摘要
Abstract
Effects of NaCl, KNO3, KCOOH, NaSCN and KSCN in dimethylformamide(DMF) as the solvent on the relative volatility of 1-pentene-isoprene system was measured.The salt-containing DMF could increase the relative volatilities of the 1-pentene-isoprene system, especially NaSCN-containing DMF with the suitable 4％ mass fraction NaSCN.The vapor-liquid equilibrium(VLE) data of isoprene-DMF + NaSCN, 1-pentene-DMF + NaSCN and cyclopentene-DMF + NaSCN were measured at 101.3 kPa, which were consistent with the thermodynamic consistency test.The obtained VLE data were correlated by NRTL equation and the model parameters were calculated.The maximal deviations of the vapor composition and the bubble point temperature were 0.87 ％ and 1.00 K, respectively.关键词
