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. 根據銀杏葉內不同有效成分極性不一樣和相似相溶原理，選用乙二醇二甲醚這一非極性溶劑提取銀杏葉中非極性成分。
Based on this, the thermodynamic equilibria of methanol synthesis reactions using tetraethyleneglycol dimethyl ether and squalane as liquid media were computed respectively. 在此基礎上，分別對以四甘醇二甲醚和角鯊烷為液相介質的反應熱力學平衡進行了計算，結果表明液相介質具有提高甲醇平衡收率的作用。
