摘要：

The dynamic viscosity eta and the density rho of the associative ternary mixture water + diacetone alcohol + 2-propanol have been measured as a function of temperature T (303.15, 323.15, and 343.15 K) and pressure P (less than or equal to 100 MPa). The experimental results correspond to 698 values of eta and rho. With reference to the 54 Values previously published on pure substances and 486 values for three corresponding binaries, the system is globally described by 1188 experimental values for various values of P, T and composition. The results for eta are discussed in terms of excess activation energy of viscous flow.
