A Sublimation Experiment with Unknowns

Key Points

• The aim is to purify an unknown compound through sublimation and determine its identity using spectroscopy.
• Conducted a micro-scale sublimation process to purify an unknown compound.
• Utilized IR spectroscopy for initial analysis of the compound.
• Employed 1H NMR spectroscopy to further identify the compound and assess purity.
• Involved students in individual data collection and analysis to promote responsibility.
• Successfully purified an unknown compound through sublimation methods.
• Identified compounds using IR and 1H NMR spectroscopic techniques.
• Reported improved student engagement and accountability due to the use of unknown samples.
