  • Which solvent can replace n -hexane in rapeseed oil extraction?
  • In this study, several alternative solvents (ethanol, butanol, isopropanol, d -limonene, α-pinene and p -cymene) have been used to replace n -hexane as a solvent used in the extraction of oil from rapeseeds.
  • Which solvent is used to extract rapeseed oil?
  • It was also interesting to observe that p -cymene, d -limonene and isopropanol were the most effective solvents for oil extraction from the original rapeseed, and p -cymene, isopropanol and n -hexane were more selective. Table 1. Extracted rapeseed oil yields with various solvents. ISO 659-1988.
  • Why is n hexane used in solvent extraction?
  • In addition, it presents a high selectivity to oils and a rather low latent heat of vaporization (330 kJ/kg), which allows easy evaporation, efficient extraction and limited energy cost. The use of n -hexane in solvent extraction outperforms mechanical extraction in terms of oil yield and quality.
  • How is rapeseed oil extracted?
  • The extraction meal is desolventized by desorption and evaporation of hexane through direct and indirect steam injection. The oils are recovered by distillation of miscella, which allows evaporation of volatile solvents by vacuum steam stripping. Fig. 1. Conventional processing procedures for rapeseed oil extraction. Color online.
  • What are the optimal conditions for oil extraction from rapeseed?
  • Above all, the optimal conditions for oil extraction from rapeseed and other seeds have been determined. n -Hexane, which has a relatively low boiling point (69 °C), is the commonly-used petroleum-based solvent for extraction of vegetable oils.
  • Is n-hexane extraction a good option?
  • Although n -hexane extraction is considered as a Best Available Technology Not Entailing Excessive Costs (BATNEEC) by numerous environment regulation authorities, concerns with safety, environment and health have nowadays led to a new hotspot in exploring alternative solvents to hexane in order to reduce its emissions and negative effects.
