Producing anhydrous ethanol through ethanol dehydration is challenging due to the formation of an ethanol-water azeotrope. Traditional methods use carcinogenic liquid separating agents like benzene to break this azeotrope. This study introduces a modified salt extractive distillation technique using ...

Oznake:
time series analysis;fractal analysis;photothermal lens spectroscopy;fractal dimension;
The present work employs time series analysis, a proven powerful mathematical tool, for investigating the complex molecular dynamics of the thermal lens (TL) system induced by the duty cycle (C) variation. For intensity modulation, TL spectroscopy commonly uses optical choppers. The TL formation inv ...
