APPLICATIONS

Diisocyanates (or polyisocyanates) are monomers for polyurethane production. Polyurethane is made from a variety of diisocyanates in conjunction with polyether and polyester polyols as co-reactants by addition polymerization which needs at least two -N=C=O groups. Polyurethanes are widely used in the manufacture of flexible and rigid foams, fibres, coatings, and elastomers. The most common diisocyantes for this reaction are:

GENERAL DESCRIPTION OF CYANATE (ISOCYANATE)

Cyanic acid (also called fulminic acid) is an unstable (explosive), poisonous, volatile, clear liquid with the structure of H-O-CN (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 structure 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). Esters of normal cyanic acid are not known. 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.
