Ferrocene Purification Using Sublimation

Sublimation can be used to purify ferrocene, a solid that turns directly from a solid into a gas. This phase change happens without first becoming a liquid. It occurs at temperatures and pressures lower than the compound's triple point.

During sublimation, the solid is heated into the gas phase. ...

Sublimation is the phase transition of a substance from solid into gas without passing through its intermediate liquid phase. It is an important technique used for purification of organic and inorganic solids.

Usually the transition from solid to gaseous state requires passing through its liquid state.

However, reduced pressure and h...
