dc.description.abstractThe esterification of propionic acid with isobutyl alcohol has been studied in a batch reactor in the presence of Amberlyst 36 and Amberlyst 70 catalysts. Reaction parameters applied in this study are speed of agitation (500-1000 rpm), particle size of catalyst (400-600 µm, 600+ µm), temperature (318- 348 K) and catalyst loading (4-12 g-dry resin/L). A pseudo-homogeneous kinetic model was derived and all thermodynamic and kinetic parameters were calculated. Forward reaction rate constant for Amberlyst 36 and Amberlyst 70 determined as follows: (k1=160171 exp (-56689/RT) (L mol-1 min-1) (k1=293314 exp (-557292/RT) (L mol-1 min-1). In a comparison of the two catalysts used in this study, experimental results showed that Amberlyst 70 is more effective than Amberlyst 36.en_US
dc.description.abstractPropiyonik asidin izobütil alkol ile esterleşme tepkimesi, Amberlyst 36 ve Amberlyst 70 katalizörlerinin varlığında kesikli bir reaktörde çalışılmıştır. Bu çalışmada; karıştırma hızı (500-1000 rpm), katalizör tanecik boyutu (400-600 μm, 600+ μm), sıcaklık (318-348 K) ve katalizör miktarı (4-12 g kuru reçine / L) reaksiyon parametreleridir. Bir yalancı-homojen kinetik model türetilmiş ve tüm termodinamik ve kinetik parametreler hesaplanmıştır. Amberlyst 36 ve Amberlyst 70 için ileri reaksiyon hızı sabiti aşağıdaki gibi belirlenmiştir: (k1=160171 exp (-56689/RT) (L mol-1 min-1) (k1=293314 exp (-557292/RT) (L mol-1 min-1). Bu çalışmada kullanılan iki katalizörün karşılaştırmasında deneysel sonuçlar Amberlyst 70'in Amberlyst 36'dan daha etkili olduğunu göstermiştir.tr_TR
