Related to azeotropes:boiling point,Azeotropic distillation a·ze·o·trope (ə-zē′ə-trōp′, ā′zē-) n. A liquid mixture of two or more substances that boils at a constant characteristic temperature lower or higher than any of its components and that retains the same composition in...
Azeotropic mixture with a low boiling point, the use as a refrigerant, propellant or threshold means for plastic foam.The invention relates to a minimum boiling point azeotrope, used as a refrigerant fluid in the replacement of the current trifluorobromomethane (1301) in the industrial ...
the purpose of production of aromatics products, the reforming reaction product - the general de-pentane containing aromatic oil in 30% to 60% and the remaining non-aromatics. This mixture, aromatic and non aromatic or azeotropic boiling point similar to the phenomenon of the general method of ...
Estimation of the entropy of vaporization at the normal boiling point for azeotropic mixtures containing water, alcohol or acetic acid The entropy of vaporization at the normal boiling point has been estimated for binary and ternary azotropic mixtures containing water, alcohol or acetic ac...

polyamideimides with a given hard block and soft blocks differing in their chemical structure and molar weight. In the second part, the results of systematic pervaporation experiments are discussed in terms of structure–property relationships for the separation of an azeotropic mixture of industrial ...
One of the characteristics of this non-azeotropic mixture is the variable temperature during phase change at constant pressure, due to the temperature glide between the dew and the bubble point. This phenomenon can lead to a better ... M Azzolin,A Berto,S Bortolin,... 被引量: 0发表: 20...

blowing-agent-containing isocyanate semiprepolymer mixture based on a polyhydroxyl compound (A) and an organic polyisocyanate (B), which comprises using the polyhydroxyl compound (A) in combination with a linear, branched or cyclic, saturated or olefinically unsaturated monoalcohol having 1 to 25 ...
To replace the azeotropic mixture of chlorodifluoromethane and of chloropentafluoroethane (CFC 502) in low-temperature refrigeration, the invention proposes to employ a pseudoazeotropic mixture containing, on a mass basis, 1 to 15 % of d... Limin,Chen,Yoshihiro,... - 《Chemistry Letters》 被...
In a process for the preparation of acrolein or acrylic acid or a mixture thereof from propane, the propane is subjected, in a first reaction stage, to a partial dehydrogenation under heterogeneous catalysis to give propene, of the components contained in the product gas mixture formed in the ...
