Chemische Eigenschaften
colourless liquid
Verwenden
Dimethyl methylphosphonate is used as a catalyst and a reagent in organic synthesis for the conversion of esters to ketophosphonates. It is an additive for the synthesis of unsaturated polyester resin which has flame retardant high phosphorous and UV-cured epoxy acrylate. It finds application as hydraulic fluids as well.
Allgemeine Beschreibung
Clear colorless liquid with a pleasant odor.
Air & Water Reaktionen
Highly flammable. Water soluble. Hydrolyzes slowly upon contact with water.
Reaktivit?t anzeigen
Dimethyl methylphosphonate is incompatible with strong oxidizing agents and strong bases. Dimethyl methylphosphonate reacts with organic halides at 302-392° F. When heated to temperatures greater than 302° F, Dimethyl methylphosphonate will act as an alkylating agent with basic nitrogen compounds and phenols. Dimethyl methylphosphonate reacts with enol lactones. Dimethyl methylphosphonate has plasticizing properties and may soften or deteriorate some plastics and elastomers (particularly vinyl-based resins, neoprene and natural rubbers) upon contact.
Health Hazard
Dimethyl methylphosphonate
(DMMP) administered to male rats is a reproductive
toxicant and carcinogen. Effects in
humans are unknown.
Brandgefahr
Dimethyl methylphosphonate is combustible.
Sicherheitsprofil
Moderately toxic by
intravenous route. Experimental
reproductive effects. Questionable
carcinogen with experimental carcinogenic
data. Mutation data reported. An
experimental nerve gas stimulant. A flame
retardant. When heated to decomposition it
emits toxic fumes of POx
