%X The upper critical solution temperatures, UCST , of acetone + alkane (n- C5H12 to n-C17H36) and acetone + hexane isomers have been measured. These results are used to calculate an interaction parameter &#958; by using the van der Waals one-fluid model together with the Guggenheim equation of state. Values of &#958; are compared with those obtained from the gas-liquid critical temperatures. The gas-liquid critical temperatures for the n- alkane + acetone systems were taken from the literature whereas those for the hexane isomers + acetone were measured in this work. The values of &#958; calculated from gas-liquid critical temperatures are slightly greater than those calculated from the UCST as has been observed previously for other systems.
