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(zhì)的反應熱力學(xué)平衡進(jìn)行了計算，結果表明液相介質(zhì)具有提高甲醇平衡收率的作用。
