Potassium cyanate is an inorganic compound with the formula KOCN (sometimes denoted KCNO〔Recreation of Wöhler’s Synthesis of Urea: An Undergraduate Organic Laboratory Exercise'' James D. Batchelor, Everett E. Carpenter, Grant N. Holder, Cassandra T. Eagle, Jon Fielder, Jared Cummings The Chemical Educator 1/Vol .3,NO.6 1998 ISSN 1430-4171 (Online article )〕). It is a colourless solid. It is used to prepare many other compounds including useful herbicide. Worldwide production of the potassium and sodium salts was 20,000 tons in 2006.〔Peter M. Schalke1, "Cyanates, Inorganic Salts" Ullmann's Encyclopedia of Industrial Chemistry2006, Wiley-VCH, Weinheim. . Article Online Posting Date: July 15, 2006〕
==Structure and bonding==
Cyanate is isoelectronic with carbon dioxide and with azide, being linear. The C-N distance is 121 pm, about 5 pm longer than for cyanide.〔Jursík, F. (2001). Anorganická chemie nekovů (1. vydání). VŠCHT Praha. ISBN 80-7080-417-3〕 Potassium cyanate is isostructural with potassium azide.〔T. C. Waddington "Lattice parameters and infrared spectra of some inorganic cyanates" J. Chem. Soc., 1959, 2499-2502. 〕
