Infrared Spectrometric Quantitative Analysis of Multicomponent Liquid Hydrocarbon Mixtures

Abstract

A method is described for making rapid accurate analyses of liquid hydrocarbon mixtures for all components. The method is a combination of distillation, infrared spectrometric, and calculation procedures. It has been applied to a wide variety of mixtures containing paraffin and isoparaffin hydrocarbons boiling between 28°and 124°C. Tests of Beer's law and optical density additivity are presented for several synthetic mixtures. The accuracy of the method is shown to be approximately 1% for each component.

Infrared Determination of Chlorinated Hydrocarbon Vapors in Air

“…The fact that the solutions being analyzed are very dilute is a contributing factor in this respect. However, when it is not possible to find peaks that are not affected by the presence of the other substances, the solutions must be analyzed in the manner usually used for mixtures (6,IS,28,32).…”

Qualitative Organic Analysis and Infrared Spectrometry

“…For the equilibrium between a crystalline phase consisting of the major component alone and a liquid phase consisting of the major component and one or more other components, the thermodynamic relation (see 11,20,21 for further details) between the temperature of equilibrium and the composition of the liquid phase, for an ideal or sufficiently dilute solution, is in V, = -in (1 -V2) = {MIfJRTh*) {th-t) X…”
