Abstract

V diplomski nalogi smo želeli regenerirati odpadni devterirani kloroform, ki je po uporabi za snemanje NMR spektrov, drugače zavržen. Regeneracije smo se lotili s predposkusi z nedevteriranim kloroformom, kateri so nas usmerjali pri čiščenju realnega vzorca. Uporabili smo več metod ločevanja, in sicer: filtracijo, ekstrakcijo, destilacijo in sušenje. Zaradi podobnih vrelišč smo izvedli frakcionirno destilacijo, za posamične frakcije pa smo izvedli NMR analize. Rezultati, pridobljeni s pomočjo NMR spektroskopije so nam pokazali uspešnost regeneracije, v nekaterih pa je kloroform še vedno vseboval snovi za ločbo katerih bi potrebovali nadaljnje postopke.

Secondary abstract: In the diploma thesis, we tried to regenerate waste deuterated chloroform that is usually discarded after being used for NMR spectroscopy. First we did pre-experiments with nondeuterated chloroform, which directed us when purifying an actual, deuterated sample. There were several methods we used for separation: filtration, extraction, distillation and drying. Due to properties of substances, we used fractional distillation and did NMR analysis for individual fractions. The results obtained by NMR spectroscopy showed us succsessfulness of regeneration and exposed substances that stay in the chloroform and would need further separation procedures.
