Investigations on an efficient and environmentally benign poly(oxymethylene) dimethyl ether (OME3-5) fuel synthesis

Autor: Martin Mittelbach, Sigurd Schober, M. Hochegger, Sumea Klokic

Publikováno v: Renewable Energy. 147:2151-2159

Poly(oxymethylene dimethyl ethers) (OMEn, CH3O˗(CH2O)n˗CH3) with the appropriate chain length n = 3–5 are discussed as alternative diesel fuels due to their applicability for direct blending with diesel fuel in slightly modified diesel engines. T

Bias and Imprecision in the Determination of Free Glycerin in Biodiesel: The Unexpected Role of Limitations in Solubility

Autor: Martin Mittelbach, Sigurd Schober, Richard W. Heiden

Publikováno v: Journal of the American Oil Chemists' Society. 94:285-299

Residual free glycerin (FG) is a critical marker of fatty acid methyl ester (biodiesel) fuel quality. Yet, routine determinations by standard methods display excessive imprecision, and the uncertainties undermine confidence in the data. Various degre
