Ruoff, R. S.; Tse, D. S.; Malhotra, R.; Lorents, D. C.; J. Phys. Chem. 1993, 97, 3379-3383.

Variables:

Room Temp: 295 $\pu{K}$

Prepared by:

W.E. Acree, Jr.

Method/Apparatus/Procedure:

High performance liquid chromatograph system equipped with an ultraviolet detector and integrator. Excess solute and solvent placed in 1-dram glass bottle and allowed to equilibrate for 24 hours at ambient room temperature with agitation. Saturated solution was filtered through a 0.45 micrometer poly-(tetrafluoroethylene) filter. Concentrations determined via HPLC with uv detection at 340 nm. Stationary phase was a dinitroanilinopropyl column, and a binary toluene/hexane (20:80 by volume) mobile phase was used.

Source and Purity of Materials:

1. Graphite soot obtained by passing an ac discharge between spectroscopic grade graphite, and sample purified by chromatographic separation on alumina column. Final purity of 99.95% as determined by mass spectrometry.
2. Reagent grade, Baxter Scientific Products, McGaw Park, Illinois, USA, was used as received from manufacturer.

Estimated Errors:

Ambient temperature: T/K: ±3.
Mole fraction - Liquid (1): x₁: ±8% (relative error; compiler).
