Polyoxymethylene dimethyl ethers (PODE or DMMn) are a class of chemical compounds with the molecular formula H3CO(CH2O)nCH3 where n is typically about 3 to 8.
PODE can be produced from methylal and formaldehyde or a formaldehyde equivalent such as paraformaldehyde[1] or trioxane.[2]
PODE is used as a diesel fuel additive[3] and as a solvent.
