| Acetone-free polish removers contain safer fruit-derived solvents like ethyl acetate and methyl pentane. |
| The pentane molecule, however, has neither hydrogen bonding nor polar groups to be attracted to water molecules. |
| The resulting spark can ignite the Pentane vapour liberated from the expanded polystyrene block by the cutting operation. |
| Ventilation in this area should be supplemented with additional fans and fume hoods to dissipate the Pentane vapours along with the other vapours from cutting. |
| After thawing, the volatile components were extracted three times with 50 ml pentane. |
| The absorbance band is narrowest for 3-methyl indole in pentane. |
