Combustion energies of esters (ethyl 6-methyl-2-oxo-4-phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate; ethyl 6-methyl-4-(4-methylphenyl)-2-oxo-1,2,3,4tetrahydropyrimidine-5-carboxylate; ethyl 4-(4-methoxyphenyl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5carboxylate and ethyl 4-(6-methoxyphenyl)-6-methyl-2oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate) were experimentally obtained using a bomb calorimetry. According to the experimental data, the enthalpies of combustion and the enthalpies of formation in a solid state were calculated. Derivative analysis was used to investigate the compounds within the temperature range of 483.0-577.5 K. The enthalpies of fusion, vaporization and sublimation were calculated using the results of the differential thermal analysis. According to the obtained data, the enthalpies of formation of the investigated compounds in the gaseous state were calculated. The possibility of using the Benson additive scheme to calculate the enthalpy of formation is demonstrated.

“…It is widely used to produce methyl methacrylate (MMA), an important basic organic chemical material, because it has two functional groups, carbon double bond and a carboxyl group, and can conduct polymerization and esterification reactions. In addition, MAA can also be used as raw materials for synthetic rubber, thermosetting paint, synthetic rubber, fabric treatment agent, etc. − With the continuous attention paid to biomass fuel, a large number of experiments have shown that the chemicals and intermediates produced by biomass fuel can effectively replace some coal-based materials, which not only compound the concept of environment friendly, but also can develop downstream industries for industrialization and commercialization. − One of the fields is to synthesize important vinyl polymers in the industry from biomass raw materials, such as methacrylic acid (MAA) and methyl methacrylate (MMA) …”

The development and research of biomass fuels have been paid more and more attention. The production of methacrylic acid is accompanied by a large amount of water and environmental pollution. Therefore, the separation of methacrylic acid from aqueous solution is of great significance for industrial production and environmental protection. The liquid−liquid equilibrium (LLE) for ternary systems of water + methacrylic acid + alcohol solvents at 303.2 K and 101.3 kPa was investigated. Thermodynamic models (NRTL and UNIQUAC) were used to correlate and regress the experimental data. The root-mean-square deviation (RMSD %) was used to evaluate the deviation between the experimental value and the calculated value, which were 1 and 1, respectively, indicating that the extractants selected in the experiment could well separate methacrylic acid from the aqueous solution, and 1-octanol exhibits better extraction performance. The correlation of LLE data is proven by MATLAB. In addition, the binary interactive parameters of the model regression are verified by MATLAB.

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 %.
