   Temperature = 278 K - 298 K

Prepared By:
   A. L. Horvath

Experimental Remarks:

   The Henry's law constant (H, dimensionless) was derived from a van't Hoff plot best-fit equation: loge H=13.04-3905/(T/K)

50.36821.002 x 10-11.354The Henry's law constant (H,dimensionless) was derived from a van't Hoff plot best-fit equation:
100.47189.92 x 10-21.341
150.59939.79 x 10-21.324
200.75529.66 x 10-21.305
250.94429.50 x 10-21.284
   The multiple equilibration technique was used to measure the Henry's law constant as described by McAuliffe.1 A known volume of pure 1,1,1-trichloroethane in a syringe was shaken with a known volume of pure water. After equilibration,  the headspace was separated and analyzed for the compound of interest. A gas chromatograph fitted with an electron capture detector was used for the analysis.

Source and Purity of Materials:
   (1) Source and purity not given.
   (2) Atlantic ocean samples, 48 °N to 65 °S latitudes, in late 1981.

Estimated Errors:
   Solubility: ± 5.5 % std. dev.
   Temperature: ± 0.2 K.
