The suitability of phenyl-based deep eutectic solvents (DESs) as absorbents for toluene absorption was investigated by means thermodynamic modeling and molecular dynamics (MD). models perturbed-chain statistical associating fluid theory (PC-SAFT) conductor-like screening model real (COSMO-RS) were used to predict the vapor–liquid equilibrium DES–toluene systems. PC-SAFT yielded quantitative res...

MODELING AND DATA ANALYSIS OF CONDUCTIVE POLYMER COMPOSITE SENSORS Hua Lei Department of Chemical Engineering Doctor of Philosophy Conductive polymer composite sensors have shown great potential in identifying gaseous analytes. To more thoroughly understand the physical and chemical mechanism of this type of sensors, a model was developed by combining two sub-models: a conductivity model and a ...

In the vapor phase a solvent-free spectroscopic analysis of dye molecules is applicable [1-3]. For some dye vapors laser action was achieved [1-3]. The dye vapor pressure rises approximately exponentially with temperature. Reasonable vapor pressures (p around 100 Pa = 1 mbar) are obtained for many non-ionic dyes in a temperature region between 200 and 400 °C without considerable thermal decompo...

This paper describes laboratory scale experiments examining the impact of microwave irradiation on the Granular Activated Carbon (GAC) exposed to toluene, a common organic vapor frequently released into work environment as well as outdoor. A stream containing 300 ppm toluene was supplied and passed through the granular activated carbon. The saturated adsorbent was placed in a quartz glass r...

In this work, highly hydrophobic carbon sponges with large specific surface area were successfully prepared (denoted as HHCS-1, HHCS-2 and HHCS-3). By simply increasing temperature decreasing heating rate, the sponge showed unique sphere structures at points of each connection. Moreover, structure changes from no obvious fold to fold. HHCS-3 largest 2926.2 m2 g−1 exhibited superior adsorption p...

Toluene is a representative member of a class of inhaled solvents that are voluntarily used by adolescents and adults for their euphorigenic effects. Research into the mechanisms of action of inhaled solvents has lagged behind that of other drugs of abuse despite mounting evidence that these compounds exert profound neurobehavioral and neurotoxicological effects. Results from studies carried ou...

In this study, a series of Ce-modified Co3O4 catalysts were prepared by co-precipitation. The influence Ce/(Ce + Co) ratio on the catalyst microstructure and catalytic oxidation performance toluene systematically investigated. results showed that introduction Ce lead to great changes in structure with smaller crystallite size larger specific surface area catalyst. More importantly, dopant can s...
