抄録

Since used vegetable oils have been heated in the atmosphere at high temperature, they contain dimers and trimmers of triglycerides. Dimers of methylesters are formed by the methylesterification of the dimers of riglycerides. Therefore, the biodiesel fuels produced from the used vegetable oils contain the dimers of methylesters. These materials will affect the properties of biodiesel fuels. In this study, the effects of the concentration of dimers of methylesters on kinetic viscosity of biodiesel fuels are studied.
