Kinetics of polyurethane formation between glycidyl azide polymer and a triisocyanate
Keskin, S; Özkar, Saim (Wiley, 2001-07-25)
Kinetics of the polyurethane formation between glycidyl azide polymer (GAP) and a polyisocyanate, Desmodur N-100, were studied in the bulk state by using quantitative FTIR spectroscopy. The reaction was followed by monitoring the change in intensity of the absorption band at 2270 cm-l for NCO stretching in the IR spectrum, and was shown to obey second-order kinetics up to 50% conversion. The activation parameters were obtained from the evaluation of kinetic data at different temperatures in the range of 50-...
Kinetics of trona sulfur dioxide reaction
Guldur, C; Dogu, G; Doğu, Timur (2001-01-01)
One of the most efficient methods of desulfurization of flue gases involves the reaction of SO2 with activated soda in a dry system. In this work, reactivities of activated soda produced from trona by direct calcination and by spray drying of trona solution were compared and a reaction mechanism was proposed. Due to the textural variations of the solid during the reaction and due to the increased significance of adsorption of SO2, at low temperatures, a two step reaction behavior was observed. Predictions f...
Kinetics of hydrogen generation from hydrolysis of sodium borohydride on Pt/C catalyst in a flow reactor
Boran, Asli; Erkan, Serdar; Özkar, Saim; Eroglu, Inci (Wiley, 2013-04-01)
Here, we report the results of a kinetic study on the hydrogen generation from the catalytic hydrolysis of sodium borohydride in a differential flow reactor. As catalyst platinum supported on carbon (Pt/C) was used in two forms: either as powder or coated on carbon cloth. For optimization of the system several parameters such as sodium hydroxide concentration, sodium borohydride concentration and the flow rate of the feed solution were varied. It was found that the H2 generation rate increases with an incre...
Kinetics of methyl lactate formation over the ion exchange resin catalysts
Özen, Serap Akbelen; Karakaş, Gürkan; Department of Chemical Engineering (2004)
The recovery of lactic acid from its dilute aqueous solutions is a major problem. The ester of lactic acid, namely, methyl lactate has a wide range of applications. The esterification of an aqueous solution of lactic acid with methanol is a reversible reaction. As excess of amount water is present in the reaction mixture, the conversion is greatly restricted by the chemical reaction equilibrium limitations. In this study the esterification kinetics of lactic acid with methanol both in the absence and presen...
