Abstract
The formation of hydroquinone clathrates with CO 2, CH 4, N 2, and H 2 was investigated using X-ray diffraction, Raman spectroscopy, and solid-state 13C NMR spectroscopy. Of the hydroquinones prepared at 5.0 MPa, the CH 4- and CO 2-loaded hydroquinones show complete conversion to β-form hydroquinone clathrates while the N 2-loaded hydroquinone shows only partial conversion; there is no indication of the formation of hydroquinone clathrate with H 2. The CO 2-loaded hydroquinone is fully converted to the β-form hydroquinone clathrate even at 1.0 MPa. Solid-state 13C NMR measurements of the hydroquinone clathrate samples prepared at different pressures reveal that the conversion rate for the formation of clathrate compounds from CH 4 and N 2 decreases with decreasing pressure.
