摘要：

Catalytic activity of magnesium and zinc phosphates was investigated in butan-2-ol conversion, by proceeding during the reaction to selective poisonings by pyridine and acetic acid. The comparison of catalysts performances showed that the zinc phosphate exhibited basic sites stronger than those existing on magnesium phosphate. These sites are active in the alcohol dehydrogenation. Their strength seems to depend on the nature of the cations and the structure of the anhydrous phase.
