Potassium bisulfite

A mixture of 59.5 g of that oily product, 1.B5 liters of benzene and 1 kg of potassium bisulfite in 200 liters of water is stirred at room temperature for two hours. The precipitated bisulfite addition product of the ketone is isolated by filtration and washed with isopropanol and then with ether. Five hundred grams of the adduct is mixed with 119.5 g of potassium cyanide, 292 ml of B5% hydrazine hydrate and 910 ml of water. The mixture is stirred overnight at room temperature after which the product is isolated by filtration. The product is washed 3 times with 250 ml portions of water and then 3 times with 230 ml portions of ether. It is then air dried and vacuum dried at room temperature. The intermediate so produced has the following formula ... 

CONOSOX A complex flue-gas desulfurization process using potassium carbonate solution as the wet scrubbing medium. The product potassium bisulfite is converted to potassium thiosulfate and then reduced with carbon monoxide to potassium carbonate for re-use. The sulfur is recovered as hydrogen sulfide, which is converted to elemental sulfur by the Claus process. Developed by the Conoco Coal Development Company and piloted in 1986. 

Potassium bisulfite reduces fluoroalkylnitroso compounds to the oximes, with the exception that the parent mtrosotnfluoromethane is converted to the corresponding hydroxylamine [90] (equation 72). ArylfluoroaJkylazo compounds are reduced to the hydrazo stage or the fluoroamine by zinc-add, depending on conditions [91] (equation 73) Of the various reagents tested tor selective reduction of ji-fluoroalkyl azides to P-fluoroalkylamines, triphenylphosphine was the best [92] (equation 74). 

The addition-compounds of sodium bisulfite (or potassium bisulfite) with numerous sugars have199a been prepared in a pure state and have been shown to react with aromatic amines under conditions similar to those under which the free sugars react. -Substituted glycosylamines are formed, but the reaction with amino acids was not reported. 

Although com can be adequately steeped in sterile, aqueous solutions of sulfur dioxide or sodium, magnesium or potassium bisulfite (hydrogen sulfite) in the laboratory,164-166 commercial steeping involves microorganisms. Raw com carries natural populations of bacteria, yeasts and molds which are capable of rapid multiplication in aqueous systems. Wet-millers learned early that com steeped at temperatures of 45-55°C was sweet, but that putrefaction and butyric acid or alcohol production... 

In 93 per cent yield by heating a-phenyiethyi alcohol with 5 per cent of sodium or potassium bisulfite. Gauthier and Gauthier, Bull. soc. chim. [4] 53,323 (1933). 

In aqueous solution, potassium metabisulfite forms potassium bisulfite (KHSO3) which exerts a strong reducing effect.

Potassium diazomethanedisuJfonate (secondary). (K03S)2C=N=N. Mol. wt. 278.36. The reagent was prepared by von Pechmann and Manck by reaction of potassium cyanide in aqueous solution with potassium bisulfite to form the sparingly soluble primary (or acid) aminomethane disulfonate (1), which on reaction with... 

Derivation By heating potassium bisulfite until it loses water. 

Polymerization of phenyl or cyclohexyl methacrylate in 2,6-dimethyl-/3-cyclodextrin in water using a potassium persulfate-potassium bisulfite initiator gave better yields and higher molecular weights than obtained with an azo initiator in tetrahydrofuran.234... 

The reaction of chlorosulfonyl isocyanate (CSI) and cyclopentene at -78 °C yielded 2-chlorosulfonyl-2-azabicyclo[3.2.0]heptan-3-one (13), which was transformed to azetidinone 14 with potassium bisulfite. The... 

Aurin crystallizes in fine, red needles from its solution in HCl. It is insoluble in HjO, but soluble in HCl, alcohol, and glacial acetic acid. It forms a colorless compound with potassium bisulfite.
