History

Sodium molybdate was first synthesized by the method of hydration.[4] A more convenient synthesis is done by dissolving MoO3 in sodium hydroxide at 50-70 °C and crystallizing the filtered product.[3] The anhydrous salt is prepared by heating to 100 °C.

 

 

MoO3 + 2NaOH + H2O → Na2MoO4·2H2O

Uses

The agriculture industry uses 1 million pounds per year as a fertilizer. In particular, its use has been suggested for treatment of whiptail in broccoli and cauliflower in molybdenum-deficient soils.[5][6] However, care must be taken because at a level of 0.3 ppm sodium molybdate can cause copper deficiencies in animals, particularly cattle.[3]

 

Sodium molybdate is used in industry for corrosion inhibition, as Sodium molybdate is a non-oxidizing anodic inhibitor.[3] The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine, and improves the corrosion protection of carboxylate salt fluids.[7]

In industrial water treatment applications where galvanic corrosion is a potential due to bimetallic construction, the application of sodium molybdate is preferred over sodium nitrite. Sodium molybdate has the advantage in that the dosing of lower ppm’s of molybdate allow for lower conductivity of the circulating water. Sodium molybdate at levels of 50-100 ppm offer the same levels of corrosion inhibition that sodium nitrite at levels of 800+ ppm. By utilizing lower concentrations of sodium molybdate, conductivity is kept at a minimum and thus galvanic corrosion potentials are decreased.[8]

 

Reactions

When reacted with sodium borohydride, molybdenum is reduced to a lower valent oxide:[9]

 

 

Na2MoO4 + NaBH4 + 2H2O → NaBO2 + MoO2 + 2NaOH + 3H2

Sodium molybdate reacts with the acids of dithiophosphates:[3]

 

 

Na2MoO4 + 

(R = Me, Et)

(RO)2PS2H

→ [MoO2(S2P(OR)2)2]

which further reacts to form [MoO3(S2P(OR)2)4].

 

 

Safety

Sodium molybdate is incompatible with alkali metals, most common metals and oxidizing agents. It will explode on contact with molten magnesium. It will violently react with interhalogens (e.g., bromine pentafluoride; chlorine trifluoride). Its reaction with hot sodium, potassium or lithium is incandescent.[10]

Sodium Molybdate is a source of molybdenum.

Molybdenum’s fundamental role in the human body is as a constituent of molybdoenzymes; some important molybdoenzymes are xanthine oxidase, sulphite oxidase and aldehyde oxidase. These are involved in the metabolism of sulphur amino acids and purine. By converting sulphite to sulphate, sulphite oxidase aids the metabolising of the sulphur amino acids methionine and cysteine, a process that is crucial to human health. This also helps the body reduce the harmful effects of sulphites generally.

 

PROPERTIES of Sodium Molybdate

 

Sodium molybdate is an odorless, white, hygroscopic solid (small scales or flakes). It is slightly soluble in water, insoluble in ethanol, acetone. Stable under ordinary conditions. Incompatible with alkali metals, most common metals and strong oxidizing agents.

 

Other uses of Sodium Molybdate

– manufacture of molybdated lubricants, pharmaceuticals, alkoloids, dyes, pigments,

– buffing compound for galvanizing,

– retardants and metal depressants,

– descaling agents, bleaching agents,

– water treatment.

It is used in the industry for corrosion inhibition, as it is a non-oxidizing anodic inhibitor. The addition of sodium molybdate significantly reduces the nitrite requirement of fluids inhibited with nitrite-amine, and improves the corrosion protection of carboxylate salt fluids.In industrial water treatment applications where galvanic corrosion is a potential due to bimetallic construction, the application of sodium molybdate is preferred over sodium nitrite. Sodium molybdate has the advantage in that the dosing of lower ppm on molybdate allow for lower conductivity of the circulating water.

 

Sodium molybdate is used as source of molybdate and it is often used in the form of Sodium molybdate dihydrate. It inactivated both the active and inactive form of the gluco corticoid receptor complex in murine models. It has been shown to reduce the emission of hydrogen sulfide from swine manure with the use of nitrites.

Molibden geçi metallerinden olup saf halde gümüümsü beyaz renkli ve çok serttir. Ergime scakl oldukça yüksektir. Az miktardaMolybdate de sodiumavesiyle çeliin daha da sertletirilmesi salanabilir. Molibden bitkilerin beslenmesinde de önemli olup baz enzimlerde yer alr.

sveçli kimyac Carl Wilhelm Scheele 1778’de, o döneme dein bir kurun cevheri ya da grafit olduu sanlan mineralin (molibdenit) bilinmeyen bir metalin sülfür bileii olduunu gösterdi. sveçli kimyac Peter Jacob Hjelm de 1782’de molibdeni metal halinde ayrd ve Yunanca “kuruna benzer” anlamna gelen molybdos sözcüünden esinlenerek adlandrd.

Sodyum molibdat wulfenit (PbMoO4) veya powellit (CaMoO4) gibi minerallerde bulunursa da, asl ticari molibden kayna molibdenittir (MoS2). Molibden dorudan madencilik yoluyla ve bakr madencilii srasnda yan ürün olarak ta elde edilebilir. Molibden, cevherlerinde %0.01 den %0.5 e deien miktarlarda bulunur. Dünya molibden madenciliinin yaklak yars ABD’de (Phelps Dodge Corporation) yaplmaktadr.

Sodyum molibdat Kimyasal özellikleri bakmndan krom ve wolfram ile benzerlik gösteren molibden; yüksek ergime ve kaynama noktas, yüksek s dayanm, yüksek s iletkenlii ve düük termal genleme gibi üstün özelliklere sahiptir. Molibden 2623 °C de ergir. Bu özellii ile metaller arasnda altnc sray alr. 4639 °C de kaynayan molibden, soukta havadan etkilenmez, akkor halindeyken oksitlenir, nitrik ve sülfürik asitlerden etkilenir, yüksek scaklkta su buharn ayrtrr. Molibden’in younluu 10,28 gr/cm3 tür.

Sodyum molibdat Kullanm Alanlar

 

Tarm endüstrisi ylda 1 milyon sterlinlik bir gübre kullanyor. Özellikle, molibden eksiklii olan topraklarda brokoli ve karnabahar tohumlarnn ilenmesi için kullanlmas önerilmitir.

Bununla birlikte, 0.3 ppm’lik bir seviyedeki sodyum molibdatn hayvanlarda, özellikle srlarda bakr eksikliklerine neden olabilecei için dikkat edilmelidir.

Korozyon önleme için endüstride kullanlr, çünkü oksitleyici olmayan anodik bir inhibitördür.

Sodyum molibdat ilavesi, nitrit-amin ile inhibe edilen svlarn nitrit ihtiyacn önemli ölçüde azaltr ve karboksilat tuzu akkanlarnn korozyon korumasn gelitirir.

Galvanik korozyonun bimetal yapdan dolay potansiyel olduu endüstriyel su artma uygulamalarnda, sodyum nitritten çok sodyum molibdat uygulamas tercih edilir.

Sodyum molibdat, daha düük ppm’lik molibdat dozajlamann dolamdaki suyun daha düük iletkenliine sahip olmas avantajna sahiptir. 50-100 ppm düzeyindeki sodyum molibdat, 800 + ppm seviyelerinde sodyum nitrit olan korozyon inhibisyonu ile ayn seviyeleri sunar.

Daha düük konsantrasyonlarda sodyum molibdat kullanarak iletkenlik minimumda tutulur ve böylece galvanik korozyon potansiyelleri azaltlr
