General description
Dimethoxymethane (DMM, methylal) is a biodegradable dimethyl acetal. It can be synthesized by acid catalyzed condensation of formaldehyde with methanol. It is amphiphilic in nature with low viscosity, surface tension and boiling point. It is a flammable, highly volatile solvent with good dissolving power. DMM is considered as a potential alternative fuel and fuel additive due to its high oxygen content and its ability to enhance the combustion characteristics of diesel and petrol. Its thermal diffusivity has been determined by photoacoustic method. Analysis of the molecular structure of DMM by electron diffraction technique shows that it has C2 symmetry with a gauche-gauche conformation.
Application
Dimethoxymethane (Formaldehyde dimethyl acetal) may be used in the synthesis of methoxymethyl (MOM) ethers. It may also be used as an external cross-linker to form microporous polymers.

The rotational barrier for a methyl group at the end of an anomeric system is sometimes lower than we might have anticipated. Thus, in the trans-trans conformation of dimethoxymethane, the barrier to methyl rotation is calculated (B3LYP/6-311++G(2d,2p)) to be 2.22
