nitrile with the molecular formula C2H5CN. It is a clear liquid with an etherial, sweet odor.Propionitrile can be produced by the dehydration of
propionamide , by reduction ofacrylonitrile , or by distillingethyl sulfate andpotassium cyanide .Propionitrile is poisonous when heated to decomposition, or by treatment with acids.
To calculate the vapor pressure (P) at a given temperature K (in Kelvin), where that temperature falls within the range of -35 to 97.1 degrees Celsuis, use the following equation:
Log P = [(-0.2185)(8769.0) /K ] + 8.079473
