摘要：

The interaction of ethyne and ethyne-d2 with ZnNa-A zeolite yields results very different from those reported for related systems. Two adsorbed ethyne complexes are observed. One, a stable side-on π-bonded species is formed by coordination with the Na+ cations. The second has been identified as zinc acetylide (Zn-C≡C-H) and was observed to react slowly with zeolitic water to form ethanal. The rapid deuteration of hydroxyl groups and zeolitic water on adsorption of C2D2 was observed to be more efficient than exchange with D2O. Adsorption of ethyne by Ag-A zeolite was reinvestigated and it is shown that ethanal is formed over periods of prolonged contact. © 1990 American Chemical Society.
