Components:
   (1) Ethanol; C2H6O; [64-17-5]  NIST Chemistry WebBook for detail
   (2) Indole; C8H7N; [120-72-9]  NIST Chemistry WebBook for detail

Original Measurements:
   Yokoyama, C.; Ebina, T.; Takahashi, S., J. Chem. Eng. Data 1993, 38, 583-586.

Variables:
   Temperature = Ambient Room Temperature

Prepared By:
   W.E. Acree, Jr.

Experimental Data:   (Notes on the Nomenclature)
  

Mole Fraction x1	x1 Note	Mole Fraction x2	x2 Note
0.124	a	0.876	a

Notes:
   ^a  computed by compiler from published solvent compositions and solute solubilities, which were expressed as weight percent and grams of solute per 100 grams of solvent.

Method/Apparatus/Procedure:
   Excess solute and solvent equilibrated at ambient room temperature. Solution was filtered rapidly into a tared crucible. Solvent was evaporated. Solubility determined from weights of solid residue and evaporated solvent.

Source and Purity of Materials:
   (1) Purity and source not given, was used as received.
   (2) Absolute, chemical source not given, was dried over calcium carbide and distilled before use.

Estimated Errors:

   Temperature: T/K: Unknown. x₁: ± 8 % (relative error; compiler).
