Common, nonspecialized group-contribution and corresponding-state models for the estimation of normal boiling point, critical data, vapor pressure, liquid density, dynamic viscosity, and surface tension are reviewed in view of their application to fatty acid ethyl esters to provide guidelines for practical application of these models in process engineering. As a result, these properties can be estimated in a satisfactory manner when choosing an appropriate model, showing minimum average absolute mean deviations of the normal boiling point below 5 K (3.4 K for saturated and 4.2 K for unsaturated components), those of the critical temperature below 3 K (2.3 K for saturated and 1.2 K for unsaturated components), those of the critical pressure in the region of 50 kPa (54 kPa for saturated and 2.1 kPa for unsaturated components), and minimum relative mean deviations of saturation pressures from 2% around the normal boiling point to 15% at extremely low pressures, those of liquid density below 1%, those of viscosity at a maximum of 7%, and those of surface tension around 2.4%.

估计与生物柴油有关的成分的纯成分性质：脂肪酸乙酯

鉴于其在脂肪酸乙酯中的应用，对普通，非专业的基团贡献和相应状态模型进行了评估，以估算正常沸点，关键数据，蒸气压，液体密度，动态粘度和表面张力，为它们提供了指导。这些模型在过程工程中的实际应用。其结果是，这些特性可以以令人满意的方式进行选择时一个合适的模型，显示出低于5 K（3.4 K中饱和和4.2 K中不饱和组分）的标准沸点的最小平均绝对平均偏差，这些关键的估计温度低于3 K（饱和时为2.3 K，非饱和时为1.2 K），临界压力为50 kPa（饱和时为54 kPa，非饱和时为2.1 kPa），
