Abstract

The contents of three forms of molybdenum oxide compounds in molybdena-alumina catalysts have been determined by their solubility in water and ammonia. The form which is readily soluble in water and reducible to Mo(IV) at 400°C and PH2=105 Pa is active in cyclohexane dehydration, and the forms soluble in water and ammonia are active in thiophene hydrogenolysis.

Abstract

По растворимости в воде и аммиаке определены количества трёх форм окисных соединений молибдена в алюмомолибденовых катализаторах. Активной в реакции дегидрирования циклогексана является легко растворимая в воде форма, восстанавливающаяся при 400°C и PH 2=I ата до Mo(IV); а в гидрогенолизе тиофена —растворимые в воде и аммиаке формы соединений молибдена.
