Steam is produced in the boiling by heating distilled water with the hot plate. This steam travels upward into the biomass flask where essential oils and water-soluble plant compounds are removed into the vapor stream.. In this way, the essential oils are condensed.
Attempting to distill these Essential Oils directly from the plant material is generally not feasible. In general, most of the Oils' constituents are high boiling and will decompose under the high heat needed to bring them to a boil. Steam distillation is a much gentler method of achieving the same end.
distinguish three types: water distillation; water and steam distillation; and direct. Destructive distillation means distilling volatile oil in the absence of air.. . Cohobation is a procedure that can only be used during water distillation or water and.
