Highly reactive and extremely useful in many combinations
Phosphorus is one of the Earth’s most reactive and, if skillfully combined, most versatile elements. At our site in Knapsack, Germany, we use it to make high-quality phosphorus chemicals as well as the tailored phosphoric acid esters of our Hordaphos® line.
First-rate phosphorus chemicals and phosphate ester innovations
Phosphorus has a long history of use at our German site, which is among the largest European sources for some of its derivatives. From white phosphorus, we produce stabilized grades of red phosphorus for advanced pyrotechnics as well as high-quality polyphosphoric acids and phosphorus pentoxide. These inorganic compounds are widely used in the production of surfactants, colorants, pharmaceuticals and vitamins, and they also serve as raw materials for our own organophosphorus innovations.
By carefully controlling reaction partners and conditions, we create tailor-made phosphoric acid esters for a wide array of applications. Marketed under our well-known Hordaphos® brand, these versatile phosphate esters are used as powerfully acidic yet non-corrosive ingredients in cleaning products, antistatic and anti-foaming agents in laundry detergents, and multifunctional additives in inks, paints and coatings. By tweaking the length of their alkyl chains, they can be customized for these as well as many other applications.
