Method/Apparatus/Procedure:
   The experimental apparatus and analytical technique are described in ref 1. The equilibrium apparatus consisted of a jacketed cell with an internal heating coil. The mixing of the contents of the cell was achieved by a rocking mechanism.

Source and Purity of Materials:
   (1) Phillips Petroleum Co., purity 99.0 mole percent; used as received.
   (2) distilled and boiled to remove any dissolved gases.

Estimated Errors:

   Temperature: not specified.
