition, density, structure, surface area and electrical conductivity. As the composition of the mixture is progressively changed, a systematic trend is observed in properties of the solid products. This appears to correspond with different modes of propagation of detonation. Starting with the oxygen rich limit where carbon-free silica is formed, the solids change colour rapidly from white to black in a transition region between 28 and 32% by volume of TMS , remaining black for richer mixtures. Black solids incorporate appreciable proportions of carbon. Two peaks in ‘detonation strength’ characterize different regions, in which the trends of fluctuations in the velocity of propagation of detonation correspond with changes in the solid products. Calculations make it clear that the heat of formation of various solids contributes towards the hydrodynamic propagation of the detonation wave. However, the condensation of silica appears to act in a manner different from the formation of carbon. Extremely dilute mixtures of TMS will still detonate. For binary mixtures, the lower limit is found at 1⋅8% TMS by volume. For ternary mixtures, detonation is still found with 0⋅9% TMS , 7⋅8% oxygen and 91⋅2% helium. Some implications of this finding are discussed.

Binary And Ternary Mixtures

Kinematic viscosities of acetone, vinyl acetate, crotonaldehyde, acetic acid, acetic anhydride, their binary mixtures and two ternary mixtures (acetone-vinyl acetate-acetic acid and vinyl acetate-acetic acid-acetic anhydride) were measured. The values of coefficients of the Linke, McAllister, and Chandramouli-Laddha equations were calculated. The temperature dependence of the coefficients of last two equations can be expressed in terms of a function in exponential form, coefficients of which are tabulated.
