How You Can Perform Solvent Extraction
Solvent extraction separates a desired substance from a mixture. This separation is done with the aid of a chemical that prevents the other substances from changing and offers various results. This process is used in several industries, science-based and otherwise, and can be done in several ways. Two of the most common methods used to perform this process are:
- Soxhlet
- Bligh and Dyers
Soxhlet: How To Do It
To perform this method:
- Place your grouping of interconnected solid mineral grains into the SOX thimble, then heat your solvent under your reflux.
- Condense, and extract your cleansed solvent. Move your solutes from the extraction chamber into the reservoir.
- Continue this action until the extraction is complete.
Soxhlet: What Chemicals Can You Use?
The chemicals that can be used for this method are:
- Pure Dichloromethane (DCM)
- Mixtures of DCM with Acetone
- Mixtures of DCM with Hexane
- Acetone-Hexane mixtures
It is important to note, that nonpolar chemicals are not enough to perform the extraction. Hence, the combinations of Acetone, and Hexane.
Soxhlet: What It Is Used For
This process is used for:
- Soils
- Sediments
- Plant Tissues
- Animals Tissues
- Other Bioactive Compounds
Bligh And Dyers: How To Do It
The performance of this method is similar to the Folch Method, involving the separation of lipids. It is conducted in two steps:
- Extract the lipids from the homogenized cell suspension with the chemical to ensure fair distribution.
- Then separate the lipids in the solvent’s phase to process them for their various uses.
Bligh And Dyers: What Chemicals Can You Use?
The chemicals that can be used for this method are:
- Chloroform
- Ethyl Acetate
- Methanol
- DCM
- Clycopenthylmethylether
- Methyltetrahydrofuran
Bligh And Dyers: What It Is Used For
The process is used only for lipids.
