Dimethylmethylphosphonate, often abbreviated as DMMP, is a chemical compound selected from the group of phosphonates. It is a toxic, colorless and slightly flammable liquid.
Production and representation
The production of DMMP is possible, for example, starting from trimethyl phosphite in an Arbuzov reaction with a methyl halide.
Properties
DMMP is a colorless, flammable liquid with a characteristic odor difficult. Your flash point is 69 ° C.
Use
Use is especially dimethyl methylphosphonate as a flame retardant, and as a fuel additive. In organic synthesis chemistry is used for the preparation of highly reactive ylide.
The connection is, among other things, the starting material for the production of the chemical warfare agent sarin and nerve agent.
El Al Flight 1862
A certain amount of media coverage gained DMMP by the fact that it became known after the crash of El Al flight 1862 on 4 October 1992 Amsterdam only after several years that even 240 kg DMMP were aboard the plane.
