Hexane (C6H14) is a hydrocarbon extracted from crude oil. In fact, hexane is similar to the gasoline we put in our cars; it’s just a slightly lighter molecule made of six carbon chains—compared to octane’s eight. In its pure form, hexane is a colorless solvent that evaporates easily and dissolves only slightly in water.

In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.

Oilseeds are crucial for the nutritional security of the global population. The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n-hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a ...

- What is hexane extraction?
- Hexane extraction is especially utilized to produce soybean oil, which is the most consumed vegetable oil in the U.S. [ 30 ]. However, hexane is explosive, making it unsafe for workers in food-processing plants. In addition, it is both a neurological toxin and a hazardous air pollutant and can cause environmental pollution [ 31 ].
- Is n hexane a good solvent for oil extraction?
- The solid-liquid extraction is a general, simple and effective method of extracting oil for biodiesel production ( Forson et al., 2004 ). Moreover, n-hexane is an effective solvent for oil extraction due to its non-polar nature ( Kuk and Hron Sr, 1998 ).
- Is hexane better than ethanol for soybean oil extraction?
- When comparing the use of hexane vs. ethanol during the soybean oil extraction process, the net present value (the economic metric representing cash flow) was 10.2% higher for hexane extraction; however, the global warming potential for ethanol extraction was lower by 10,600 tons of CO 2eq per year [ 89 ].
- How much hexane is lost in oil extraction?
- While most hexane is recovered from the end products, the solvent extraction process results in average hexane losses between 1.5 to 2 liters per ton of seed processed. These losses typically occur as trace amounts in the crude oil and meal or escape through vents, hot water, or other leakage. Why is hexane used in oil extraction?
