Vapor-liquid equilibriums of 1,3-butadiene systems

Abstract

was used without further purification, since it had a melting point of 2.5°± 0.1°C ., which was in good agreement with the literature value of 2.55°C. (5).A known excess of salt was added to a selected mixture of water and formamide in a 100-ml. volumetric flask. Each flask was attached to the arm of a mechanical shaker and immersed in a water bath which was maintained at 25°C.

Vapor-liquid equilibriums at 25.deg. in the binary mixtures formed by hexane, benzene, and ethanol

“…The ability of the analytical expressions for GE to fit the experimental pressure data, as shown in Table VI, substantiates results reported by others (5,14); the Wilson equation is the best of the two-parameter equations, often superior to higher order Redlich-Kister expressions.…”

Solubilities of gaseous butadiene and butene‐2 in possible extractive distillation solvents

“…Only the data of Wong and Eckert ( 1969) are available for comparison of butadiene solubilities in carbon disulfide and ethyl acetate. This comparison indicates our values are approximately 5%, and 0.1% lower in carbon disulfide.…”

“…The solubility of I -butene (Brooks and McKetta, 1955) and 1,3-butadiene (Reed and McKetta, 1959) in water were reported for various temperatures and pressures by McKetta and co-workers. The solubility of butadiene was also reported (Wong and Eckert, 1969) in seven solvents at 298.15 K and for a range of relatively low gas partial pressures. The latter data for two of the solvents provide a useful comparison for the results obtained in this work.…”
