Basics
- Often abbreviated as PODE ‘’’p’’’oly’’’O’’’xymethylene’’’d’’’ymethl’’’e’’’ther, OMEx ( ‘’’O’’’xy’’’m’’’ethyle dimethyl ‘’’e’’’thers where X is the chain length) or more infrequently POMDME
- Polyoxymethylene Dimethyl Ethers are a class of Oligomers (Something in between a compund and a giant chain polymer) related to DME
- They have the advantage of being liquid at STP
- Thus they can be used with more conventional fuel system/blended into Diesel Fuel (in a similar manner to how Biodiesel is currently blended, or how Ethanol and other Alcohol Fuels are blended into Gasoline
- More complex to synthesize than Methanol or DME however
Synthesis
- As Per A 2017 Review in “Applied Catalysis” Titled “ Catalytic synthesis of polyoxymethylene dimethyl ethers (OME): A review
- Formaldehyde -> Trioxane (TRI) or Paraformaldehyde (PF) ->
- Methanol + Formaldehyde (Or Formalin ; need to see if it needs to be Anhydrous ) -> OME1 (aka Dimethoxymethane )
