  • Is ethanol a promising solvent for soybean oil extraction?
  • The experimental results were briefly compared with hexane, once this is the solvent industrially used, and ethanol, for being a promising solvent for soybean oil extraction, using the methodologies of solvent selection of Hansen and the prediction of ln (IDAC) using the COSMO-SAC theory.
  • How to extract soybean oil from ethyl acetate and hexane?
  • To obtain the maximum yield of soybean oil extraction for ethyl acetate, 1-butanol, and hexane, the Soxhlet extractions were performed, whereas around 5 grams of soya flakes were extracted with 150 mL of each solvent for 4 hours in a Soxhlet apparatus (MA491/6, Marconi, Brazil).
  • Which solvent is used in soybean oil extraction?
  • The solvent selection was performed on ethyl acetate and 1-butanol in comparison with ethanol, a well-studied green solvent, and hexane, a non-renewable and industrially used solvent. The effects of temperature and solvent/solid ratio on the yield of soybean oil extraction were investigated through response surface methodology (RSM).
  • Can ethyl acetate and 1-butanol be used to extract soybean oil?
  • The extraction of soybean oil using ethyl acetate and 1-butanol was investigated. It can be concluded that the response surface methodology could correctly describe the effect of the temperature and solvent/solid ratio on the yield of the extractions.
  • Does ethyl acetate increase the yield of soybean oil extraction?
  • According to Dagostin et al. , the increase in ethyl acetate as a co-solvent in mixtures with ethanol leads to an increase in the yield of soybean oil extraction. The isomers of butanol have been found in the literature as promising solvents for vegetable oil extraction , .
  • Does temperature and solvent/solid ratio affect soybean oil extraction yield?
  • The effects of temperature and solvent/solid ratio on the yield of soybean oil extraction were investigated through response surface methodology (RSM). The RSM obtained satisfactory statistical results, with R adj 2 of 0.9958 for ethyl acetate and 0.9729 for 1-butanol.
