Optical brighteners and raw materials for dyes
Cyanuric chloride plays an important role in lots of applications. Be it stadium seats or your colorful favourite dress. Be it high quality paper or that white shirt for special occasions.
Half a century of experience in manufacturing, handling, processing, and marketing cyanuric chlorides have made Evonik a leading supplier of this product.
Cyanuric chloride is one of the most important heterocyclic compounds. The possibility to selectively substitute the three chlorine atoms, coupled with the stable triazine ring, allows for a broad application spectrum.
Literature sources mention cyanuric chloride for the first time in 1827. Its importance as a valuable and versatile intermediate, however, was recognized only beginning in the 1950’s, when Evonik (former Degussa) started its first pilot plant production in Mainz-Mombach (Germany). It was 1958 when the first commercial production was set up in Wesseling (Germany). Since then we have been continuously supplying our customers with highest reliability.
HIGH PRODUCT QUALITY STANDARDS
Evonik is able to offer a variety of different grades and supply forms of cyanuric chloride. All products are of very high quality standard. Whether solid or liquid, we can meet all your requirements.
These are compounds which absorb invisible UV-light and emit visible light primarily in the blue spectral range. The bluish fluorescence generated makes the yellow or yellowish substrates appear whiter.
Optical brighteners are therefore used in detergents, for the finishing of textiles, and in the manufacture of highly refined paper.
Cyanuric chloride is an important raw material for the production of numerous reactive dyes. Reactive dyes form a chemical bond with cellulose, the main component of cotton fibers. Other fibers that have nucleophilic groups can also enter into a covalent bond with the triazine substituents: that is, the dye is chemically fixed on the fiber. The result is a high-grade, non-fading, colorfast dyeing.
Cyanuric chloride is a main component in the synthesis of UV-light stabilizers, which are used frequently in plastics.
The UV-light stabilizers are either UV-absorbers or radical scavengers. They improve the functional life time of plastic materials, and prevent discoloration and brittleness.
