【摘要】 裂解的C₅馏分中有大量间戊二烯,若将其分出,须测定其与主要杂质环戊烯的汽液平衡数据。现用鼓泡平衡釜测以下体系等温汽液平衡值。（1）反戊二烯_-1.3～环戊烯;（2）反戊二烯_-1.3～环戊烯～乙腈;（3）反戊二烯_-1.3～环戊烯～N—甲基吡咯烷酮（NMP）;（4）反戊二烯_-1.3～环戊烯～N,N—二甲基甲酰胺（DMF）.三元体系反戊二烯_-1.3（1）～环戊烯（2）～溶剂（3）（乙腈、NMP、DMF）无限烯释下相对挥发度α₁₂,活度系数γ₁₂^∞亦用色谱法测得其结果与平衡釜相符。更多还原

【Abstract】 There exists a rich piperylene content in cracking C₅ fractions. In order to separate from C₅ fractions, it is necessary to determine the vapor liquid equilibrium relations for systems containing piperylene and cyclopentene（the main inpurity in piperylene）This paper provides the vapor-liquid equilibrium data of the following systems which were obtained by use of a modified Junghan’s still at constant temperatures.（1） t-Pentadiene-1,3--Cyclopentene;（2） t-Pentadiene-1,3--Cyclopentene--Acetonitrile;（3） t-Pentadiene-1,3--Cyclopentene--N-Methyl Pyrrolidone（NMP）;（4） t-Pentadiene-1,3--Cyclopentene--N,N-Dimethyl Foramide （DMF）;The relative volatilities a^∞₁₂ and activity coefficients γ^∞₁₂ at infinite dilution for systems t-pentadiene-l,3（1）--cyclopentene（ 2 ）--solvents（3） （acetonitrile,NMP, DMF） are also determined by using chromatographic method. The values obtained coincide well with those determined by using Junghan’s still.更多还原
