Sodium bisulfite takes on a wide range of functions as a chemical base and is permitted as a food additive according to Food Grade E Also known as sodium hydrogen sulfite, it is often used as a food additive. A European approval in the classes of additives for antioxidants and preservatives is given under the approval number Eindicated by a corresponding indication of the approval number or the endorsement "sulphurised".
Sodium bisulfite is primarily used as an enzymblocker in order to counteract the cutback in coloring and flavoring substances contained in foods as well as of vitamins. The enzymatic browning, which often occurs in where to buy liquid sodium bisulfite used potato products, can be treated effectively. In where to buy liquid sodium bisulfite, it acts as a reducing agent and the detoxification of chromium-containing wastewater - by reduction of VI-valent to III-valent chromium alternatively, by reduction of hexavalent CrVI to trivalent chromium CrIII.
At the same time, cyanides can be removed in the field of wastewater purification. For this purpose, sodium bisulfite is used as a highly effective reducing agent in the context of the recovery of iodine from chile nitriles as well as in where to buy liquid sodium bisulfite aldehyde and ketone purification of the chemical-technical industry.
The modes of action here are based on an addition reaction with aldehydes or ketones to form bisulfite adducts. This takes place by nucleophilic addition of the sulfur to the carbonyl group with simultaneous formation of a hydroxyalkylsulfonation. Available at TIB Chemicals is a sodium hydrogensulfite solution with a concentration between 38 and 40 mass percent.
Sodium hydrogensulfite is stable only in aqueous solution and therefore available from TIB Chemicals exclusively from solution, a colorless to yellowish liquid. It is approved as a basic substance for the production of cosmetics. It can also serve as a raw material for the production of pulp and chemical pulp. At the same time, however, it is also suitable as a bleaching agent for straw braids, woven fibers or wood sanding.
Accordingly, concentrated sodium bisulfite also performs functions in the reductive purification of large laundry facilities in order to effectively clean yellowed white goods.
However, as a preservative, where to buy liquid sodium bisulfite bisulfite can also be included for the brightening of glue, putty or gelatin. The acidic properties are used to coagulate rubber. This website requires JavaScript enabled. Please enable JavaScript in your browser.
