What is Distilland?
The liquid mixture subjected to distillation from which a component is being separated. It is the starting material placed in the distillation flask. The distilland contains the less volatile components that remain after the more volatile fraction has distilled over.

In analytical and preparative distillation, monitoring the distilland composition helps determine when collection of a fraction is complete and when to discard fore-runs or residues. In essential oil steam distillation, the aqueous distilland is discarded after the oil distillate is collected.
The distilland in the flask can become concentrated in less volatile, more hazardous components (e.g., high boiling point solvents or residual reactive compounds). Never let the distilland flask go to dryness unless specifically intended, as concentrated residues may be explosive (e.g., peroxide con…
