|
| Solvents permitted in the UK for extraction include acetone, hexane, ethyl acetate, ethyl alcohol, and carbon dioxide. |
|
| When nothing is known about the mixture being separated, the column is prepared in ligroin or hexane, the least polar of the eluting solvents. |
|
| The residue was redissolved in 0.5 ml of hexane and analysed by gas-liquid chromatography. |
|
| The hexane extract was evaporated, redissolved in chloroform and passed through a short silica gel column. |
|
| In summary, the sample was denatured with aqueous ammonium sulfate and ethanol and was extracted with hexane. |
|
| The mixture also may contain other hydrocarbons, such as propane, butane, pentane, and hexane. |
|
| Immediately wash with methanol, followed by nitrogen and then wash with hexane followed by more nitrogen. |
|
| The coffee grounds are dried overnight and common chemical solvents, such as hexane, ether and dichloromethane, are added to dissolve the oils. |
|
| Another goal is to find a substitute for the solvent hexane, a GHG contributor, which is currently used for canola oil production. |
|
| Specific petrochemicals implicated in one study included benzene, toluene, styrene, hexane, carbon tetrachloride, chloroform, methanol, and vinyl chloride. |
|
| The tissue was homogenized in a mixture of acetone and hexane. |

|
| The organic solvents such as methyl ethyl ketone, hexane, heptane, octane, and nonane of AR grade were distilled before use. |
|
|
|
| Only the following solvents may be used in the extraction: ethylacetate, acetone, carbon dioxide, dichloromethane, n-butanol, methanol, ethanol, hexane. |
|
| Among the pollutants emitted are ethylene glycol monobutyl ether and other glycol ethers, xylenes and hexane. |
|
| The phenolic compounds were eluted with 100 ml of methanol, and the collected fraction was mixed with 40 ml of hexane in a separatory funnel. |
|
| Chronic Effects: Chronic inhalation of hexane may cause numbness or a burning, prickling, tickling, or tingling sensation in the feet, toes, hands, or fingers. |
|
| Typically, to extract the oil, dried and flaked soybeans are immersed in hexane, a volatile organic compound commonly used as an industrial solvent. |
|
| Glassware should be rinsed with hexane and air-dried. |
|
| The solvent may be a hydrocarbon solvent, such as hexane, propane, isobutene, or cycloalkane. |
|
| The hexane is recovered within the system and reused. |
|
| It was also not clear if hexane extractables might exceed safe limits. |
|
| The oil processing involves also the solvent use such as hexane. |
|
