Abstract
Combined SPPE-IPPE method is proposed to obtain thermal parameters (thermal effusivity, diffusivity, conductivity and volume specific heat) of saturated (caproic C10 : 0) and monoenoic unsaturated (oleic C18 : 1, cis) fatty acids. The method was also used to investigate temperature behaviour of thermal parameters (around the melting point) for lauric acid (C12 : 0). The combined SPPE-IPPE approach eliminates problems associated with sample's transparency and thickness control.
