Abstract

Several kinds of mono- and diesters were prepared by estrification of the corresponding organic acids with 2-ethylhexanol. Some of the synthesized esters were hydroxy-esters. Pressure and temperature dependences of viscosity were measured to determine the flow activation quantities based on Eyring's theory. The effects of hydrogen bonding, chain length, and branching in the molecular structure on activation quantities have been investigated and the results were used for discussion of flow behaviors of these esters.
