Relationships among ?ash point, carbon residue, viscosity and some impurities in biodiesel after ethanolysis of rapeseed oil

Original language description

Many samples of rapeseed oil ethyl ester were prepared by alkaline-catalyzed transesteri?cation at various conditions (reaction time, temperature, amount of catalyst, the molar ratio of ethanol to oil, the rotations of a disperser and the puri?cation bywater). The concentrations of the key impurities for biodiesel quality (the concentrations of monoglycerides, diglycerides, triglycerides, free glycerol, ethanol, free fatty acids, water) and some qualitative parameters (?ash point, carbon residue, kinematics viscosity at 40 °C) were determined and then the relationships among them were found out. The relationships were characterized by the linear or non-linear statistical models. The found models enable the better understanding of the signi?cance of the qualitative parameters and estimate them from the concentrations of impurities. The temperature dependence was also measured in the case of the viscosity of ethyl ester and used rapeseed oil.
