Abstract: An experimental apparatus was used to measure the solubility of ethyl nitrite in mixed
solvents under the lower pressure and higher temperature. The solubilities of ethyl nitrite
in mixed solvents of ethanol-water at 15℃-40℃ and ethanol-diethyl oxalate at 20℃-40℃
were determined. A Henry constant model has been improved, and the interaction parameters
have been fitted from experimental data. The calculation results have been compared with
experimental data; the results obtained are satisfactory.

Key words: solubility, ethyl nitrite, mixed solvents, Henry constant
