Cupric cyanide

Potassium cupro-cyanide is the most convenient form in which cuprous cyanide can be used in Sandmeyer s Reaction. It is prepared by adding an excess of potassium cyanide to copper sulphate solution, whereby the cupric cyanide which is formed immediately breaks down to give cuprous cyanide and cyanogen, and the cuprous cyanide then dissolves in the excess of potassium... [Pg.191]

The 3-cyanophenthiazine used as starting material can be prepared by the action of cupric cyanide on 3-chlorophenthiazine in boiling quinoline. It has a first melting point of about 185 C and a second of about 203 to 205 C. [Pg.397]

Cupric cyanide, Cu(CN)2.—The cyanide is obtained as a brownish-yellow precipitate by the interaction of solutions of potassium cyanide and cupric sulphate, but it is very unstable, decomposing at ordinary temperatures into cupric cuprous cyanide, Cu[Cu.(CN)2]2,5H20, with evolution of cyanogen. On heating, it is converted into cuprous cyanide. With hydrazine cyanide it unites to form a monohydrazinate, Cu(CN)2,N2H4, yellow needles insoluble in water, m.p. 160° to 162° C.7... [Pg.287]

Derivation Addition of potassium cyanide to a solution of copper sulfate cupric cyanide is precipitated. This can be dried but is not stable. [Pg.332]

Cyanogen is more conveniently prepared by warming an aqueous solution of copper sulphate and potassium cyanide. A double decomposition between the two salts results in the formation of cupric cyanide and potassium sulphate. The former, at a comparatively low temperature, decomposes with the formation of cuprous cyanide and cyanogen. The reactions are expressed by the equations,—... [Pg.237]

The number and variety of ion-specific electrodes is rapidly increasing with no end in sight. At the present writing, it is possible to use such electrodes to determine, either by direct or indirect measurement, ionic concentrations of the following species ammonia, bromide, cadmium, calcium, chloride, cupric, cyanide, fluoride, fluoroborate, iodide, lead, nitrate, perchlorate, potassium, sulfide, sodium, sulfur dioxide, and thiocyanate, all by direct measurement, and by titration methods aluminum, boron, chromium, cobalt, magnesium, mercury, nickel, phosphate, silver, sulfate, and zinc. [Pg.113]
