Sodium borohydride/Density
How do you dissolve sodium borohydride?
It is recommend to use alcohols or ethrs because Sodium borohydride is soluble in alcohols and certain ethers. It’s a very common commercial reagent. I think you are using water as solvent in your reaction. You can prepare sodium borohydride solution using water also.
What is the density of sodium borohydride in g mL?
Its density is 1.035 g mL-1. In temperatures higher than 70 °C, sodium borohydride may ignite in air (flash point 70 °C).
Why does sodium borohydride need a protic solvent?
NaBH4 reacts very slowly with protic solvents at room temperature because B (2.04) and H electronagativities are comparable . So reactions with NaBH4 can be easily conducted using protic solvent like ROH. However, NaBH4 decomposes with -COOH which need to be protected by forming its Na salts by reacting with NaOH .
What is the formula of sodium borohydride?
NaBH4
Sodium borohydride/Formula
How does sodium borohydride reduce?
SODIUM BOROHYDRIDE Reduces aldehydes and ketones to corresponding alcohols. Sodium borohydride is not reactive to esters, epoxides, lactones, carboxylic acids, nitro compounds and nitriles, but reduces acyl chlorides.
Which of the following is reduced by sodium borohydride?
Sodium borohydride is a relatively selective reducing agent. Ethanolic solutions of sodium borohydride reduce aldehydes and ketones in the presence of epoxides, esters, lactones, acids, nitriles, or nitro groups. Reduction of aldehydes is straightforward.
What is sodium borohydride soluble in?
Water
Alcohol
Sodium borohydride/Soluble in
Sodium borohydride is soluble in protic solvents such as water and lower alcohols. It also reacts with these protic solvents to produce H2; however, these reactions are fairly slow. Complete decomposition of a methanol solution requires nearly 90 min at 20 °C.
What is the density of Benzil?
1.23 g/cm³
Benzil/Density
Does NaBH4 reduce epoxide?
Sodium borohydride is a relatively selective reducing agent. Ethanolic solutions of sodium borohydride reduce aldehydes and ketones in the presence of epoxides, esters, lactones, acids, nitriles, or nitro groups.
What is the function of sodium borohydride?
Sodium borohydride (NaBH4) is a reagent that transforms aldehydes and ketones to the corresponding alcohol, primary or secondary, respectively.
What is sodium borohydride mainly used for?
Sodium Borohydride is a white, odorless powder or pellet. It is used for bleaching wood pulp, as a blowing agent for plastics, and as a reducing agent for aldehydes and ketones.
