|The Application of Sodium Borohydride
water soluble reductant, mainly used in drug, pulp bleaching, recovery of noble metals and prevention of the occurrence of public nuisances caused by heavy metals. It is reductant of carbonyl compound (aldehyde, ketone, acid, acid amide, acid anhydride, acid halogen, ester, enol ester, imide , lactone), carbonitriding chemicals (azide, diazo salts, hydrazone, imine, nitrile, oxime, nitro compound), peroxide and hydroperoxide; It also can be used to remove color, smell of organic chemicals, used to control pollution and recycle noble metals, the production of drug and fine chemicals, or used in the production and recovery of catalyst.
During transportation, packing damages and dampening should be avoided. Sources of heat, ignition and inflammable materials should be kept away from it. It should be separated from water containing materials, acidic materials and oxidants during storage and transportation process. Kept in cool, dry and ventilating place.
