For these reasons, an important industrial use of phosphonates is in cooling waters, desalination systems, and in oil fields to inhibit scale formation. Phosphonates are also regularly used in reverse osmosis systems as antiscalants. Phosphonates in cooling water systems also serve to control corrosion of iron and steel.
Phosphates have low toxicity in the environment but cause nutrient pollution, a major water quality problem in many watersheds. [17] Phosphates in water cause eutrophication of algae which creates conditions favorable to formation of harmful algal blooms. These blooms prevent light and oxygen from getting into the water, leading to the death of ...
Oxidation of phosphonites gives phosphonates: 2 P(OR) 2 R + O 2 → 2 OP(OR) 2 R. Phosphonites can function as ligands in homogeneous catalysis. [3] References
Organophosphorus chemistry is the scientific study of the synthesis and properties of organophosphorus compounds, which are organic compounds containing phosphorus. [1] They are used primarily in pest control as an alternative to chlorinated hydrocarbons that persist in the environment.
Trisodium phosphate has gained a following as a nutritional supplement that can improve certain parameters of exercise performance. [14] The basis of this belief is the fact that phosphate is required for the energy-producing Krebs cycle central to aerobic metabolism. Phosphates are available from a number of other sources that are much milder ...
Aminophosphonates are often prepared by hydrophosphonylation, usually the condensation of imines and phosphorous acid.In the Pudovik reaction or Kabachnik–Fields reaction the esters of phosphorous acid are employed, e.g. diphenylphosphite.
The situation is confusing because of the similarity in name between phosphite and phosphate (a major plant nutrient and fertilizer ingredient), and controversial because phosphites have sometimes been advertised as fertilizers, even though they are converted to phosphate too slowly to serve as a plant's main phosphorus source.
Phosphonates are salts (M 2 HPO 3) or esters (OP(OR) 2 R) of phosphonic acid Subcategories. This category has the following 2 subcategories, out of 2 total. P ...
