Mutual solubility of acetonitrile (1) and methylcyclohexane (2)

t/°C	T/K	102 * Mass Fraction w1 (compiler)	Mole Fraction x1	Comment(s)
25.00	298.15	2.36	0.0546	Hydrocarbon-rich phase
25.00	298.15	87.70	0.9446	Acetonitrile-rich phase

Method/Apparatus/Procedure:
   The analytical method was used. Liquid-liquid equilibrium measurement was performed by use of a thermostated equilibrium cell containing about 70 mL of mixture in the absence of a vapor phase. A two-phase mixture in the cell was vigorously mixed by use of a magnetic stirrer for 2 H and allowed to settle for 2 h at 298.15 K so as to ensure phase separation. After equilibrium was established, samples of two layers were withdrawn with precision Hamilton syringes and their compositions were determined by use of gas chromatograph with an electronic integrator.
