Abstract:Pri sintezi zdravila se kot povratno topilo uporablja cikloheksan. Sestava cikloheksana iz procesa, namenjenega za regeneracijo, je cca 80% cikloheksana, 19% THF, ostanejo še metanol, toluen in aceton. Pri prvi stopnji regeneracije povratnega cikloheksana dobimo 1000L predtoka in cca 1500-2000L regeneriranega povratnega cikloheksana. Sestava: predtok: cikloheksan, THF, metanol, aceton. (45,15% cikloheksan, 53,07% THF, 0,89% metanol, 0,89% aceton) regeneriran povratni cikloheksan: ( 99% cikloheksana, ostalo THF in nekaj malega toluena) Cilj načrtovanih raziskav je bila eksperimentalna določitev procesnih parametrov, s katerimi bi iz predtoka s pomočjo rektifikacije pridobili še preostali cikloheksan. Topilo bi vračali nazaj v sintezo zdravila kot povratni cikloheksan skupaj s povratnim cikloheksanom iz prve stopnje regeneracije. V sklopu diplomskega dela smo podrobno raziskali sledeče segmente: • Določili smo procesne parametre šaržne rektifikacije predtoka. • Določili smo procesne parametre kontinuirne rektifikacije predtoka. • Na podlagi rezultatov obeh rektifikacij smo preučili možnost za celotno regeneracijo povratnega cikloheksana s pomočjo kontinuirne rektifikacije.

Title:OPTIMIZATION OF CYCLOHEXANE REGENERATION BY RECTIFICATION COLUMN
Abstract:In the synthesis of medicines cyclohexane is used as a solvent. The composition of the cyclohexane outflow from the process intended for the regeneration is about 80% cyclohexane, 19% THF, remaining components of methanol, toluene and acetone. In the first regeneration stage of cyclohexane outflow, 1000L of foward flow and 1500-2000L regenerated backflow is obtained. Composition: Forward flow : cyclohexane, THF, methanol, acetone. (45.15% cyclohexane, 53.07% THF, 0.89% methanol, 0.89% acetone) Regenerated backflow: (99% cyclohexane, rest THF and toluene) The objective of the research was experimental determination of process parameters in order to separate the remaining cycloheksane from the foward flow by rectification. The cycloheksane obtained in this separation stage would be used together with the regenerated backflow from the first stage in the synthesis of medicines again. In the frame of diploma thesis we have examined in detail the following segments : • We have defined the process parameters of the batch rectification, • We have defined the process parameters of continuous flow rectification, • Based on the results of both rectification models we examined the possibility of regenerating the entire backflow cyclohexane through continuous rectification.
Keywords:regeneration, rectification, cycloheksane
