Molybdenum trioxide CAS#1313-27-5

Basic Information

Molybdenum trioxide
VI

Molybdenum trioxide is an odorless white crystalline powder that turns yellow when heated. It is slightly soluble in water, thermally stable and relatively unreactive under ordinary conditions, making it suitable as a controlled molybdenum source. It is used in catalyst formulations for petroleum-feedstock desulfurization and nitrogen-compound removal. It also serves as a reagent in chemical analysis and as a starting material for preparing molybdate salts.
