The thermodynamic properties of 2-ethylhexyl acrylate over the temperature range from T → 0 to 350 K

Abstract

The temperature dependence of the heat capacity = f(T) 2 of 2 ethylhexyl acrylate was studied in an adiabatic vacuum calorimeter over the temperature range 6-350 K. Measurement errors were mainly of 0.2%. Glass formation and vitreous state parameters were determined. An isothermic shell calorimeter with a static bomb was used to measure the energy of combustion of 2 ethylhexyl acrylate. The experimental data were used to calculate the standard thermodynamic functions (T), H°(T)-H°(0), S°(T)-S°(0), and G°(T)-H°(0) of the compound in the vitreous and liquid states over the temperature range from T → 0 to 350 K, the standard enthalpies of combustion Δ c H°, and the thermodynamic characteristics of formation Δ f H°, Δ f S°, and Δ f G° at 298.15 K and p = 0.1 MPa.

Process for 2-Ethylhexyl Acrylate Production Using Reactive Distillation: Design, Control, and Economic Evaluation

“…One can consult the Aspen Plus product and easily evaluate the original sources based on which these parameters are determined. Details on acrylate vapor pressure are given by Stull, heat capacity data is given by Kulagina et al, and density data are given by Rehberg et al One set of binary interaction parameters is used to describe the vapor–liquid, liquid–liquid, and vapor–liquid–liquid equilibrium (VLE, LLE, and VLLE, respectively). Three pairs (water/AA, water/2-EH, and AA/2-EH) out of the six are available in the Aspen databanks.…”
