Volumetric properties of (an organic compound + di-n-butyl ether) atT= 298.15 K

“…Figure 2 shows the data for the three binary systems for which is possible a comparison with data from other authors. It is evident that our data are in good agreement with those of Resa et al (3) for {x(C 4 H 9 ) 2 O + (1 − x)CH 3 COCH 3 }, with those by Kammerer et al (13) for {x(C 4 H 9 ) 2 O + (1 − x)C 4 H 9 OH}, and with the data by Arce et al (1) for…”

“…(DBE) has received particular attention in view of the use of ethers as gasoline additives (1,2) and also of its specific use as a possible entrainer for the extractive distillation of azeotropic mixtures. (3) The solvation properties of DBE are also receiving increasing attention for other reasons.…”

Refractive indices, molar volumes and molar refractions of binary liquid mixtures: concepts and correlationsElectronic supplementary information (ESI) available: Table of data (S1) and figures (S1–S5). See http://www.rsc.org/suppdata/cp/b2/b208765k/Presented in part at the 17th IUPAC Conference on Chemical Thermodynamics, July 2002, Rostok, Germany.

“…The trouble in practice is the high sensitivity of D x R to rounding errors in mole fraction, 15 which results in very scattered values. This problem is overcome when interpolations are avoided 26 by measuring densities and refractive indices at identical concentrations, 27,28,32 but it is clearly obviated when…”

“…Similar confusion has arisen in regard to DR, the deviation of molar refraction R from ideality, as recently noted by Fermeglia and Torriano. 15 Some papers 21,[26][27][28] define it on a mole fraction basis, as…”

Thermophysical Property Measurements and Modeling of (Ether + Alkanol + Hydrocarbon) Mixtures: Binary and Ternary Mixtures (Dibutyl Ether + 1-Butanol + 1-Hexene or + Iso-octane) at 298.15 K

“…These chemicals are utilized without additional purification, with the exception of a precise degassing with an ultrasonication bath to avoid the creation of bubbles. Table shows the experimental (ρ), ( u ), and ( n D ) results for pure components DBE, 1-butanol, 1-hexene, and iso-octane, which are compared to the data presented in refs − and show a significant accord.…”
