What are phosphonates?

occasionally called phosphites, phosphonate is salt or ester of one of the family of phosphone acids. The simplest-non-abstitution-phosphonic acid is H- (Mon)-(OH) _{2 , crystalline white solid obtained by reaction of phosphoric oxide with water. Two of the hydrogen atoms are connected to oxygen atoms and are more acidic than lone hydrogen connected directly to the phosphorus atom. Sodium can form a mono- or di-basic salt of phosphonic acid, with a discount with a chemical structure, h-po- (she) 2 😞 5h Dimethylfosphonate is a liquid ester that is cooked at 340 ° F (171 ° C); Its chemical structure is written H-po- (Och 3 ) 2 .}

The simplest phosphonic acid derivatives, such as the above structures, leave the hydrogen atom connected directly to the phosphorus. However, it can be replaced. One simple example of this methylfosphonic acid, ch _{3 (OH) 2 in which hydrogen is replacedHyl's group, ch 3 . Methylfosphonic acid salt is written in the 3 (she) 2 , while the diethylester-diethylmethylfosphonate structure is written. Aryl derivatives can also be produced, in which hydrogen is replaced by an aromatic organic structure such as phenyl (-C 6 5 ), NAFTYL (-C}

Such a wide range of chemical structures allows considerable reaction options; The textbooks were written only on phosphonate chemistry. There is also a wide range of fosphonates applications, for example in the design of materials and industrial cleaning agents, as well as AS in creating biologically active compounds. They are used to inhibit scale formation and to remove rust. Organic phosphonates are importantIn the development of diseases of antibiotics and fungicides for use from the application of the lawn golf course to the protection of the roots of the avocado. Fosphonates are even used as intermediates in the production of synthetic DNA.

Although many useful compounds are publicly cited for the health risks that may represent, there is little outrage through phosphonates. The Hera initiative, the European Volunteer Agency, suggests that the three main phosphonates used in the home - ATMP, HEDP and DTPMP - are safe and should not cause any concerns about consumers. Some phosphonates in the form of acid are risks, even if they do other strong acids. Mono-salities or esters of phosphonic acids do not have both acidic hydrogen atoms, and thus still maintain their acidic reactivity. Of course, as with other chemicals, all material security data should be carefully read and safety proposals were used.
