Method/Apparatus/Procedure:
Experimental procedure only marginally described by author. Excess solute and solvent were equilibrated in a constant temperature water bath for between 10-30 minutes. Saturated solution was withdrawn through a coarse filter and analyzed by specific gravity. Author noted that evaporation to dryness and weighing the residue was subject to too much decomposition.
Source and Purity of Materials:
(1) Purity not given, Kahlbaum, was recrystallized from alcohol to a melting point temperature of 93.5 °C.
(2) Marked absolute, from Eimer and Amend and Chas. Cooper and Co., dried over calcium oxide and distilled before use.
