Bubble temperatures at 95.1 kPa at nine liquid compositions, spaced evenly over the entire composition range, were measured for three binary systems-methanol (1) + p-xylene (2), propan-1-ol(l) + p-xylene (2), and butan-1-ol (1) + p-xylene (2)-using a Swietoslawski-type ebulliometer. The composition (x(1)) vs temperature (T) data were found to be well-represented by the Wilson model.
