它是一个自动化的经验基本状态方程拟合方法,是基于分子模拟数据。在总共400个状态点采样的均匀流体区域的温度在150和700 K之间的压力为550 MPa和密度为17.6 mol·dm-3。在每个状态点,计算六个热力学性质。这些性质是亥姆霍兹能量除以温度相对于温度和密度的倒数的不同偏导数。目前的状态方程本身也是明确的,在这个热力学势方面,因此它允许计算所有静态热力学性质,包括汽液平衡数据,仅通过微分。选择光气作为候选物是因为其工业重要性以及由于其危险性而在文献中相应的实验室测量数据的可用性差。
It is reported on an automatized empirical fundamental equation of state fitting approach that is based on molecular simulation data. In total 400 state points are sampled in the homogeneous fluid region for temperatures between 150 and 700 K up to a pressure of 550 MPa and a density of 17.6 mol·dm–3. At each state point six thermodynamic properties are calculated. These properties are different partial derivatives of the Helmholtz energy divided by the temperature with respect to inverse temperature and density. The present equation of state itself is also explicit in terms of this thermodynamic potential, and it therefore allows for the calculation of all static thermodynamic properties, including vapor–liquid equilibrium data, by differentiation only. Phosgene is chosen as a candidate because of its industrial importance and the poor availability of corresponding laboratory measurement data in the literature due to its hazardous nature.
