Dynamic viscosity analysis
Dynamic viscosity measurements at 40°C of the oxidized linseed biodiesel samples, precipitant and supernatant phases were performed with a Rheometer AR 2000 (TA Instruments), using a cone and plate geometry with a 4 cm cone in steady state flow mode. For each sample, 7 points were acquired in the range shear rate 1–100 s−1, and its average given.
