Method/Apparatus/Procedure:
The titration method was used. A 100 mL glass flask and a microburette with scale divisions of 0.01 mL were used. The solution was mixed by a magnetic stirrer. The titration was continued until the second phase appeared. The amount of added substance was obtained by weighing the mixture before and after the titration.
Source and Purity of Materials:
- Source not specified; pure grade reagent; dried over CaCl2 and repeatedly distilled in a laboratory packed column of 20 theoretical plates; b. p. = 101.20°C, n(20°C, D) = 1.3820.
- Source not specified; CP reagent; distilled; b. p. = 98.42°C, n(20°C, D) = 1.3877.
