Thermophysical Properties of Solutions of Iron(III) Nitrate Nonahydrate in Mixtures of 1-Propanol and Water

Abstract

The simulation of spray flame processes for the production of high quality nanoparticles relies on thermophysical properties of the precursor solutions, for which literature data are scarce. Here, we report experimental thermophysical data of solutions of iron(III) nitrate nonahydrate (INN) in (1-propanol + water) mixed solvents. The specific density, viscosity, thermal conductivity and isobaric heat capacity of the solutions were measured at 101.3 kPa between 288.15 and 333.15 K, solvent compositions ranging from 0.73 mol mol -1 1-propanol to pure water, and INN molalities up to 1.3 mol kg -1 . Empirical correlations of the experimental data are provided.

Thermophysical Properties of Mixtures of 2-Ethylhexanoic Acid and Ethanol

“…The isobaric heat capacity of mixtures of EHA and ethanol decreases almost linearly with the ethanol content and increases with increasing temperature. Hence, as for many mixtures investigated in our previous work, − the excess heat capacity is small.…”

“…The roughly linear relationship between viscosities at different compositions is rather unusual. The systems studied in our previous work − show a strong non-ideality of the mixture viscosity and a more complex model was necessary to describe the data.…”

“…All measurement methods are as in our previous work. − Only the sample composition analysis for the VLE measurements was methodically different as explained below. In the supporting information, a comparison of the experimental results for the density and the viscosity of pure EHA from this work and the literature is presented in Figures S1 and S2.…”

Thermophysical Properties of Mixtures of Titanium(IV) Isopropoxide (TTIP) and 2-Propanol (iPOH)

“…Thermophysical data on the precursor solutions are essential for carrying out such simulations 6,8−11 but are scarce in the literature. In recent publications of our group, we have determined thermophysical properties of precursor solutions for the production of iron oxide nanoparticles 12,13 and of solutions of TTIP in p-xylene. 14 In the present work, the thermophysical properties of mixtures of TTIP with iPOH were determined and correlations of the data were established.…”

“…17−20 Bradley et al 21 carried out microebulliometric measurements, which indicate the formation of TTIP dimers at low temperatures. Vaartstra et al 22 investigated mixtures of iPOH with zirconium(IV) isopropoxide and other metal(IV) isopropoxides that are similar to TTIP by 1 H NMR-, 13 C NMR-, and IR-spectroscopy. They found that in these mixtures, iPOH and alkoxides form associates of the type [iPOH] 2 •[alkoxide] 2 .…”
