General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.


Sodium hydride (60% dispersion in mineral oil) (NaH) can be used for a variety of applications such as:
• preparation of a plasticizer for the formation of a solid polymer electrolyte (SPE) for optoelectronic application
• synthesis of heteroaryl thioethers, the common constituents in therapeutic compounds
• preparation of sodium aluminum hydride (NaAlH4), which can be used as a hydrogen storage material(3)
• a base and a reducing agent for the deprotonation of alcohols, phenols, amides, ketones, and different functional groups(4)
• for potential usage in thermal energy storage(5)

Direct intercalation into C60 results in the superconducting material (NaH)4C60.

What is the particle size of Product 452912, Sodium hydride in Mineral Oil?
Particle size is not one of our specifications so we have not tested for it and neither has the vendor. According to literature though, the particle size could range from 5 - 50 um (Condensed Chemical Dictionary, Twelfth Edition).
How do you dispose of Product 452912, Sodium hydride in Mineral Oil?
In accordance with our MSDS, we recommend you contact a licensed waste disposal company to dispose of this material. If you have small quantities to dispose of, the Hazardous Laboratory Chemicals Disposal Guide : 2nd Edition, recommends you wear eye protection, laboratory coat, and nitrile gloves. In the fume hood , mix the hydride with a 1:1:1 mixture by weight of sodium carbonate or calcium carbonate, clay cat litter (bentonite), and sand. Slowly and cautiously add butanol ( about 38 mL/g of hydride) until the reaction ceases. Then add water very carefully until all of the hydride is destroyed. Let stand until solids settle. Decant liquid into the drain. The solid residue may be discarded with normal refuse.
What is the packaging configuration for Product 452912, Sodium hydride in Mineral Oil?
The 5 gram unit is packaged in an amber glass bottle. The 100 gram and 500 gram quantities are packaged in a paint can. The product is in a bag in the can and the can be opened by removing the plastic seal from the top of the can. An 18 L steel drum is used for packaging the 2 kg and 5 kg size.
