Conditions:

Room Temp: 303 $\pu{K}$

Compiler:

W.E. Acree, Jr.

Methodology:

Constant temperature bath, stirrer, thermometer, and an ultraviolet/visible spectrophotometer. Excess solute and solvent placed in glass tube and allowed to equilibrate for 5 hours at constant temperature with stirring. Tube was then centrifuged and aliquots of saturated solution was with- drawn and the absorbance measured at 328 nm after appropriate dilution with spectroscopic grade n-hexane.

Sample Information:

1. Graphite soot obtained by passing an ac discharge between spectroscopic grade graphite, fullerness recovered by soxhlet extraction with toluene, and sample purified by chromatographic separation on alumina column.
2. HPLC grade or AR grade solvent, chemical source not given, aromatic impurities removed by chromatography if necessary.

Measurement Errors:

Ambient temperature: T/K: ±0.1.
Mass concentration (m/v) (1): c₁: ±3% (relative error; compiler).
