In this work, densities of two binary mixtures of alkanol (ethanol and 1-propanol) + boldine were measured at temperatures from (313 to 363) K and pressures up to 20 MPa using an Anton Paar vibrating tube densimeter. Each alkanol + boldine system was prepared at five diluted compositions with respect to the alkaloid. These were (x2 = 0.0012, 0.0074, 0.0136, 0.0196, 0.0267) and (x2 = 0.0018, 0.0046, 0.0077, 0.0112, 0.0142) mixed in ethanol and 1-propanol, respectively. Experimental densities were correlated with an empirical 6-parameter equation. Deviations between both sets of data were found to be within 0.04%. Extrapolated densities at atmospheric pressure agree with the literature data. Isobaric expansivity, isothermal compressibility, thermal pressure coefficient and internal pressure were also calculated.
