Description
[0026]実施例1:
[0027]HFP、236ea、及びHFの標準沸点は、それぞれ−29.6、6.3、及び19.5℃である。それぞれ0.99、19.06、及び0.31gのHFP、236ea、及びHFを混合することによって、4.9重量%の236ea、93.6重量%のHFP、及び1.5重量%のHFの混合物を調製した。表1に示すように、混合物の圧力を0、25、及び60℃において測定した。次に、更なる量の高沸点(低圧)成分:HFを混合物に加えた。次に、0、25、及び60℃において圧力を再測定したところ、圧力の増加が示された。圧力の増加は共沸混合物の存在を示す。
[0030]実施例1におけるデータ並びにHF/HFP(米国特許6,407,297)及びHF/236ea(米国特許6,388,147)に関して得られるデータを用いて、表2に示すデータを算出した。表2におけるデータは、4.9gのHFP及び93.6gの236eaから出発し、徐々にHFを加えた。全圧は、最初は上昇するように見られ、次に約1重量%のHFを加えた後に横ばいになった。圧力は、その後は共沸混合物様の領域にわたって僅かしか変化しなかった。
[0032]実施例1における最終混合物(3.5重量%の236ea、88.1重量%のHFP、及び8.4重量%のHFを含んでいた)を、25℃に維持した浴中に配置した。蒸気試料を回収してHF濃度を測定したところ7.7重量%であった。これは、共沸点が約8重量%のHFを含むことを示す。
