| 摘 要： | 采用高功率1H去偶结合魔角旋转13C固体核磁共振技术,在低温常压条件下对合成的乙烷和丙烷气体水合物进行了测试,获得了两种纯气体水合物的13C核磁共振谱图,初步建立了固体核磁共振波谱法测定天然气水合物的实验方法.实验表明:乙烷水合物的13C核磁共振谱图中仅有一条谱线(δ7.7),结构类型为sI,且乙烷分子仅填充在大笼中(...

| Abstract: | Solid State NMR spectroscopy has taken a very prominent place in many spectroscopic techniques employed for the characterization of clathrate hydrates.In this work,we have measured the synthesized ethane gas hydrates by 13C NMR with Magic Angle Spinning(MAS) and High Power 1H Decoupling(HPDEC) at 173 K and atmospheric pressure.Furthermore,we have got the 13C NMR spectra of ethane gas hydrates and propane gas hydrates,and preliminary established the testing method of natural gas hydrate by Solid State 13C NM... |
