The solubility data of 2,6-dimethylnaphthalene (2,6-DMN) in various solvents are of great significance for the separation and oxidation process. The solubilities of 2,6-DMN in six pure solvents including isopropyl alcohol, n-heptane, cyclohexane, ethyl acetate, n-propyl acetate, and 2,2,4-trimethylpentane and two binary solvent mixtures (formic acid + water and acetic acid + water) were measured by a static analytical method with water content in the binary solvent systems varying from 0 to 0.2 at atmospheric pressure. The λh model and nonrandom two-liquids (NRTL) model were used to correlate these solubility data, and the relevant parameters were regressed by the least-squares method. and there is satisfactory agreement between the experimental results and model prediction derived from the λh model and NRTL model.

2,6-二甲基萘在六种纯溶剂和两种二元体系中的溶解度
2,6-二甲基萘（2,6-DMN）在各种溶剂中的溶解度数据对于分离和氧化过程具有重要意义。2,6-DMN在六种纯溶剂中的溶解度，其中包括异丙醇，正庚烷，环己烷，乙酸乙酯，乙酸正丙酯和2,2,4-三甲基戊烷，以及两种二元溶剂混合物（甲酸+水和乙酸）通过静态分析法测量二元溶剂体系中的水含量在大气压下为0到0.2。该λH模型和非随机二液（NRTL）模型用于关联这些溶解度数据，并通过最小二乘法对相关参数进行回归。由λh模型和NRTL模型得到的实验结果与模型预测结果之间具有令人满意的一致性。
