506-77-4 chlorine cyanide

Cyanide destmction by alkaline chlorination is a widely used process. With alkaline chlorination, cyanide is first converted to cyanate with hypochlorite [7681-52-9] at a pH greater than 10. A high pH is required to prevent the formation of cyanogen chloride [506-77-4] which is toxic and may evolve in gaseous form at a lower pH. With additional hypochlorite, cyanate is then oxidized to bicarbonate, nitrogen gas, and chloride. The pH for this second stage is 7—9.5 (6). [Pg.163]

This test is performed to determine the amount of cyanide in the sample that would react with chlorine. Not all cyanides in a sample are amenable to chlorination. While HCN, alkali metal cyanides, and CN- of some complex cyanides react with chlorine, cyanide in certain complexes that are tightly bound to the metal ions are not decomposed by chlorine. Calcium hypochlorite, sodium hypochlorite, and chloramine are some of the common chlorinating agents that may be used as a source of chlorine. The chlorination reaction is performed at a pH between 11 and 12. Under such an alkaline condition, cyanide reacts with chlorine to form cyanogen chloride, a gas at room temperature, which escapes out. Cyanide amenable to chlorination is therefore calculated as the total cyanide content initially in the sample minus the total cyanide left in the sample after chlorine treatment. [Pg.140]

Pentamethinestreptocymine Dyes are formed by reaction of bromine cyanide, chlorine cyanide, or 2,4-dinitrochlorobenzene with pyridine and cleavage of the resultant compounds with primary or secondary amines. The tetraacetal of gluta-conaldehyde is also used to form the methine chain [2], The dyes can be used to dye paper. [Pg.254]

C(sp)—Cl bond distances in various acetylenes (Table 28) have a remarkably constant value of ca 163.5 pm and variations due to electron-donating (Me, t-Bu, SiH3) or electron-withdrawing substituents (F, Cl, CN) at the opposite carbon are smaller than the experimental uncertainties. ED and MW for chlorobromoacetylene result in rather different ra and r0 values for the C—Cl bond length and this discrepancy may be due to large-amplitude bending vibration of this linear molecule. A similar, but smaller difference between ra and rs values occurs for chlorocyanoacetylene. The rs value for chlorine cyanide is also in line with the results for the acetylenes. [Pg.56]

CHLORINE CYANIDE (506-77-4) Violent polymerization can be caused by chlorine or moisture. Violent reaction with alcohols, acids, acid salts, amines, strong alkalis, olefins, strong oxidizers. In crude form, this chemical trimerizes violently if catalyzed by traces of hydrogen chloride or ammonium chloride. Prolonged storage may cause the formation of polymers. Alkaline conditions will convert this chemical to cyanide. Corrodes brass, copper, bronze. [Pg.282]
