Lactoperoxidase-catalyzed oxidation of thiocyanate: equilibriums between oxidized forms of thiocyanate

“…Two modes of decomposition of (SCN)2, HOSCN, or OSCN' in aqueous solutions have been described. At low concentrations (<0.5 mM), the rate of disappearance of oxidizing equivalents follows second-order kinetics (Walden & Audrieth, 1928;Wood, 1946). The rate-limiting step was proposed to be the dismutation of two HOSCN molecules, with formation of cyanosulfurous acid (H02SCN) as an intermediate.…”

Hydrazoic Acid and Its Inorganic Derivatives.

“…Birckenbach and Kellermann (34) have shown that the azide radical lies between chlorine and bromine in the relative order of reactivity of various halogen and halogenoid groups. For that reason hydrazoic acid has been termed a "halogenoid" (248) hydracid. When added to solutions of soluble silver, lead, and mercurous salts the corresponding azides are precipitated.…”

A classification of compounds of hydrogen and nitrogen

“…Franklin (20), however, has pointed out that hydrazoic acid is a strong delectronator 3N2H4 + HNOs = /N2H3 N^N2Hs \n?h3 HN3 (15) and may be regarded as a deammonation product of ortho-ammono-nitric acid (16). That such a postulation is in accord with the facts is evidenced N(NH2)6 = HNa + 3NH3 (16) by the solubility of the noble metals in a mixture of hydrochloric and hydrazoic acids and by the nitridizing action of potassium azide in the conversion of potassium cyanide, an ammono-carbonite, to potassium cyanamide, an ammono-carbonate (17). Its preparation by the action KN, + KNC = K2NCN + Ns (17) of fused potassium amide upon potassium nitrate is further support in favor of this postulation.…”
