Measurement and Prediction of Vapor–Liquid Equilibria in Ternary Systems Containing an Organic Component, Cyclohexylamine, and Cyclohexanol
Journal of Chemical & Engineering Data, 2017Co-Authors: Mandy Klauck, Thomas Hähnel, Sandra Richter, Jürgen Schmelzer, Grit KaliesAbstract:The isothermal vapor–liquid equilibrium data are presented for three ternary systems: octane + cyclohexylamine + cyclohexanol, cyclohexane + cyclohexylamine + cyclohexanol, and toluene + cyclohexylamine + cyclohexanol. The experimental data were determined by the dynamic method in a modified Rock and Sieg circulation still at two different temperatures and reduced pressures. The experimental results were compared with the predictions from both UNIQUAC and NRTL activity coefficient models and the equation of state proposed by Elliott, Suresh, and Donohue (ESD EOS).

Organosilanes in low volatile Organic Component coatings
Progress in Organic Coatings, 1995Co-Authors: Shelby F. Thames, Kamlesh Gopichand PanjnaniAbstract:Abstract Six organosilane dicarboxylic acids were used in the synthesis of conventional semi-drying oil based polyesters. Most of the organosilane modified coatings had appreciably lower viscosity than the non-silane control formulation even though the molecular weights were similar, and the non volatile content was identical. This allows for reductions in volatile Organic Components and thus the formulation of high solids coatings. The organosilane modified coatings possessed improved drying characteristics, impact resistance, flexibility, and hardness without loss in adhesion.

FT-Raman spectroscopy: A positive means of evaluating the impact of whale bone preservation treatment
Vibrational Spectroscopy, 2009Co-Authors: S. Le Blond, E. Guilminot, G. Lemoine, N. Huet, J.y. MevellecAbstract:The degreasing methods currently used for osteological collections are not always completely satisfactory. Numerous natural history museums encounter the problem of grease seeping to the surface of bones. FT-Raman spectroscopy was used to characterise cetacean bones, before and after degreasing treatment, in order to evaluate the efficacy of treatment and the impact thereof on bone constituents. The Raman spectra made it possible to monitor the changes in the main bone constituents: the mineral Component with the apatite band at 960 cm−1, the Organic Component with the collagen amide III band at 1270 cm−1 and fat with the lipid CH2 band at 2850 cm−1. The band associated with lipids decreased and even disappeared with degreasing treatment containing chlorinated solvents. This type of treatment enables fat to be extracted both from the surface and from the bone core; however, it debases the Organic Component of bone by denaturing collagen. Alternative types of treatment (acetone or enzyme baths) were tested over a limited period, which did not enable their true efficacy to be demonstrated. During the alternative treatments, no bone degradation was observed. Only the acetone solution was able to extract fat, though only from the surface.

predicting the relative humidities of liquid liquid phase separation efflorescence and deliquescence of mixed particles of ammonium sulfate Organic material and water using the Organic to sulfate mass ratio of the particle and the oxygen to carbon el
Atmospheric Chemistry and Physics, 2011Co-Authors: Allan K Bertram, S T Martin, Sarah J Hanna, M L Smith, A Bodsworth, Qi Chen, Mikinori Kuwata, A Liu, Yuan You, S R ZornAbstract:Abstract. Individual particles that on a mass basis consist dominantly of the Components ammonium sulfate, oxygenated Organic material, and water are a common class of submicron particles found in today's atmosphere. Here we use (1) the Organic-to-sulfate (org:sulf) mass ratio of the overall particle and (2) the oxygen-to-carbon (O:C) elemental ratio of the Organic Component as input variables in parameterisations that predict the critical relative humidity of several different types of particle phase transitions. Specifically these variables were used to predict the critical relative humidity of liquid-liquid phase separation (SRH), efflorescence (ERH), and deliquescence (DRH). Experiments were conducted by optical microscopy for 11 different oxygenated Organic-ammonium sulfate systems covering the range 0.1

microporous Organic polymers for gas storage and separation applications
Physical Chemistry Chemical Physics, 2013Co-Authors: Ze Chang, Dashuai Zhang, Qiang ChenAbstract:Microporous Organic polymers (MOPs), an emerging class of functional porous materials featured with the pure Organic Component have been widely studied in recent years. These materials have potential uses in areas such as storage, separation, and catalysis. In this Perspective, we focused on the gas storage and separation of MOPs. The targeted design and synthesis of MOPs toward the enhancement of gas capacity and selectivity are discussed. Furthermore, special emphasis is given to the post-synthesis modification of MOPs which have been proved to be effective methods to accurately tune the desired properties.
