41. Chemical separation methods generally use a solvent such as ethanol, butane or hexane to dissolve the lipophilic desirable resin. 42. Extraction is performed by percolation with a variety of solvents, primarily hexane , which are removed prior to use. 43. Research suggests that the hexane extract of the seeds could be used as a way to control type 2 diabetes. 44. Long-Chain Omega-3 FA's are extracted from Algae mainly by the the famous solvent Hexane . 45. It said tests found that hexane levels in the factory's air were several times over state-set limits. 46. The truck was transporting hexane when it burst into flames, said Carl Mehn of the Chester County Emergency Services Department. 47. This quality makes clean-up with pentane or hexanes trivial, but also easily leads to contamination of reaction mixtures. 48. A common choice of chemical solvent is hexane , which is widely used in the food industry and is relatively inexpensive. 49. In preparative chromatography, concentration of a large volume of hexanes can result in a sample that is appreciably contaminated by alkanes. 50. When " n "-hexane is ingested, it causes nausea, vertigo, neurotoxic and produces a polyneuropathy.
