The Enthalpy of Mixing of the Laurylmethacrylate with Some Organic Solvents

Abstract

Abstract. The enthalpy of mixing for the binary systems of the laurylmethacrylate with hexane, benzene, 1,2-diclorethane and acetic acid have been measured as a function of their concentration, the temperature of 293 K and at the atmospheric pressure, by the calorimetric methods. The concentration dependences of the enthalpies of mixing were correlated by polynomials. For the system acetic acid-laurylmethacrylate the enthalpies of mixing were positive for all concentrations, while for other systems the enthalpies of mixing takes were positive only when the solvent concentration was greater than 25 mol %.

Thermodynamic properties of solubility of 2-methyl-5-arylfuran-3-carboxylic acids in organic solvents

“…Here it is impossible to determine the enthalpies of dissolution using calorimetry as it was done in [14][15][16], because investigated compounds have very low dissolution. That is why we used gravimetry, the same as in [17,18].…”

Method for Obtaining Isothermal Diagrams of the Liquid - Vapor Equilibrium for the System as Dimethyl Zinc - Dimethyl Telluride

“…Thermodynamic characteristics of solutions are important parameters, both for the theoretical explanation of the features of the solution components interaction and for practical application in the processes of production and purification of substances. These characteristics can be obtained by direct measurement of necessary parameters such as mixing enthalpy, 1,2 and excess volumes 3 or calculated on the basis of liquid-vapor equilibrium data using the Duhem-Margules equation or local composition models. [4][5][6] This work is a continuation of a series of works on the study of liquid-vapor equilibrium in binary organometallic systems.…”
