摘　　要：利用特制的双循环型汽液平衡釜代替一般的沸点计，对液相溶质的摩尔分数ｘ２和沸点差Δｔ进行了测定，并用回归法求得１，４－丁二醇在溶剂水。The boiling point curves of dilute 1,4 butanediol (BD) in both tetrahydrofuran (THF) and water are determined with a special circulation still instead of common ebulliometer. The activity coefficients at infinite dilution(r) of BD in solvents THF and water are obtained by a proposed correlation method.
