| 1 | Distribution Coefficient of Caprolactam and Methyl Caprolactam Using Benzene or Toluene as Extractants: Experiments and Prediction显示文摘To get high purity caprolactam is a challenging task in the chemical fiber industry. To date, reports on the prediction of the distribution of caprolactam and its derivative chemicals have been few. In this study, the ex-traction of caprolactam with toluene as the extractant and N-methyl caprolactam with benzene and toluene as the extractants has been carried out. By defining new UNIFAC groups and calibrating related interaction parameters, a UNIFAC method was introduced to predict the equilibrium concentration of caprolactam and methyl caprolactam in toluene or benzene extraction processes. The calculated results fit very well with the experimental data. Using the UNIFAC model, the selectivity of extractants can be predicted. | 龚行楚 吕阳成 骆广生 | 2007 | Chinese Journal of Chemical Engineering2007，15，4： | 8 |
| 2 | 三元物系液-液平衡计算的Fsolve算法(英文)显示文摘本文基于MATLAB优化工具箱中的fsolve算法,提出了一种计算三元物系液—液平衡数据的新方法.应用该方法预测了水(1)+醋酸(2)+氯仿(3)物系在298 K,308 K和318 K的液—液平衡数据,并将298K的液—液平衡数据与文献数据进行了比较,它们非常一致.在本论文中,应用UNIFAC液—液平衡模型,采用H_2O,CH_3,COOH和CHCl_3基团相互作用参数计算该物系共轭相中各组分的活度系数,获得了多组结点数据及相的比率.各温度下计算结果显示:各三元液—液相平衡模型约束方程的剩余均接近于零向量,数量级在10^(-4)以下.Other-Tobias关联得到线性相关系数分别是0.9863,0.9939和0.9976.总之,本算法的可靠性,稳定性适用于计算三元液—液相平衡,计算实例所得结果经过检验是正确的. | 彭昌荣 刘期凤 | 2008 | 计算机与应用化学2008，25，6： | 1 |
