Effect of cosolvent concentration on phase behavior for the poly(isodecyl acrylate) in supercritical carbon dioxide, propane, propylene, butane, 1-butene and dimethyl ether

초록

High pressure phase behavior data of mixtures of poly(isodecyl acrylate) [P(IDA)] in supercritical carbon dioxide, dimethyl ether (DME), propane, propylene, butane and 1-butene have been studied. The phase behaviors for these binary and ternary systems are shown for temperatures below ca. 200 degrees C and pressures up to ca. 1920 bar. The location of the P(IDA)+CO2 cloud-point curve shifts to lower temperatures and pressures when isodecyl acrylate (IDA) or DME is added to the P(IDA)+CO2 solution. High pressure phase behaviors for IDA in supercritical carbon dioxide were also performed for temperature ranging from 40-120 degrees C and pressures from 38-217 bar. The experimental results in this work are modeled using the Peng-Robinson equation of state.
