Sažetak
Ferulic acid (FA) (4-hydroxy-3-methoxycinnamic acid) is a ubiquitous phenolic compound in plant tissues, therefore, it constitutes a bioactive ingredient of many foods. FA is an abundant dietary antioxidant which may offer beneficial effects against cancer, cardiovascular disease, diabetes and Alzheimer's disease. In this work, we were determined apparent molar volume of FA in water at different temperatures (T) and acid molality (m) from the density data (d) obtained with the help of a vibrating-tube Anton Paar DMA-4500 M densimeter. The limiting partial molar volumes, the partial molar expansivity, the isobaric coefficient of thermal expansion, and the interaction coefficient of FA in water have also been computed. They were qualitatively correlated with the changes in the structure of water when FA is dissolved in it.
