performance : microcrystalline specifications : 60% NaH3%
solubility : insoluble in all organic solvents and ammonia and amines
mineral oil diluent, the flash point of 403%

share : 0.84-0.86

mineral oil with a broad range of hydrocarbon free Compatibility without affecting the activity of sodium. Examples sec heptane, ethyl ether, ethyl ether and toluene.

thermal stability : sodium heat, beginning in 255 dissociation. Pressure on the right balance of temperature can be used to express the following formula :

Log10Pmm =- 6100/TK +11.66 (1)

300 more oil will be sodium attacks.

water reactive Attention! Dispersion sodium and water to form hydrogen gas and sodium hydroxide reaction was ferocious, and the heat. The hydrogen combustion will occur.

applications :

condensation -- Oil of acetylcholine in sodium acetate, Claisen, Stobbe, Dieckmann and related condensation condensing agent to play the role of the will edge with metallic sodium and sodium alkoxide same. With its mixture with other reduction in comparison, there is the following advantages :

(1) more effective, and the response was much faster;

(2) do not need big excessive;

(3) without having to take the alcohol distillation out to promote condensation a, and there was no other form of alcohol;

(4) to avoid such a reduction reaction;

(5) from the reaction of hydrogen can be measured level.

alkylation -- aromatic and heterocyclic amines such as 2-aminopyridine and phenothiazine in the alkylation of toluene used - dimethyl formamide circumstances High Yield easy to complete. DMF is a concentration of control of the reaction rate for the score.

Availability :

normally five kilograms, 10 kilograms of packaging ranging from small 40 or 50 kilograms of packaged for sale. But can accept adapted to the specific needs of the particular specification packaging requirements.

toxicity and where :

sodium dispersion believed to be the intake of toxic products, which react with water to form sodium hydroxide, and may react with the acid caused inverse gas in the intake of primers do not vomit. Le immediately checked.

believed sodium dispersion of the skin and eyes are corrosive, the same reason as sodium influx in the case will produce sodium hydroxide. When contact with the eyes, immediately left on the skin material scouted, and then wash with water access sites. If we continue to stimulate the flu, pester the priest.
sodium hydride not dust. But the reaction of materials can release a fine mist of caustic soda. Happened in the case of inhalation immediately mouthwash, and transferred to the fresh air under. Le immediately checked.

shall take all necessary measures to avoid ingestion, inhalation or sodium reaction products, but also to avoid any contact with the skin.

disposal and storage :

sodium in the oil dispersion is not a fire materials. When glued to the vessel wall and the lid on the material is still moist air combustion. Therefore, the disposal of sodium hydride when required to wear rubber gloves to protect, clothing and face masks. Disposal of dispersion should be disposed of like other materials, like hygroscopicity. Costumes dispersion containers should be stored cold, dry, tight tight closure. Transfer to other containers scattered body, we must first Fold containers drying, cooling and nitrogen purge. The reaction of sodium hydride to the appropriate generic reactor for. Although that 603% of NaH Dispersions in the disposal system up is a safe and stable material, but placed CNPC from sodium hydride particles flowing open to the tendency of scattered body to stay on top of the containers, disposal, and should, as pointed out by the treatment.

fire :

Attention! Be ready nausea Firestone Dust. Not water, soda acid, chemicals or carbon dioxide fire extinguishing. The only adaptation of nitrogen-driven fire extinguisher powder extinguishing agent.

special packaging :

order to feed safety, and convenience, according to customer demand "within the soluble bags" (that is, sodium hydride materials and put together kits within Reactor reaction) sodium placed polyethylene bag placed in metal drums Transportation. In accordance with the needs of customers using soluble packaging (within 70 ° C melting bags of solvent without any other influence)

Notes : Feeding sodium may even put together bags within reactor.
