Compressed Liquid Densities of Boldine + Ethanol Binary Mixtures At Different Compositions From 313 to 363 K

In this work, densities for binary system alkaloid Boldine [2,9-dihydroxy-1,10-dimethoxyaporphine] (1) + ethanol (2) are reported in the compressed liquid region from 313 to 363 K and pressures up to 20 MPa. Measurements of this system were performed at five diluted compositions of the solid, x(1) = 0.0012, 0.0074, 0.0136, 0.0198 and 0.026 in mole fraction. Experimental densities were obtained using a vibrating tube densimeter and compared with the only literature data reported at atmospheric pressure by extrapolating our results.
