Rapid Determination of Aromatics in Petroleum Fractions

Correlation of the mutual solubilities of two liquids with the electric and magnetic properties of the pure components

“…At present, the relation between mutual solubilities and the physico-chemical properties of the pure components is not known.4 This is the purpose of the present paper, which started when studying the fundamental basis of an analytical method. 5 Eqn. (1) is evident when, for any system having two liquid phases and two components, the experimental data are tabulated as in table 1 (for the system water+methylethylketone as an example).…”

Review - Petroleum

“…Bomstein (14) determined total aromatics in naphthas by measuring the area under the infrared spectrogram from 5.00 to 5.85 microns; he claims advantages over acid absorption, ultraviolet absorption, and Raman and mass spectrometry. Pasquinelli (141) determined aromatics in a w'ide variety of petroleum fractions boiling below 600°F. by the reduction in hydrocarbon volume that occurs when the sample is shaken for 2 minutes with a 22% solution of anhydrous picric acid in nitrobenzene.…”
