Equilibrium content

This condition applies when the equilibrium content of the slag of the impurity being transfeiTed would be high, but the bulk of the slag is large compared to the volume of the descending metal particle. When is not much less than... 

The tautomeric equilibria of 5-hydroxy-3-aminopyrazoles 226 are affected by the substituent R" (Scheme 77) [76AHC(S1), p. 467]. While structure 226b is usually the major form, for some compounds of type 226 (R = COMe, COPh) the equilibrium content of 226c may reach 60% (74BSF291). 

CDCI3, DMSO-d, pyridine-ds), the equilibrium content of the ring-opened form 273 increases with increase in solvent polarity and electron-donor ability of the aryl substituent R. In the sohd, the cyclic tautomers are preferred as proven by IR spectroscopy (97ZOR418).

Phenoxatellurin, in addition to the other phenoxachalcogens, forms a crystalline complex, as donor, with 7,7,8,8-tetracyano-pflrfl-quinodimethane (TCNQ) whose stoichiometry was found to be 1 1. The equilibrium content and the activation coefficients are relatively small, suggesting that the complex formed in dicloromethane solution is relatively weak, probably due to the n-n charge transfer type. 

Results. In a typical experiment on the explosion of a mixture of 23.5% CO with air at p0 = 5 kg/cm2 we obtained 0.33% NO. The computed explosion temperature Tm = 2560°K and [NO] = 0.99%. However, experimentally we observed a maximum pressure of 2.5 kg/cm2 which corresponds to an explosion temperature T = 1670°K the equilibrium content of nitric oxide at 1670°K equals [NO] = 0.11%. It might appear that a triple yield of nitric oxide compared to the equilibrium value at the measured temperature even in one experiment would prove the existence of a non-thermal mechanism regardless of any other findings. Hausser [8] drew just such a conclusion from similar data. However, as we shall see later, it is incorrect. 

The equilibrium ratio polymer/monomer is the same in the base catalysed polymerization as in the hydrolytic process (43, 94) and so is the equilibrium content of cyclic oligomers in both processes (43). Using the extremely fast basic polymerization it was made possible to follow the equilibrium in the range of very low temperatures, where it was hardly possible before. It was found that in polymers which were prepared below their melting point, the monomer content is essentially lower than would be expected from the extrapolation of the temperature depend-ence of the equilibrium monomer content obtained at higher temperatures (94) (fig. 5). This indicates that the crystaline fraction of the polymer does not participate in the equilibrium. It is possible to establish the concentration of the amorphous part independently, e. g.

Since in good hydrogen bond accepting solvents such as DMSO, the equilibrium content of ends of 2-arylpropionaldehydes is relatively high (up to 50%) [187], their oxidation potentials were readily determined by cyclic voltammetry in at tonitrile/DMSO mixtures [171], A closer analysis, however, indicated that actually enol DMSO complexes were measured exhibiting some enolate character, since the oxidation potentials found proved to be significantly lower than the ones calculated by the above procedure.

In the investigation of properties of the Ca0-Fex03,-Si02 melts in air, it is necessary to know the equilibrium composition of the melt as the function of the temperature and total melt composition. Larson and Chipman (1953) and Timucin and Morris (1970) studied the phase diagram of this system, where the equilibrium contents of di- and trivalent iron in the melt were determined in quenched samples. The presence of ions of the same kind in two oxidation states results in an increased electrical conductivity of the melt due to the contribution of the electronic conductivity caused by the electrons jumping between the two ions in different oxidation states.

This result permits the conclusion that on oxides with equilibrium content of oxygen, the simplest catalytic reaction, such as the isotopic exchange in molecular oxygen, proceeds with the participation of oxide oxygen. On oxides with uniform surface all surface oxygen participates... 

From these two reactions it can be gathered that at higher temperatures less CH4 and more CO will be present in the equilibrium gas. However, by LeChatelier principle, increasing the pressure will increase the methane equilibrium content. Reaction 2.3 represents the steam reforming of higher hydrocarbons, which are present in small quantities in natural gas.
