Abstract

Brillouin scattering technique has been used to measure the pressure dependence of sound velocity v/sub s/(P) in model oil samples (each containing 5-hydrocarbon liquids) at room temperature T = 20/sub 1/ /sup 0/C. Experimental results are reported on two blends of model oil, each containing a mixture of n-heptane, n-tetradecane, cyclo-hexane, benzene, and toluene in different volume fractions. The compositions of these two differed in their cyclohexane and toluene contents. The pressure dependence of v/sub s/(P) has been measured up to 815 bars and the results could be least-square fitted to v/sub s/(P) = A/sub 0/+A/sub 1/P+A/sub 2/P/sup 2/ within the limits of experimental error ( +- 1%). The modified Tait's equation and linear pressure dependence of bulk modulii have been used in consistence with an earlier work to interpret the parabolic pressure dependence of v/sub s/(P). This yields the values of Tait parameters (B and C) and hence allows the explicit pressure dependence of density and compressibility of these multicomponent liquids to be evaluated.

Adsorption of multicomponent liquid mixtures on heterogeneous surfaces. Analysis of experimental data, measured at constant ratios of mole fractions of components in the bulk phase

Journal Article Borowko, M; Oscik, J; Jaroniec, M; ... - J. Colloid Interface Sci.; (United States)

The equations were developed to describe adsorption from multicomponent ideal liquid systems on homogeneous or heterogeneous solid surfaces yielded predictions of the adsorbed-surface-phase composition that agreed satisfactorily with experimental data for the n-heptane/cyclohexane/benzene, n-heptane/cyclohexane/toluene, and n-heptane/cyclohexane/p-xylene ternaries on silica gel at 20/sup 0/C.
Diluent and extractant effects on the enthalpy of extraction of uranium(VI) and americium(III) nitrates by trialkyl phosphates

Journal Article Srinivasan, T; Vasudeva Rao, P; Sood, D - Solvent Extraction and Ion Exchange

The effect of various diluents such as n-hexane, n-heptane n-octane, isooctane, n-decane, n-undecane, n-dodecane, n-tetradecane, n-hexadecane, cyclohexane, benzene, toluene, p-xylene, mesitylene and o-dichlorobenzene on the enthalpy of extraction of uranyl nitrate by tri-n-amyl phosphate (TAP) over the temperature range 283 K--333 K has been studied. The results indicate that the enthalpy of extraction does not vary significantly with the diluents studied. Also enthalpies of extraction of uranyl nitrate and americium(III) nitrate by neutral organo phosphorous extractants such as tri-n-butyl phosphate (TBP), tri-n-amyl phosphate (TAP), tri-sec-butyl phosphate (TsBP), tri-isoamyl phosphate (TiAP) and tri-n-hexyl phosphate (THP) have been studied.

Degradation of jet fuel hydrocarbons by aquatic microbial communities. Interim report 23 October 1981-30 September 1983

Technical Report Spain, J; Somerville, C; Butler, L; ...

A model fuel mixture of fifteen hydrocarbons representative of those in distillate jet fuels was used to determine whether degradation by natural microbial communities could affect the persistence of such fuels released into aquatic environments. The mixture included hexane, cyclohexane, n-heptane, methylcyclohexane, toluene, n-octane, ethylcyclohexane, p-xylene, cumene, 1,3,5-trimethylbenzene, indan, naphthalene, 2-methylnaphthalene, n-tetradecane, and 2,3-dimethylnaphthalene. The water-soluble fraction of the model fuel was incubated in shake flasks with water or water and sediment suspensions collected at estuarine and freshwater sites. Surface films of the model mixture were studied under quiescent incubation. The disappearance of hydrocarbons was measured by capillary gas chromatography.more »« less
Pressure dependence of the density of n-alkanes

Journal Article Susnar, S; Budziak, C; Neumann, A; ... - International Journal of Thermophysics; (United States)

Accurate density data for n-alkanes are essential for the measurement of interfacial tension of liquid-liquid systems as a function of pressure. The variation of density with pressure for three n-alkanes, n-hexane, n-heptane, and n-decane, was measured at 21.2[degrees]C and pressures ranging from 0.1 to 35 MPa with a digital density meter. The Tait equation of the form ([rho] [minus] [rho][sub 0])/[rho] = C log[(B + P)/(B + P[sub 0])] was used to represent the experimental data. 20 refs., 2 figs., 4 tabs.

Shock compression data for liquids. I. Six hydrocarbon compounds

Journal Article Dick, R - J. Chem. Phys.; (United States)

Dynamic high pressure equation-of-state data are reported for 1,3- and 1,4-cyclohexadiene, cyclohexene, cyclohexane, toluene, and n-hexane initially in the liquid state. Plane shock waves generated by high explosives produced pressures of 0.5 to 43.0 GPa and densities to twice normal density. Toluene and n-hexane exhibit transformations at 12.6 and 19.0 GPa, respectively, but cyclohexadiene, cyclohexene, and cyclohexane do not. Decomposition of the molecule is the probable cause for the transition. Results indicate that reducing the number of double bonds by adding hydrogen pairs to the benzene molecule causes the transition to disappear.
