Equation of state for methyl tert-butyl ether
摘要
Abstract
In this work, the equation of state for methyl tert-butyl ether (MTBE) is developed based on the experimental data in literature using the Helmholtz energy as the fundamental property with independent variables of density and temperature. Overall, the uncertainty of the equation of state is 1.0% in vapor pressure bellow 430 K and increases with temperature due to a lack of experimental data. The uncertainty in density ranges from 0. 1% in the liquid region to 1.0% elsewhere, including the critical and vapor regions. The uncertainties in the properties related to energy (such as heat capacity and sound speed) are estimated to be 0. 5%. In the critical region, the uncertainties are higher for all properties except vapor pressure. The behavior of the equation of state is reasonable within the region of validity and at higher and lower temperatures and pressures.关键词
