[303836] Ultrasonic characterisation of soybean biodiesel produced from different molar ratios
Autores: Pâmella de Assunção Oliveira, Raphaela de Melo Baesso, Rodrigo Pereira Barretto Costa-Félix
Resumo: The ultrasonic characterisation of soybean biodiesel produced from different alcohols and molar ratios was performed at 1 MHz. The measurement of the speed of sound of the biodiesel samples was performed using the pulse-echo technique. It was possible to observe that samples of biodiesel produced from different alcohols under the same molar ratio present a nonequivalent speed of sound. Samples produced at a molar ratio of 6:1 have the lowest speed of sound. The ultrasound could differentiate the biodiesel samples evaluated through the speed of sound parameter.
