摘要：

The irreversible adsorption of boron trifluoride on calcined gamma-alumina and amorphous chromia, in both cases at room temperature, has been studied using [F-18]-labelled BF3. Although the resulting gamma-alumina surface has some catalytic activity for the room temperature fluorination by anhydrous HF of CH3CCl3 under static conditions, its activity is far lower than that of gamma-alumina, which has been fluorinated with SF4, nominally at room temperature. A possible explanation for the observed behaviour is given. (c) 2006 Elsevier B.V. All rights reserved.
