Methodology:
The analytical method was used. Mixtures of known overall compositions, by weight, were stirred intensely and allowed to settle for 2 h at constant temperature bath. Samples of each phase were taken and analyzed by GLC method with 1-propanol as internal standard. (1-propanol also prevented phase separation). Analytical conditions: column 2 m x 3 mm, packed with Chromosorb 101 100/120, temp. 190 °C, thermal conductivity detector for the organic phase, flame ionization detector for aqueous phase, helium flow rate - 40 mL/min. Decahydronaphthalene was reported to be undetectable in the organic phase.
Sample Information:
- Merck, used as received; <0.2 wt% impurities by GLC.
- Merck, used as received; mixture of cis-and trans-isomers.
- Source not reported.
Measurement Errors:
Ambient temperature: Temp. ±0.1°C.
Mass concentration (m/v) (1): Not reported.
