New Introduction to Sodium Borohydride

Posted in General | 13:51

Sodium borohydride is a milder reducing agent, can be used in aqueous solution. It converts selectively aldehydes and ketones the corresponding alcohols in the manufacture of pharmaceuticals and other fine chemicals. It will not react with esters, amides, or carboxylic acids. The reactivity of sodium borohydride can be modified by addition of iodine or methanol in BH3-THF to reduce esters into the corresponding alcohols like the reaction of benzyl benzoate to benzyl alcohol. Sodium borohydride is also used as a hydrogen source for fuel cell systems and a foaming agent for rubbers. Xiangbang Sodium Methoxide Co.Ltd is one of the largest domestic manufacturers of sodium methoxide and sodium methylate solution in China, Our company is one of the "National New & High Technological Enterprises" and "Backbone Enterprises of Fine and Special Chemicals Industrial Base", one of the National Torch Projects.

Chemical reaction of Niobium

Posted in General | 11:11

Niobium is a lustrous, grey, ductile, paramagnetic metal in group 5 of the periodic table, although it has an atypical configuration in its outermost electron shells compared to the rest of the members. Niobium is slightly less electropositive and more compact than its predecessor in the periodic table, zirconium, whereas it is virtually identical in size to the heavier tantalum atoms, owing to the lanthanide contraction. Although its corrosion resistance is not as outstanding as that of tantalum, its lower price and greater availability make niobium attractive for less demanding uses such as linings in chemical plants.

Use of Methanesulfonic acid

Posted in General | 10:37

Methanesulfonic acid is used as an acid catalyst in organic reactions because it is a non-volatile, strong acid that is soluble in organic solvents. Methanesulfonic acid is convenient for industrial applications because it is liquid at ambient temperature, while the closely related p-toluenesulfonic acid (PTSA) is solid. However, in a laboratory setting, solid PTSA is more convenient. Methanesulfonic Acid can be used as solvent, catalyst of alkylation, esterification and polymerization etc., 99% MSA mainly used in pharmaceutical industry, while 70% MSA mainly used in electric plating and other electronic industry. It also can be used in the generation of borane (BH3) by reacting methanesulfonic acid with NaBH4 in an aprotic solvent such as THF or DMS, the complex of BH3 and the solvent is formed. Methanesulfonic acid is considered a particularly suitable supporting electrolyte for electrochemical applications, were stands as an environmentally friendly alternative to other acid electrolytes used in plating processes.
