  • 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.
  • 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.
  • 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.
  • What chemicals are used in rapeseed extraction?
  • Ethanol, n -hexane, methanol, sulfuric acid, sodium chloride, chloroform, methyl acetate, acetic acid, diethyl ether and potassium chloride were of analytical grade and were supplied by VWR International (Darmstadt, Germany). 2.2. Experimental procedures Rapeseeds were coarsely ground less than 30 min before the extraction.
  • Why does ethyl esters yield less than rapeseed oil?
  • Under low-severity reaction conditions (Fig. 9 a), the ethyl esters yield was 70.2% after 8 h, around 20% lower than the yield of FAEE from rapeseed oil. Several process parameters may have influenced this inferior result, with the microalgal oil purity the main contributing factor.
