Ternary liquid-liquid phase equilibria (LLE) of water and acetone with 1-octanol, 2-octanol, 1-pentanol and isopentanol (3-methyl-1-butanol) at 298, 303 and 308 K are presented. With the exception of water + acetone + 1-octanol at 303 K, these systems have not been previously investigated at these temperatures. The data are successfully correlated using the NRTL model. The UNIFAC predictive model was also tested with the various group parameter databases.

STRUCTURAL STABILITY AND ENERGETICS OF THE PHOSPHORUS MICROCLUSTERS P-2 TO P-10 - AN MNDO CALCULATION
YILMAZ, H (1992-05-25)
The geometries of the low-lying isomers of phosphorus P2 to P10 were calculated using the semiempirical modified neglect of diatomic overlap method. It was found that, in those cases (P2 and P4) where spectroscopic data are available, the bond strengths are overestimated. The binding energies were found to be underestimated in those cases (P2, P3 and P4) where thermodynamically derived values for the gas phase are available. A roof-shaped tetramer is a prominent structural unit in low-lying states of P5, P6...
Residual acrylic monomer content of denture base resins with different fiber systems
KÖROĞLU, AYŞEGÜL; Ozdemir, Tonguc; Pamir, Ahmet Duru; Usanmaz, Ali (2012-07-05)
The conversion of monomer to its polymer may not be complete and residual monomer is left over in the polymeric matrix; this, in turn, affects the properties of the polymeric matrix. In this study, we wanted to compare residual monomer content of the unreinforced conventional heat-polymerized and microwave-polymerized acrylic resins with those of fiber-reinforced ones. High performance liquid chromatography was used for the determination of the residual monomer content. Statistical analysis of the results w...
Liquid-(Solid plus Liquid) Transitions in a Two-Component System of (CH3)CCl3 + CCl4
Yurtseven, Hasan Hamit (2020-02-01)
Liquid-(solid + liquid) transitions are studied in (CH3)CCl3 + CCl4 by using the Landau phenomelogical model. The Gibbs energy is expanded in terms of the orientational disorder (OD) parameters for the transitions of the liquid-(rhombohedral + liquid) and liquid-(face-centered cubic + liquid) in a two component system of (CH3)CCl3 + CCl4. From the Gibbs energy, the phase line equations are derived for the transitions studied and they are fitted to the observed T-X phase diagram of (CH3)CCl3 + CCl4 for the c...
Direct Pyrolysis - Mass Spectrometry Analysis of Thermal Degradation of Thio-Click-Modified Poly(2-oxazoline)
Atilkan, Nurcan; Schlaad, Helmut; NUR, YUSUF; Hacaloğlu, Jale (2014-01-01)
Poly(2‐(3‐butenyl)‐2‐oxazoline)s (PBOX) with glucose‐S‐butyl (Glc) and perfluoroalkyl‐S‐butyl (F) side chains (three samples: Glc/F = 100/0, 0/100, and 88/12) are synthesized by ring‐opening polymerization of 2‐butenyl‐2‐oxazoline and thiol‐ene click photochemistry, and their thermal properties are analyzed by direct‐pyrolysis mass spectrometry. Significant changes in the thermal stability and thermal‐degradation products are observed depending on the structure of the side chain. The thermal degradation of ...
Sorption Efficiency of Chitosan Nanofibers toward Metal Ions at Low Concentrations
Horzum, Nesrin; Boyacı, Ezel; Eroglu, Ahmet E.; Shahwan, Talal; Demir, Mustafa M. (2010-12-01)
Chitosan fibers showing narrow diameter distribution with a mean of 42 nm were produced by electrospinning and utilized for the sorption of Fe(III), Cu(II), Ag(I), and Cd(II) ions from aqueous solutions. The ion concentrations in the supernatant solutions were determined using inductively coupled plasma-mass spectrometry (ICP-MS). The filtration efficiency of the fibers toward these ions was studied by both batch and microcolumn methods. High efficiency in sorption of the metal ions was obtained in the both...
