摘要:

AbstractBeer‐Lambert's law has a wide range of applications, spanning the fields of pure sciences and engineering, and is commonly used for the determination of the concentration of an optically sensitive compound, at “low” concentrations. In this report it is shown that a log‐log expression, log(T/T0) = K log(C/C0), accurately models experimental data (±3%) for four different absorbing species, at “high” concentrations. The dimensionless constant K is shown to be only a characteristic of the absorbing species, and independent of the spectrophotometer/cuvette system used. The new equation is used for on‐line monitoring of dynamic biomass concentration in a continuous bioreactor (CSTBR) for a step change in

摘要:

AbstractA newly developed laser light scattering technique was used for the determination of mutual solubilities in two liquid systems at moderate pressures. The solubility data and the upper critical solution temperatures are reported for the aniline + n‐hexane and furfural + cyclohexane systems. The experimentally determined cloud points were satisfactorily correlated by the NRTL equatio

摘要:

AbstractIsobaric vapor‐liquid equilibria (VLE) of methanol‐water and methanol‐ethanol systems with calcium chloride at several concentrations were studied from the view point of the applicability of Hála's model which had been applied to correlate isothermal VLE of salt‐containing systems. Prediction of the VLE of the two isobaric systems was not satisfactory with the binary interaction parameters taken from the corresponding isothermal systems because of the different temperature range. However, it was found that the correlation of the isobaric systems was successful by adjusting solvent‐salt parameters. It was also found that the parameters obtained were independent of the salt con
