The advantage of steam distillation is that the plant material can be recovered after oil extraction for solvent extraction for the isolation of other non volatile compounds whereas in hydrodistillation the plant material is continuously boiled and not possible to recover.

What is Hydrodistillation extraction?
Hydrodistillation is a traditional method for the extraction of bioactive compounds from plants. In this method, plant materials are packed in a still compartment then water is added in sufficient amount and brought to a boil. ... The vapor mixture of water and oil is condensed by indirect cooling with water.
Is steam distilled the same as distilled?
Distillation is a process used to separate liquids in a mixture based on their relative boiling points. ... Distillation is a physical process rather than a chemical one. Steam distillation is a special type of distillation used in temperature-sensitive applications.
Why is steam distillation used with limonene instead of a simple distillation?
Steam distillation is a separation process used to purify or separate water insoluble, temperature-sensitive material. Limonene is an essential oil made up of two isoprene units. It is damaged at higher temperature, so steam distillation is carried out for the extraction of limonene instead of simple distillation.
What are the advantages of using steam distillation in extracting limonene?
Limonene is a high-boiling liquid (bp763 = 175.5-176 °C) which decomposes under the high heat needed to bring it to a boil. Steam distillation is a much gentler way to obtain essential oils, as it allows the distillation of co-mixture of oil and water at a boiling point less than 100 °C.
What is the principle of steam distillation?
The principle of the steam distillation method is that, when the heating of a mixture of two or more immiscible liquids happens, the vapour pressure exerted by the system will be increased. This happens because the sum of the vapor pressures of all the components of the mixture is now combined.
What is the best method to extract essential oils from a plant?
Distillation. Steam distillation is the most popular method to extract essential oils. During this process the botanicals are placed into a still and pressurized steam is forced through the plant material--imagine using a steaming basket on your stove.
What are the disadvantages of steam distillation?
Disadvantages: More time consuming due to due to the low pressure of rising steam. Water on the substance to be distilled causes it to vaporize in delayed time [10].
What can I use instead of distilled water?
4 Substitutes for Distilled Water
- Mineral Water. The first alternative to distilled water is mineral water. ...
- Spring Water. Then, you'll find spring water. ...
- Deionized Water. Also known as demineralized water, this type of H2O has not a single ion of minerals. ...
- Osmosis Purified Water.
Why is steam distillation better than simple distillation?
The advantage of steam distillation over simple distillation is that the lower boiling point reduces decomposition of temperature-sensitive compounds. Steam distillation is useful for the purification of organic compounds, although vacuum distillation is more common. When organics are distilled, the vapor is condensed.
Can steam distillation of ethanol be done?
8)Can steam distillation of ethanol be done using a mixture of ethanol and water? Why or Why not? -No, ethanol cannot be steam distilled with water because it is soluble in water.
What are the advantages of simple distillation?
Simple distillation Fractional distillation Advantages simpler setup than fractional faster distillation times consumes less energy than fractional distillation much better separation between liquids than simple distillation can more readily purify complex mixtures than simple distillation Disadvantages ...
What are the applications of steam distillation?
The most common use of steam distillation is the extraction of natural products from plant materials. This is the main industrial method for obtaining plant essential oils, used in fragrances and personal hygiene products.
