According to the theory that similarities can be solvable easily in each other,nonpolar ethyl diol dimethyl ether is used to extract nonpolar compounds in ginkgo biloba leaves. 根据银杏叶内不同有效成分极性不一样和相似相溶原理，选用乙二醇二甲醚这一非极性溶剂提取银杏叶中非极性成分。
Based on this, the thermodynamic equilibria of methanol synthesis reactions using tetraethyleneglycol dimethyl ether and squalane as liquid media were computed respectively. 在此基础上，分别对以四甘醇二甲醚和角鲨烷为液相介质的反应热力学平衡进行了计算，结果表明液相介质具有提高甲醇平衡收率的作用。
