Methylphosphonic acid is an organophosphorus compound with the chemical formula CH 3 P(O)(OH) 2. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.
Methylphosphinic acid is a monobasic acid, the simplest of the phosphinic acids. A central phosphorus atom is connected to a hydroxy group, a hydrogen atom, a methyl group and an oxygen. A central phosphorus atom is connected to a hydroxy group, a hydrogen atom, a methyl group and an oxygen.
ATMP can be synthesized from the Mannich-type reaction of ammonia, formaldehyde, and phosphorous acid, in a manner similar to the Kabachnik–Fields reaction. [ 1 ] [ 2 ] Properties
Phosphonates are esters of phosphonic acid and have the general formula RP(=O)(OR') 2. Phosphonates have many technical applications, a well-known member being glyphosate, better known as Roundup. With the formula (HO) 2 P(O)CH 2 NHCH 2 CO 2 H, this derivative of glycine is one of the most widely used herbicides.
VX is an odorless and tasteless [13] [14] chiral organophosphorous chemical with a molecular weight of 267.37 g/mol. [15] Under standard conditions it is an amber-coloured liquid with a boiling point of 298 °C (568 °F), and a freezing point of −51 °C (−60 °F). [16]
It will react with thionyl chloride to produce methylphosphonic acid dichloride, which is used in the production of sarin and soman nerve agents. Various amines can be used to catalyse this process. [3] It can be used as a sarin-simulant for the calibration of organophosphorus detectors.
Can we imagine ourselves back on that awful day in the summer of 2010, in the hot firefight that went on for nine hours? Men frenzied with exhaustion and reckless exuberance, eyes and throats burning from dust and smoke, in a battle that erupted after Taliban insurgents castrated a young boy in the village, knowing his family would summon nearby Marines for help and the Marines would come ...
It can be oxidized to methylphosphonous acid: MePH 2 + O 2 → MeP(H)O 2 H. It protonates to give a phosphonium ion: MePH 2 + H + → MePH 3 + With strong bases, it can be deprotonated to give methylphosphanide derivatives: MePH 2 + KOH → K[MePH] + H 2 O
