Properties and uses of sodium molybdate
Sodium molybdate is sodium molybdate, chemical formula Na2MoO4, which is a white rhombic crystal. It can be used in chemical reagents, dyes, pigments and other fields.
physical properties
Sodium molybdate is soluble in water but insoluble in acetone.
chemical properties
Sodium molybdate reacts with acid to produce molybdic acid precipitation:
Na2MoO4 + 2 HCl → H2MoO4↓ + 2 NaCl
preparation
Molybdenum trioxide is produced by oxidizing and roasting molybdenum concentrate, which is leached with liquid caustic soda to form sodium molybdate solution, which can be obtained after suction filtration, concentration, cooling, centrifugation and drying.
use
Sodium molybdate is one of the most important molybdates. It is used as a raw material for the manufacture of dyes, molybdenum red pigments, and light-fast color precipitants; it is used for phosphomolybdic acid, sodium phosphomolybdate, molybdate, and molybdenum-containing catalysts , the manufacture of metal corrosion inhibitors and flame retardants for pollution-free industrial cooling water systems; it is also used as analytical reagents for alkaloids, galvanizing, polishing agents, and essential trace components for animals and plants.
