Are phosphonates bad for the environment?
Are phosphonates bad for the environment?
‘Phosphorus, in the form of phosphates or phosphonates, helps wash clothes and dishes, especially in hard water, but its release into waterways can lead to algal blooms that stifle fish and other aquatic life,’ it says.
Is Persil eco-friendly?
ECO CLEANING PRODUCTS At Persil we are working hard to make our products and packaging kinder to our planet. In our liquid detergents, for example, we have boosted our products with effective plant-based stain removers and are now using bottles made from 50% recycled plastic that are 100% recyclable.
What are phosphonate groups used for in biology?
In biology and medicinal chemistry, phosphonate groups are used as stable bioisoteres for phosphate, such as in the antiviral nucleotide analogue, Tenofovir, one of the cornerstones of anti-HIV therapy.
What is synthesis of phosphonates?
Synthesis of phosphonates. A copper-catalyzed reaction of phosphorus nucleophiles with diaryliodonium salts at room temperature delivers products of a P-C bond formation in high yields within a short reaction time of 10 min. The method can be easily adapted to large-scale preparations. With unsymmetrical iodonium salts,…
What is the role of phosphonates in water softening?
Phosphonates are effective chelating agents. That is, they bind tightly to di- and trivalent metal ions, which is useful in water softening. In this way, they prevent formation of insoluble precipitates (scale). The binding of these ligands also suppresses the catalytic properties of metal ions. They are stable under harsh conditions.
What is phosphonate 2-aminoethylphosphonic acid?
The naturally occurring phosphonate 2-aminoethylphosphonic acid was first identified in 1959 in plants and many animals, where it is localized in membranes. Phosphonates are quite common among different organisms, from prokaryotes to eubacteria and mushrooms, mollusks, insects and others.
