Key words: palm oil, Shea oil, ethanol, sub- and supercritical fluid conditions, transesterification, biodiesel, kinematic viscosity coefficient
The results of an experimental study of the process of obtaining biodiesel fuel by
transesterification of Shea (Karite) and palm oils carried out in ethanol under supercritical
fluid conditions on a batch unit using preliminary ultrasonic emulsification of the reaction
mixture are presented. The studies were carried out in a temperature range of 623—673 K
at a pressure of 30 MPa, a range of «alcohol—oil» molar ratios of 30—42, and a reaction
duration of 30 minutes. Preferred reaction conditions have been established. The results
of an experimental study of the kinematic viscosity of samples of initial oils and the
product of the transesterification reaction The results of an experimental study of the
kinematic viscosity of samples of initial oils and the product of the transesterification
reaction are presented.
