用流动周期函数法研究了低级脂肪醇对褐煤转化为液体产物的作用。乙醇和异丙醇活性最高。褐煤的转化伴随着液态和固相中脂肪碎片的富集化。液体中芳烃的缩合程度随褐煤转化率的提高而增加，与醇的种类无关。芳香链段取代度和液体数均相对分子质量的大小顺序为甲醇、〉乙醇、〉异丙醇。I.R和1H n.m.r.数据和元素分析表明，褐煤液化过程中液体和固体产物均发生烷基化反应，固体中脂肪碎片的数量与褐煤在乙醇中的转化率呈线性关系。
The action of lower aliphatic alcohols on lignite conversion to liquid products has been studied using flow periodical function. Ethanol and isopropanol were shown to be most active. The lignite conversion is accompanied by enrichment of the aliphatic fragment, both in the liquid and solid phase. The degree of condensing of the aromatic fragments in liquid increases with the enhancement of lignite conversion and does not depend on the alcohol species. Substitution degree of aromatic fragments and the number average molecular weight of liquids decreases in the order methanol 〉 ethanol 〉 isopropanol. I.r and1H n.m.r. data and elemental analysis have shown that alkylation both of liquid and solid products takes place during lignite liquefaction A linear relation between the quantity of aliphatic fragments in solid and the lignite conversion in ethanol is established.
