Predication of atmospheric VLE for the ternary system dimethyl carbonate-methanol-n-heptane |
| |
Abstract: | The n heptane was chosen as the azeotropic agent for separating the mixture of dimethyl carbonate (DMC) and methanol and the vapor liquid equilibrium (VLE) data of DMC CH3OH,DMC C7H16 and CH3OH C7H16 were determined by experiment The VLE data of the above binary systems, Eos+γ method, Wilson equation and C++ program language were used to calculate the VLE data of the DMC CH3OH C7H16 system under normal pressure These data provides a base of using n heptane as azeotropic agent to separate the mixture of DMC and methanol |

Keywords: | dimethyl carbonate methanol n-heptane vapor-liquid equilibrium calculation |
