Study Notes
Methods of Obtaining Volatile Oils
- Water Distillation: used for dried plant materials, produces turpentine oil
- Water and Steam Distillation: used for either dried or fresh plant materials, produces cinnamon oil and clove oil
- Direct Steam Distillation: used for fresh plant materials, produces peppermint oil and spearmint oil
Specialized Methods
- Ecuelle Method: used for removing citrus oils, involves a trough line
- Enfleurage Method: used for flower petals, involves the use of bland fat/fixed oils and alcohol, and a glass plate
Extraction Methods
- Extraction in Perfumery Industry: involves a uniform temperature, but is an expensive method
Destructive Distillation
- Destructive Distillation (Dry Distillation): produces empyreumatic oils, involves heating wood resin without access to air, resulting in decomposition and the production of volatile compounds, leaving behind charcoal
