Notes:
a
Reported (values given as percent (1) in original work).
b
Calculated by F. W. Getzen.
Method/Apparatus/Procedure:
A known amount of pure pentachlorophenol was added to cold water. Then, the temperature was raised slowly with agitation until dissolution was complete.
Source and Purity of Materials:
(1) Source and purity not specified.
(2) No specifications given.
Estimated Errors:
Solubility: <6% (estimated by the evaluator on the basis of the smoothed curve of log c vs. 1/T, where c denotes solubility).
