Industrial Uses
It is estimated that 70% of cyanuric chloride is used in the preparation of the triazine-class pesticides, especially atrazine. Such reactions rely on the easy displacement of the chloride with nucleophiles such as amines:
- (ClCN)3 + 2 RNH2 → (RNHCN)(ClCN)2 + RNH3+Cl-
Other triazine herbicides, such as simazine, anilazine and cyromazine are made in an analogous way.
Cyanuric chloride is also used as a precursor to dyes and crosslinking agents. The largest class of these dyes are the sulfonated triazine-stilbene optical brighteners (OBA) or fluorescent whitening agents (FWA) commonly found in detergent formulas and white paper. Many reactive dyes also incorporate a triazine ring. They are also manufactured by way of the chloride displacement reaction shown above.

Famous quotes containing the word industrial:
“... men and women are not yet free.... The slavery of greed endures. Little child workers, the hope of the future, are sacrificed to industry. Young men are sent out by the billion to die for profits.... We must destroy industrial slavery and build industrial democracy.... The people everywhere must come into possession of the earth [second, third, and fourth ellipses in source].”
—Sara Bard Field (1882–1974)
“Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid- twentieth century.”
—Noam Chomsky (b. 1928)
