Descrizione generale

Petroleum ether is the petroleum fraction, consisting of C5 and C6 hydrocarbons (Pentanes and hexanes are the major constituents), commonly used as a laboratory solvent due to its low boiling point and non-polar characteristics.

Applicazioni

Petroleum ether can be used as a solvent for extracting:
  • Non-polar compounds from various samples, such as plant materials or organic mixtures.
  • Carotenoids from the marine Thraustochytrium sp. ONC-T18.

A move from 'standard' white spirit (stdWS, 15-20% aromatics) to low-aromatic or dearomatized white spirit (deWS) has been seen, as the latter are considered to carry a smaller risk of health effects. However, data on health risks of deWS on
