Phosphonate salts are the result of deprotonation of phosphonic acids, which are diprotic acids: RPO(OH)2 + NaOH → H2O + RPO(OH)(ONa) (monosodium phosphonate) RPO(OH)(ONa) + NaOH → H2O + RPO(ONa)2 (disodium phosphonate) Phosphonate esters are the result of condensation of phosphonic acids with alcohols.
How phosphorus acid is prepared?
On an industrial scale, the acid is prepared by hydrolysis of phosphorus trichloride with water or steam: PCl3 + 3 H2O → HPO(OH)2 + 3 HCl.
Are phosphates and phosphonates the same?
Phosphonates are generally capable of offering the same level of scale control as phosphates but can be included in formulations at concentrations one order of magnitude lower than phosphates. ... Although not readily biodegradable, phosphonates are not immune to photodegradation, hydrolysis or biodegradation over time.
Are phosphonates harmful?
Phosphonates are of low to moderate toxicity to people. If phosphonates are ingested, they are not easily absorbed by the digestive system and are rapidly eliminated from the body via faeces. Intake through the skin is also unlikely to cause harm due to the low potential for phosphonates to accumulate in the body.
What do phosphonates do?

Does phosphite exist?
Phosphite ( ; Phi), a reduced form of phosphate ( ; Pi), is widely marketed as either a fungicide or fertilizer or sometimes as a biostimulant.
What makes up a phosphate group?
Phosphate group: A functional group characterized by a phosphorus atom bonded to four oxygen atoms (three single bonds and one double bond). One of these oxygen atoms must be bonded to another atom; if not, the structure is a phosphate ion.
Which ions make up phosphorous acid?
One group of these derivatives is composed of salts containing the phosphate ion (PO43−), the hydrogen phosphate ion (HPO42−), or the dihydrogen phosphate ion (H2PO4−), and positively charged ions such as those of sodium or calcium; a second group is composed of esters, in which the hydrogen atoms of phosphoric acid ...
Is phosphorus basic or acidic?
Phosphorus is a soft base so the complexes most often involve a soft metal atom or ion. The dialkyl phosphites react with chlorine to give a chlorophosphite. They can also be hydrolyzed to give either a monoalkyl phosphite or free H3PO3. A salt that serves as a reactive intermediate is formed by reaction with sodium.
