Propiedades Volumétricas y Viscosimétricas de Soluciones Acuosas Diluidas de 1,4 Pentanodiol a varias Temperaturas

Density and viscosity of dilute aqueous solutions of 1.4 Pentanediol were determined at temperatures between 283 and 308K, in a concentration range between 0 and 0.0060 in mole fraction. A Wood -Brusie type capillary neck pycnometer and an Ubbelohde viscometer were used. The partial molar volume of solute in terms of the solute concentration showed a negative slope for all temperatures, indicating that solute behaves in a hydrophobic way. The relative viscosity values were adjusted to a second order equation to obtain the coefficient B, which is related to the size and shape of the molecule of solute.
