Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 20 (Octobre 2009) . - pp. 9335–9337 Titre : Characterization of the clathrate hydrate formed with methane and propan-1-ol Type de document : texte imprimé Auteurs : Keita Yasuda, Auteur ; Satoshi Takeya, Auteur ; Mami Sakashita, Auteur Année de publication : 2010 Article en page(s) : pp. 9335–9337 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Clathrate  hydrate  Methane  Propane-1-ol  X-ray  diffraction  Raman  spectroscopic  measurements Résumé : This paper reports the identification of the crystallographic structure of the clathrate hydrate formed in a system of methane + propan-1-ol + water. A hydrate crystal sample was prepared with a 0.0556 mole fraction aqueous solution of propan-1-ol pressurized with methane and then subjected to powder X-ray diffraction and Raman spectroscopic measurements. The X-ray diffraction pattern thus obtained from the sample indicated that the crystallographic structure of the hydrate was structure II. The Raman spectra thus obtained from the same sample indicated that the methane molecules occupied not only 512 cages but also 51264 cages.
