rotation. However, the maximum values reached by the conversion for the two reactions
described inFigure10areveryclose (89and82%).
5.2.Analysisof theeffectofsystemstirring
If thesameconcentrationofcatalyst isused,wouldthestirringof thesysteminterferewith the
kineticsof the reaction?Theanswer is: Surelyenough!
Firstly, the lowest catalyst concentration, 0.2%KOH,will be analysed. The impact due the
change in rotational speedwill bevariable in those reactions.Table3andFigure11 showthe
results for the reactionswith0.2%catalyst.
FromTable3andFigure11,wenotethat thetworeactionswith0.2%ofcatalystneedthesame
reaction time to reach their maximum conversion, regardless of the rotation applied to the
Figure 10. Variation of (a) TAG concentration, (b) propagation velocity and (c) TAG conversion for the reactionswith
520rpmof rotation.
