Synthesis and Application of Polyoxymethylene Dimethyl Ethers

Abstract:

Polyoxymethylene dimethyl ethers (DMM_n) were synthesized in moderate yields by the reaction of methylal and paraformaldehyde catalyzed by solid acid. The pure components of DMM₂, DMM₃, DMM₄, and DMM₅ obtained by rectification were characterized by ¹H NMR and mass spectra. The suitable components for blending into fuel were obtained by distillation separation. Furthermore, the combustion and emission characteristics of a diesel engine fueled with diesel and a blended fuel of DMM_3-5 and diesel were investigated respectively.
