The thermal pressure coefficients of methanol, 1-propanol, 1-butanol and 1-decanol have been measured over the temperature range of 25-85℃. A generalized relationship between the thermal pressure coefficient and density for normal alcohols was established, which can be used to predict their internal pressure at various temperature. Some valuable information on the association of normal alcohols and method of estimating degree of association were obtained by homomorph approach.
