  The alkylation of isobutane with butene is very important for the production of reformulated gasoline;however,the severe equipment corrosion and environmental hazards are involved in the current alkylation technology. Therefore,some novel alternative technologies are desired.

  异丁烷和烯烃烷基化反应对新配方清洁汽油的生产具有重要意义,而目前的烷基化工艺存在严重的设备腐蚀和污染问题,因此亟需新的替代工艺。

  And two vapor pressure equations were proposed for HFC-236fa and HFC-245fa based on the present measurements,respectively. Then the normal boiling points and Pitzer factors of HFC-227ea, HFC-236fa, HFC-245fa and isobutane, were determined.

  改进了实验台的压力测量系统、真空及配气系统,测量了HFC-143a、HFC-227ea、HFC-236fa、HFC-245fa、丙烷和异丁烷的饱和蒸气压;根据目前已有的实验数据和本文的测量结果分别提出HFC-143a、HFC-227ea、HFC-236fa、HFC-245fa和异丁烷的饱和蒸气压方程,确定了其正常沸点和偏心因子。
