Method/Apparatus/Procedure:
An improved apparatus for solvent pretreatment was used (Ref. 1). The gas content in the solution was analyzed with a gas burette. The solvent was equilibrated by flowing a liquid film through the gas. No supersaturation was observed.
Source and Purity of Materials:
(1) Prepare from marble.
The system was sealed to prevent contamination with air.
(2) Pure. Degassed.
Estimated Errors:
Temperature: Not stated.
