“…Specific gravities were determined pycnometrically under thermostatically controlled conditions at 25°C (Ellis and Mills, 1953). Mean molecular weights were determined by the freezing point depression method (Rail and Smith, 1936). Furfural miscibility temperatures were obtained by the method of Rice and Lieber (1944).…”

No systematic studies have been reported correlating t h e physical properties of brominated kerosene with t h e degree of bromination. T h e present paper represents such a study for a kerosene fraction boiling between 180 and 220°C obtained from a Kuwait oil field and having a low aromatic content (high furfural miscibility temperature). This kerosene was brominated from 6.5 to 36% bromine content in steps of approximately 0.2 mol of bromine. T h e products have been checked for purity by gas chromatography and characterized by their ir, uv, and nmr spectra. T h e measurements comprise elementary analysis, refractive index, surface tension, furfural point, kinematic viscosity, specific gravity, and molecular weight. These data are correlated with t h e degree of bromination and t h e average molecular composition obtained.

“…

T HE MOLECULAR weights of high boiling fluids are often determined by freezing point depression or boiling point elevation. Previous investigations (8,9) have shown that these apparent weights usually depend on concentration. When accurate values are desired, freezing point depressions must be determined at several concentrations and the data extrapolated to infinite dilution to eliminate solute-solvent interaction effects.

“…0 A 5% correction was applied to experimental molecular weights for reasons given in text. In regard to the cryoseopic technique, the previous recommendations (14,26) that the freezing point depression be deterworkers (21, 22, 23) were given greatest weight in deriving the correlations presented in this paper.…”
