Thermodynamics Of Mixtures

Thermodynamic properties: vapour–liquid equilibria, VLE, or excess enthalpies, HE, for a set of 21 ternary mixtures of the type 1-alkanol + n-alkanone + organic solvent are studied in the framework of the DISQUAC group contribution model. This treatment is extended to the binaries involved. The DISQUAC analysis is developed on the basis of binary interactions only, that is, ternary interactions are neglected. Most of the interchange coefficients needed are available in the literature. The average relative standard deviations are 0.026 for pressure in the VLE (12 systems) and 0.098 in the HE (9 systems). The discrepancies observed are briefly discussed. Keywords: 1-alkanols, n-alkanones, group contribution, liquids, ternary systems, thermodyamics.

Processing Properties

New technique has been used to extract of lignin by adding carboxylic acid derivates and organic solvent to precipitate and extract lignin from black liquor (pulp wastewater). Through this new treatment process, new carboxylate which is decomposed to carbondioxide, water and metal oxide at the high temperature was formed. The process of using organic carboxylic acid and organic solvent to precipitate and extract lignin is low-cost and can not cause second pollution. The lignin obtained through this new process is water insoluble and thermoplastic. Its weigh average molecular weight, purity, and glass transition temperature are higher than 2000, 90% and 150°C, respectively. Through the methods of thermoplastic modification, the thermoplastic properties for high purity lignin-based composite materials are improved significantly. Its melt flow ratio, tensile strength and elongation at break are 0.73 g/10 min, 11.8 MPa, and 21%, respectively. Thermoplastic lignin-based composite materials have good processing properties as well as synthetic polymers for extruding, injection molding, and blowing processes. Lignin, as a kind of natural thermoplastic polymers with good processing properties, can be carried out to process for film, foam, and thermoplastic composite.

Triblock Polymers

Dielectric spectroscopy, at room temperature (20°C), is used to study the dielectric response of ternary mixtures of commercial nematic liquid crystal mixtures E7 and E33, an organic solvent N-Methyl-2-Pyrrolidone (NMP) and a triblock polymers in the frequency range from 0.01 Hz to 1 MHz. The results indicate a dielectric relaxation in the hectohertz region. Individually, both E7 and NMP have rather large low frequency conductivities; however, the low frequency (0.01–10 Hz) behavior of the mixtures has no such behavior. We attribute this behavior to an ion getter effect of the triblock polymer surfactant. Optimized ternary mixtures obtain a real dielectric constant near 230, and loss tangent less than 0.05 at frequencies near 10 mHz.
