Clathrate hydrate is a sort of ice materials which can capture a large amount of gas molecules (~170 vol/vol) in hydrogen-bonded water framework. Particularly, ionic clathrate hydrates are able to contain hydrophobic cationic or anionic guests in counterion-incorporated clathrate framework. For instance, diethyldimethylammonium hydroxide (Et2Me2NOH) hydrate is a known ionic clathrate hydrate that Et2Me2N+ is enclathrated in a hydroxide-doped water framework and that can form structure H (sH) binary hydrate with the secondary gaseous molecules such as CH4. In this work, binary clathrate hydrates of diethyldimethylammonium fluoride with CH4 were synthesized and their crystal structures were identified by using powder X-ray diffraction pattern analysis. The phase equilibria of synthesized samples were also investigated to check the effects of anions incorporated in the framework on the thermodynamics of ionic clathrate hydrates. |
