Sodium chlorite, hazards with

CNC CHLORITE is a modified sodium chlorite product designed to give the excellent bleaching with fiber protection that is normal for sodium chlorite but with the added advantage of anti-corrosion properties to stainless steels and reduced hazards in handling.

For the synthesis of amino acids, the reaction of an a-haloalkyl boronic ester 4 with sodium azide and a phase-transfer catalyst in dichloromethane/water requires a large excess of azide in order to form the a-azidoalkyl boronic ester 5 with only 1-2% epimer34. With the exception of R1 = benzyl, where epimerization of 4 is relatively rapid, bromoalkyl boronic esters are preferred. Chloroalkyl boronic esters react so slowly that the azide and dichloromethane may generate hazardously explosive diazidomethane65,66. Chain extension of 5 to 6 proceeds normally. Sodium chlorite, which is known to oxidize aldehydes to carboxylic acids67-69, also oxidizes a-chloroalkyl boronic esters to carboxylic acids34. The azido acid is hydrogenated to the amino acid. 

Chlorine Dioxide. Chlorine dioxide, C102. is a gas that is more hazardous than chlonne. Large amounts for pulp bleaching are made by several processes in which sodium chlorate is reduced with chloride, methanol, or sulfur dioxide in highly acidic solutions by complex reactions. For most other purposes chlorine dioxide is made from sodium chlorite. 

Scouring and bleaching of jute with sodium chlorite with an acceptable whiteness can be achieved, but the process is a time consuming two step process. Moreover, sodium chlorite is metal corrosive and health hazardous.
