What does sodium hydride do?
The principal use of sodium hydride is to carry out condensation and alkylation reactions which proceed through the formation of a carbanion (base-catalyzed). The sodium hydride dispersion has been evaluated in comparison with dry sodium hydride, sodium metal, sodamide, and sodium methylate.
What is the common name of sodium hydride?
Sodium hydride is the chemical compound with the empirical formula NaH….Sodium hydride.

What does sodium hydride reduce?
This remarkably simple protocol endows NaH with unprecedented and unique hydride‐donor chemical reactivity. Hydride reduction of polar π electrophiles, such as carbonyl compounds, carbonitriles, and imines, is one of the most fundamental and important molecular transformations in chemical synthesis.
Is sodium hydride expensive?
The sodium hydride system is inherently low-cost, and Table 5 shows that when levelized over the life of the vehicle, the cost of the onboard storage system per kg of hydrogen delivered to the power system is significant.
What happens when I sodium hydride is treated with water?
Sodium hydride reacts with water and produces sodium hydroxide.
What can NaH reduce?
Sodium borohydride will reduce ketones, aldehydes and acid chlorides.
How do you store sodium hydride?
* Store in tightly closed containers in a cool, dry, well- ventilated area away from WATER and MOISTURE. * Sources of ignition, such as smoking and open flames, are prohibited where Sodium Hydride is used, handled, or stored.
Can NaH reduce aldehydes?
It will reduce aldehydes, ketones, esters, carboxylic acid chlorides, carboxylic acids and even carboxylate salts to alcohols. Amides and nitriles are reduced to amines. In each case the partially negative hydrogen reacts with the partially positive carbon of the substrate.
What is sodium Acetylide?
Monosodium acetylide is the salt formed from the acetylide monoanion and a single sodium cation. It is an acetylide and an organic sodium salt. It contains a dicarbide(1-).
Does sodium hydride go bad?
Some of them (like sodium hydride) are often sold as a fine powder mixed with mineral oil, which coats everything and keeps it from igniting. It goes bad too quickly, and an NaH fire is a beast to put out if it really gets going.
