The cell is set into a thermostat controlled water bath. With use of the binary interaction parameters determined from the data of the binary systems, the vapor pressure for the isobutane-n-butane-propane system can be estimated with the maximum deviation of about 0.02MPa. In general, K is a function of temperature, pressure, and composition.

Measurement of the (p,ρ,T) relation of propane, propylene, n-butane, and isobutane in the temperature range from (95 to 340) K at pressures up to 12 MPa using an accurate two-sinker densimeter. The estimated precision of the vapor pressure determination was better than 2kPa from the reproductivity of the data and the accuracies of the temperature, pressure, and composition measurements.The results of the isobutane-propane, n-butane-propane, and isobutane-n-butane-propane systems are summarized in Tables 1 to 3, respectively. This article is cited by 2).The vapor pressure was measured in accordance with the following procedure. the Altmetric Attention Score and how the score is calculated.

Vapor pressures of the three mixtures of light hydrocarbons, that is, isobutane-propane, n-butane-propane, and isobutane-n-butane-propane systems, were measured by a bubble point method in the temperature range from 273.15 to 323.15K. The chemical stability of phosphonium-based ionic liquids under gamma irradiation. For light hydrocarbon systems (methane to decane), the K values have been determined semi-emperically and can be evaluated from the equations given in Table 3.13. higher vapor pressure are called light components; lower vapor pressure are called heavy components ; Temperature and Vapor or Saturation Pressure for some common Fluids.
