A comparative study on selected physical properties of diesel–ethanol–dodecanol blends

Abstract

The article presents findings of the comparative analyses of the selected physicochemical parameters of diesel fuel and diesel-ethanol blends with the addition of dodecanol, used to stabilise the blend Diesel fuel and the blends were tested for density, flash point, and cold filter plugging point. The physicochemical properties were assessed in seven samples with different proportional volumes of ethanol contained in diesel fuel. Homogeneous blends were produced by adding 5% dodecanol to blends containing between 5% and 30% ethanol. The study was conducted to assess the selected physicochemical properties of diesel-ethanol blends with the addition of dodecanol and to compare the obtained results with the requirement of EN590:2022-08.
