Conditions:
Room Temp: 20 °C
Compilers:
Z. Maczynska, A. Maczynski, A. Szafranski
Methodology:
In a serum cap-sealed 4-oz. Brown glass bottle immersed in a water bath, (1) was saturated with (2) at 20 ± 0.02 °C for seven days. A 20-mL sample was withdrawn with a silicone-hydrophobized hypodermic syringe pushed about 2/3 of the way into the hydrocarbon liquid. Stabilized Karl Fischer reagent diluted to a titer of 1.0-1.3 mg(2)/mL was used to titrate (2) in (1) directly in the presence of methanol to a dead-stop end-point using a Beckman KF3 automatic titrimeter with a 5-mL miroburet.
Sample Information:
- Matheson, Coleman and Bell Chromatoquality reagent 99+ mole%; used as received.
- Distilled and deionized.
Measurement Errors:
Ambient temperature: ±0.02 K
Mass concentration (m/v) (1): ±3 mg(2)/kg(1) (type of error not specified).
System Components:
- Benzene, $\ce{ C6H6 }$; [71-43-2] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of water in benzene at 20°C was reported to be 532 mg(2)/kg(1).
The corresponding mass percent and mole fraction calculated by the compilers are 0.0532 g(2)/100 g sln and 2.30 × 10-3.
