PODE can be produced from methylal and formaldehyde or a formaldehyde equivalent such as paraformaldehyde〔(Lithium halide-assisted formation of polyoxymethylene dimethyl ethers from dimethoxymethane and formaldehyde ), Journal of Molecular Catalysis〕 or trioxane. PODE is used as a diesel fuel additive and as a solvent. The average cetane number is 76 and the quality of blended diesel with PODE (blending ratio between diesel and PODE is 85 to 15) is better than ultra-low-sulfur diesel. By comparison, the combustion efficiency can be improved for the blended diesel, the emissions of PM2.5 and CO can be reduced largely, and off-gas pollution can be cut by more than 50%. ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Polyoxymethylene dimethyl ethers」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
