| The crude crystals are recrystallized from a mixture of toluene and ligroin by use of decolorizing charcoal. |
| Among other non-hydrophilic organic solvents mentioned above, benzene and ligroin prove to be particularly desirable for practical use. |
| Ligroin is a mixture of saturated hydrocarbons with properties of hexanes. |
| When nothing is known about the mixture being separated, the column is prepared in ligroin or hexane, the least polar of the eluting solvents. |
| Ligroin is a common solvent used in reactions which consist mostly of mixed hexanes. |
| Aluminium oxide, polyvinylchloride and polyethylene were used as solid particles in ligroin and tetralin. |
