CAS 16940-66-2
CAS No. 16940-66-2
Chemical Name: Sodium borohydride

borohydride has a strong selective reduction, being able to selectively reduce a carbonyl group is to a hydroxyl group without reacting with the carbon-carbon double bond and triple bond reaction. A small amount of sodium borohydride can restore the nitrile to the aldehyde with the excess amount being reduced to the amine.

Uses

Sodium borohydride (NaBH4) is a versatile reducing agent used in a number of industrial processes. Major applications include organic and pharmaceutical synthesis, wastewater treatment, and paper pulp bleaching. Sodium borohydride plays such a significant role in organic synthesis. It is a good reducing agent which has stable performance and selective reduction. It can be used as the reducing agents of aldehydes, ketones and acid chlorides; also as foaming agent for plastic materials, hydrogenating agent of making dihydrostreptomycin, intermediate of making potassium borohydride, raw materials in synthesizing borane, as well as the treatment agent of paper industry and mercury-containing waste water.

Sodium borohydride provides organic chemists a very convenient and mild means for reduction of aldehydes and ketones. Before this, people usually use metal/alcohol approach to reduce carbonyl compound. Sodium

Releases hydrogen to blow in material.

What are the characteristics of Schiff base, such as chelation, heat resistance, liquid crystal and intrinsic conductivity. The conductivity of Conjugated Poly (Schiff base) doped with iodine can be increased by about 8 orders of magnitude, which makes it reach the level of semiconductor. The doped materials have good stability, electrochemical activity and photoconductivity.

In the conventional state, the molecular chain of poly (Schiff base) is relatively rigid, and the intermolecular force is also strong, so the polymer is insoluble and insoluble. However, the Schiff base synthesized by using trimethylol aminomethane and other solvents directly makes the Schiff base get rid of the difficult situation of polymer processing and characterization, and the conductivity increases.

In order to improve the yield of Schiff base, it is necessary to synthesize Schiff base by the reaction of 3,5-dibromosalicylic aldehyde with trimethylolminomethane, and reduce Schiff base with anhydrous ethanol at room temperature. The results showed that the molar ratio of 3,5-dibromosalicylic aldehyde to trihydroxymethylaminomethane was 1 â?¶ 1, the reaction time was 30 min, the molar ratio of sodium borohydride to 3,5-dibromosalicylic aldehyde trihydroxymethylaminomethane Schiff base was 1.5 1, and the yield of reduced Schiff base was 81.4%.
