An effusion-mass spectrometric investigation of the Be–Cl–F system to obtain bond energies of BeF and BeCl and the heat of formation of the mixed halide BeClF has been completed. A study of the ion intensities of the species ...

A fast and efficient mass spectrometric—Knudsen effusion method for the determination of heats of sublimation of organic compounds is introduced. The heats of sublimation of a number of organic compounds have been determined ...

The dissolution rate of commercial superphosphate fertiliser was studied at 25, 35 and 45°C using a rotating disc of the solid material. The kinetics were followed by means of a calcium ion-selective electrode and ...

Excess volumes have been measured dilatometrically for binary mixtures of six n-alkancs (n- pentane, n-hexane, n-heptane, n-octane, n-dccane and n-tetradecanc) with four linear dimethylsiloxanes (dimer, trimer, tetramer ...

Gas–liquid critical temperatures Tcm have been determined for four mixtures: (i) n-hexane + hexamethyldisiloxane, (ii) n-octane + hexamethyldisiloxane, (iii) n-octane + octamethyltrisiloxane, and (iv) n-octane + ...

The binary diffusion coefficient of HCl in H2 may be represented by 0.54(T/273 K)1.85 cm2 S–1 over the temperature range 700–1300 K. We present a useful second-order approximation to multicomponent diffusion, which permits ...

A method of evaluating vapour pressures and equilibrium constants for heterogeneous reactions is proposed. It replaces the usually indeterminate contribution of gaseous transport in the conventional entrainment method by ...

The kinetics of rapid bimolecular reactions involving ClO, X2Π, v= 0, radicals at 298 K have been studied mass spectrometrically using molecular beam sampling from a discharge-flow system. The following rate constants (298 ...

At 25°C the formation constant of MnCl2+ is found by spectrophotometry to be 13.2 ± 0.9 dm3 mol–1 at ionic strength 3.26 mol dm–3; for MnCl+2 the value is 1.1 ± 0.7 dm3 mol–1. Increase in the number of chloride ions in ...

Equilibria involving gaseous species CuLi, AgLi and AuLi have been investigated using a Knudsen effusion technique combined with mass spectrometric analysis of the vapour composition. The following dissociation energies ...
