Conditions:
Room Temp: 0.4 - 42.8 °C
Compiler:
Methodology:
A round-bottomed flask containing about 4 mL of (1) and 400 mL of (2) was evacuated, suspended in a thermostat, shaken for 24h and then allowed to settle for at least another 24h. Next, desired quantities of the water layer were syphoned into 6 glass-stoppered Erlenmeyer flasks. These 6 flasks had previously been tared, partialy filled with a suitable amount of diluent water, and reweighed. Weighed portions of the samples were inserted into a quartz cuvette and measured in a Beckman DU spectrophotometer. Absorbances were corrected for absorption of (1) onto the walls of the cuvette.
Sample Information:
- Matheson Co., purified by recrystallization from absolute methanol.
- Air-free conductivity water, no further details given.
Measurement Errors:
Ambient temperature: ±0.02°C
Mass concentration (m/v) (1): ±0.5% relative
System Components:
- Biphenyl, $\ce{ C12H10 }$; [92-52-4] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
Solubilities of (1) in (2) were reported as "optical density" (absorbance) measurements. Solubilities were calculated by the compiler using the Beer-Lambert law, the stated cell path-length (1 cm) and the authors' "extinction coefficients" (absorptivities) and corrected optical densities. This gave a solubility of g(1)/L sln which was then converted to g(1)/100g sln by assuming a solution density of 1.00 kg/L.
