GENERAL
DESCRIPTION & APPLICATIONS
|
Cyanic
acid (also called fulminic acid) is an unstable (explosive),
poisonous, volatile, clear liquid with the structure
of H-O-C¡ÕN (the oxoacid formed from the pseudohalogen
cyanide), which readily polymerizes to cyamelide and
fulminic acid. Cyanuric acid (also called pyrolithic
acid), white monoclinic crystal with the stucture of
[HOC(NCOH)2N],
is the compound of polymerized cyanic acid. Cyanic acid
hydrolyses to ammonia and carbon dioxide in water. Its
salts and esters are cyanates (or called fulminates).
There is another isomeric cyanic acid with the structure
of H-N=C=O, which is called isocyanic acid. Its salts
and esters are isocyanates. Cyanates (or Isocyanates)
are used in the manufacturing pharmaceuticals, pesticides,
textile softener, lubricants and industrial disinfectants
through the conversion to polycyclic compounds (such
as hydantoins and imidazolons) They are used as plastic
additives and as heat treatment salt formulations for
metals. m-Tolyl
Isocyanate is used as an Intermediate
mainly for the manufacture of agrochemicals. |
