POROUS SOLIDS, SELECTIVE SEPARATIONS, REMOVAL OF SULFUR COMPOUNDS, ADSORPTION

摘要

Crystals of [VOBDC](H₂BDC)_0.71 were synthesized hydrothemally. The guest acid molecules were removed by heating in air to give high quality single crystals of VOBDC. VOBDC was observed to show crystal-to-crystal transformations on absorption of the guest molecules aniline, thiophene and acetone from the liquid phase. Accurate structural data of the guest molecules and framework deformations were obtained from single crystal X-ray data. VOBDC was also shown to absorb selectively thiophene and dimethyl sulphide from methane.
