采用作者设计的液液平衡釜，于常压下测定了甲基环己烷（１）－ＤＭＦ（２）二元系（２０．０～４７．９℃）的互溶度数据，以及常压、２０．Ｏ℃和３５．Ｏ℃下甲基环己烷（１）－苯（２）－ＤＭＦ（３）三元系和甲基环己烷（１）－苯（２）－ＤＭＦ（３）－水（４）（ＤＭＦ／Ｈ２Ｏ＝４∶１，ｍａｓｓ比）四元系的ＬＬＥ数据。
Using the liquid-liquid equilibrium autoclave designed by the author, the mutual solubility data of methylcyclohexane (1) -DMF (2) binary system (20.0-47.9 ° C) at normal pressure was measured, 20. O ° C and 35. (1) -benzene (2) -DMF (3) ternary system and methylcyclohexane (1) -benzene (2) -DMF (3) -water / H2O = 4: 1, mass ratio) LLE data of quaternion system.
