Codenamed "Project Mars", [1] the 32X was designed to expand the power of the Genesis and serve as a holdover until the release of the Sega Saturn. [2] Independent of the Genesis, the 32X used its own ROM cartridges and had its own library of games, as well as two 32-bit central processing unit chips and a 3D graphics processor. [ 1 ]
Cyanate is the derived anion of isocyanic acid, H−N=C=O, and its lesser tautomer cyanic acid (a.k.a. cyanol), H−O−C≡N. Any salt containing the ion, such as ammonium cyanate, is called a cyanate. The cyanate ion is an isomer of the much-less-stable fulminate anion, CNO − or [C − ≡N + −O −]. [1]
Low-temperature photolysis of solids containing HNCO creates the tautomer cyanic acid H−O−C≡N, also called hydrogen cyanate. [15] Pure cyanic acid has not been isolated, and isocyanic acid is the predominant form in all solvents. [2] Sometimes information presented for cyanic acid in reference books is actually for isocyanic acid ...
The main use of sodium cyanate is for steel hardening. [2]Sodium cyanate is used to produce cyanic acid, often in situ: . NaOCN + HCl → HOCN + NaCl. This approach is exploited for condensation with amines to give unsymmetrical ureas:
Fulminic acid was long believed to have a structure of H–O–N + ≡C −.It wasn't until the 1966 isolation and analysis of a pure sample of fulminic acid that this structural idea was conclusively disproven. [3]
It is a moderately strong acid, [10] with a pK a of 1.1 at 20 °C and extrapolated to zero ionic strength. [11] One of the thiocyanic acid tautomers, HSCN, is predicted to have a triple bond between carbon and nitrogen. Thiocyanic acid has been observed spectroscopically. [12] The salts and esters of thiocyanic acid are known as thiocyanates.
KOCN is prepared by heating urea with potassium carbonate at 400 °C: . 2 OC(NH 2) 2 + K 2 CO 3 → 2 KOCN + (NH 4) 2 CO 3. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO 2 CNHC(O)NH 2), as well as unreacted starting urea, but these species are unstable at 400 °C.
