Experimental and theoretical study on physical properties of the systems dimethyl carbonate and diethyl carbonate + pentanol isomers

Abstract

In many industrial applications that involve solvents, the knowledge of both thermodynamics properties and transport properties play an important role in the design, sustainability, and optimization of processes in different fields of study. However, it is a fact that there is a lack of data and predictive models for the develop of future applications.Taking this into account, in this work we studied the physical properties of carbonates and pentanol isomers as well as their mixtures due to the versality of these solvents in many processes. We present measurements of densities (ρ) and excess molar volumes and enthalpies (VmE, HmE) at 298.15 K for the systems dimethyl or diethyl carbonate + pentanol isomers; and specifically for the systems with diethyl carbonate the surface tensions (σ ) and the surface tension deviations (δσ) at 298.15 K and the viscosities (η), dynamic viscosity deviations (Δη), refractive indexes (nD) and the changes in the refractive index (ΔnD) at 298.15 and 308.15 K. Different theoretical models were applied to obtained data for surface tensions and refractive indexes.
