【摘要】 本文报道Pd/Al₂O₃（1%）催化剂催化氢化CF₃CCl=CClCF₃,CF₃CCI==CHCF₃和CF₃C=CCF₃等多氟烯烃和炔烃的结果。经1^H和（19）^F核磁共振、质谱、红外等分析,证明了用制备色谱分离后的氢化产物主要成份的结构。前二者的氢化产物中主要是CF₃CH₂CH₂CF₃和CF₃CH₂CHClCF₃的混合物,而CF₃C=CCF₃氢化后只生成CF₃CH₂CH₂CF₃。更多还原

【Abstract】 This paper deals with the catalytic hydrogenation of CF₃CC1=CC1CF₃,CF₃CC1=CHCF₃ and CF₃C=CCF₃by Pd/Al₂O₃.The hydrogenated products separated bypreparative gas chromatography were identified by MS,IR and NMR.It was found thatthe first two compounds gave a mixture of CF₃CH₂CH₂CF₃ and CF₃CH₂CHC1CF₃,whilethe last compound gave CF₃CH₂CH₂CF₃.更多还原
