Combination of Theoretical and Experimental Insights into the Oxygenated Fuel Poly(oxymethylene) Dibutyl Ether from -Butanol and Paraformaldehyde.

Oxygenated fuel has the function of self-supplying oxygen during the combustion process, which can greatly improve emission performance and reduce diesel fuel soot production. In this paper, a novel oxygenated fuel poly(oxymethylene) dibutyl ether (PODBE ) is designed and synthesized through experiments in combination with density functional theory (DFT) calculation. The experimental results show that PODBE has the advantages of high cetane number (73.
