Pressure-composition isotherms are obtained for binary mixtures of carbon dioxide + methyl acrylate systems at (40, 60, 80, 100, and 120) degreesC and pressures to 132 bar and for carbon dioxide + ethyl acrylate systems at (45, 65, 85, 105 and 125) degreesC and pressures up to 136 bar. The solubility of methyl acrylate and ethyl acrylate for the carbon dioxide + methyl acrylate and carbon dioxide + ethyl acrylate systems increases as the temperatures increases at constant pressure. The carbon dioxide + methyl acrylate and carbon dioxide + ethyl acrylate systems have continuous critical mixture curves that exhibit maximums in pressure at temperatures between the critical temperatures of carbon dioxide and methyl acrylate or ethyl acrylate. The carbon dioxide + methyl acrylate and carbon dioxide + ethyl acrylate systems exhibit type I phase behavior, characterized by a continuous critical line from pure carbon dioxide to the second component with a maximum in pressure. The experimental results for the carbon dioxide + methyl acrylate and carbon dioxide + ethyl acrylate systems have been modeled using the Peng-Robinson equation of state. A good fit of the data is obtained with the Peng-Robinson equation using an adjustable parameter.
