According to a study from Pau, France, "This work reports the dynamic viscosity data (a total of 72 points) of a series of primary amines which exhibit small association consisting of pentylamine, hexylamine and heptylamine at four temperatures between (293.15 and 353.15) K (every 20 K). and pressures up to 100 MPa (every 20 MPa) which allows to study the influence of the chain length. A falling body viscometer with an uncertainty of +/- 2% was used to perform these measurements."
"The variations of dynamic viscosity are discussed with respect to their behavior due to chain length. Six different models, most of them with a physical and theoretical background, are ...
