Abstract

The volumetric behavior of an 81.739 mole % 1-butene mixture of propene and 1-butene was investigated at seven temperatures from 40°F to 280°F over a pressure range from about 40 pounds per square inch absolute to 10,000 pounds per square inch absolute. Tabulations of single-phase and two-phase data interpolated to even values of pressure are presented.

Revised volumetric data for three mixtures of propene and 1-butene previously investigated by Farrington are presented in tabular form over similar ranges of temperature and pressure. Variations of actual volumetric behavior from ideal behavior are shown graphically for the system.

The compositions of bubble-point liquid and dew-point gas were established experimentally throughout the two-phase region for temperatures between 40° and 280°F. Values of specific volume and composition for coexisting liquid and gas phases are tabulated. Equilibrium constants are given for propene and 1-butene. Properties for the critical region are estimated.
