Excess enthalpies and excess volumes of binary mixtures of hydrofluoroether with alcohols

Molar excess enthalpies of binary mixtures of [tributyl phosphate+{CH3(CH2)nOH (n=0 to 3)}] at 298.15K

“…As the carbon number of the alcohol increases, the excess molar enthalpy also increases. This order is similar to many references for the binary mixture between low molar mass aliphatic alcohols and other polar component [20,[24][25][26][27][28][29][30][31]. It should be pointed out that in general methanol and other aliphatic alcohols have the same thermodynamic behavior (i.e.…”

“…It should be pointed out that in general methanol and other aliphatic alcohols have the same thermodynamic behavior (i.e. the excess molar enthalpies are both negative or both positive) in the binary mixture of aliphatic alcohols with other component [20,[24][25][26][27][28][29][30][31]. Only a little literature reported the difference thermodynamic behavior between methanol and other aliphatic alcohols [31].…”

Excess molar enthalpies and volumes of binary mixtures of nonafluorobutylmethylether with ethylene glycol ethers at T=298.15K

“…For the results of H E m of all systems and that of V E m of EGE1,1-OH system, the value of G was iterated so that the standard deviation, r, becomes the minimum value. For the results of V E m of other systems, G was fixed as zero and in this case equation (2) coincides with the Redlich-Kister equation [10]. The parameters A i and G are given in TABLE 4 The parameters and estimated standard deviations, r of equation (2) Property Partial molar volume at infinite dilution, V 1 m;2 , of EGEn,m-R were estimated from V E m;2 and molar volume of pure EGEn,m-R, V 2 by the relation: …”

“…We have studied excess molar enthalpies and volumes of binary mixtures of nonafluorobutylmethylether, NFBME with alkanes or alcohols at T = 298.15 K [1,2]. The phase separation was found in the mixtures of NFBME with alkane or alcohol, the long chained hydrocarbon group, such as decan or butanol.…”

Excess molar enthalpies and volumes of binary mixtures of nonafluorobutylmethylether with ketones at T=298.15K

“…We have determined excess molar enthalpies, H E m , and volumes, V E m of binary mixtures of FBME with alkanes, alcohols, and ethylene glycol ethers at T = 298.15 K [1][2][3]. We found from the results that all mixtures showed endothermic mixing, and expansion on mixing, resulting in a thermally unstable solution and a repulsive force based on weak intermolecular interaction between dissimilar molecules.…”
