Vapor Pressures and Thermophysical Properties of Dimethoxymethane, 1,2-Dimethoxyethane, 2-Methoxyethanol, and 2-Ethoxyethanol: Data Reconciliation and Perturbed-Chain Statistical Associating Fluid Theory Modeling

As a continuation of our effort to establish reliable thermodynamic data for important industrial solvents, dimethoxymethane (CAS RN: 109-87-5), 1,2-dimethoxyethane (CAS RN: 110-71-4), 2-methoxyethanol (CAS RN: 109-86-4), and 2ethoxyethanol (CAS RN: 110-80-5) were studied. Vapor pressure was measured by ebulliometry for dimethoxymethane and by static method for 1,2-dimethoxyethane, 2-methoxyethanol, and 2ethoxyethanol. Heat capacities in the liquid phase of all four compounds were measured by Tian−Calvet calorimetry in the temperature interval (262−358) K. In the case of dimethoxymethane and 1,2-dimethoxyethane, this interval was shortened because of their volatility. The thermodynamic properties in the ideal gaseous state were calculated using the methods of statistical thermodynamics based on calculated fundamental vibrational frequencies and molecular structure data. Calculated ideal-gas heat capacities and experimental data on vapor pressures, liquid phase heat capacities, and vaporization enthalpies were treated simultaneously to obtain a consistent thermodynamic description.Comparisons with literature values are shown for all measured and derived properties. Furthermore, the developed recommended data were used to identify new molecular parameters for the studied solvents within the PC-SAFT (perturbed-chain statistical associating fluid theory) equation of state and to compare their performance with those published in earlier papers; improved performance of the new parameters was achieved.

An additive is a substance, which when incorporated into polymer materials might lead at improvements on the electrical, thermal or mechanical properties of finished products in dependence of their applications, such as automotive, electronics, packaging and consumer goods. This study is based on the idea of using inorganic agents to change the basic properties of an epoxy resin. The well-known plasticizer 1-methyl-2-pyrrolidinone (NMP) was used to solve the inorganic agents and the mixture of obtained solutions was added, in certain amounts, into the epoxy resin prior the hardener of the epoxy system. The idea is to test the hypothesis of forming of ceramic nanostructures into the polymer structure based on local chemical interaction between solved inorganic compounds in certain conditions. The present paper concerns with the effect of changes on the mechanical properties of the epoxy resin.
