Specification

The Sodium molybdate(VI) dihydrate with CAS registry number of 10102-40-6 is also known as Sodium molybdate dihydrate. The IUPAC name is Disodium dioxido(dioxo)molybdenum dihydrate. It belongs to product categories of Water Ttreatment Chemicals. Its EINECS registry number is 231-551-7. In addition, the formula is H₄MoNa₂O₆ and the molecular weight is 241.95. This chemical is a white crystals or powder and soluble in water, insoluble in alcohol. What's more, it should be sealed in ventilated and dry place. It is used as catalyst, precipitant and used for preparation of dye, molybdenum red pigment or molybdenum salt.

Physical properties about Sodium molybdate(VI) dihydrate are: (1)H-Bond Donor: 2; (2)H-Bond Acceptor: 6; (3)Exact Mass: 243.885735; (4)MonoIsotopic Mass: 243.885735; (5)Topological Polar Surface Area: 82.3; (6)Heavy Atom Count: 9; (7)Complexity: 62.2; (8)Covalently-Bonded Unit Count: 5.

Preparation of Sodium molybdate(VI) dihydrate: it is prepared by caustic extraction reaction of molybdenum. Firstly, molybdenum is roasted and dissolved with caustic to generate sodium molybdate solution. Then product is obtained by leaching, evaporation, cooling, crystallization, centrifugation and drying at the temperature of 70-80 °C.
