Abstract

The experimental data of viscosity of 22 fatty acid methyl esters and 16 fatty acid ethyl esters are collected from literatures

the free-volume theory based viscosity model of these esters is established and the coefficients in the model are obtained. Investigation shows that the coefficients in the model exhibit regular trends along with the molecular weight of the esters. The relationship between the coefficients and the molecular weight is obtained

and the predictive viscosity values using the relationship are compared with the literature data. Results show that the maximum relative deviation between the calculated viscosity values and those from literatures is lower than 5.5% for fatty acid methyl esters(except for C 20:1 and C 22:1)and 4.0% for fatty acid ethyl esters(except for C 18:1 and C 18:2). For these 38 esters

the overall average relative deviation is less than 1%

indicating that this predictive model could meet the requirements of practical engineering.
