Methodology:
The method consisted of preparing serial dilutions of a suspension of [1] in [2] and determining nephelometrically the amount of [1] per unit volume beyond which further dilution caused no reduction in light scattering, which remained equal to that of pure [2]. A Bausch and Lomb Dubosque colorimeter model 100-mm was employed. Many details are reported in [1].
Sample Information:
- Prepared at Harvard University; MP = 216.6-217.3°C (cf. [2]).
- Dust-free.
Measurement Errors:
Ambient temperature: ±3°C
Mass concentration (m/v) (1): See above

Experimental Data
The best value recommended by the authors is 8 × 10-7 g(1) L-1 (2). With the assumption that 1.00 L sln = 1.00 kg sln, the corresponding mass percent and mole fraction, x1, calculated by the compiler are 8 × 10-8 g(1)/100 g sln and 6 × 10-11.
