What is Liquid-Liquid Extraction?

Liquid-Liquid extraction is a more complex process of separating a liquid mixture over the Liquid-Solid process. Another common term for Liquid-Liquid extraction is as solvent extraction process. The process involves taking liquids, mixing them, and being able to separate them when the liquid settles. Often one part is water while the other can be an organic solvent. The process is illustrated below:

THE EXTRACTION PROCESS

The process involves having an immiscible mixture, represented by A+C and B the parts can be transferred and mixed, and separated. It extracts a solute from a two-part solution by being brought together with another non-homogenous solvent where that solute can be dissolved. From this, the liquid mixtures are isolated with the solutes that can be dissolved distribute where necessary.

Solvents Used in Liquid-Liquid Extraction

While in a Liquid-Solid extraction water is the most common solvent used, in Liquid-Liquid extraction Diethyl Ether is most commonly used. Since the process for Liquid-Liquid extraction requires immiscible solvents things like ethanol and acetone should not be used because they mix with water. Therefore, the listed solvents below are recommended for Liquid-Liquid extraction:

  • Hexane
  • Diethyl Ether
  • Dichloromethane
  • Toluene

All are more commonly chosen for the organic solvent used in this extraction process.

Liquid-Liquid Extraction Uses

There are several processes that require Liquid-Liquid extraction and here are some of the most common uses below:

  • Fermentation
  • Pharmaceuticals
  • Fragrances
  • Food Products
  • Agriculture Chemicals

You can refer to our blog about Liquid-Solid extraction to examine that these two types of extraction methods are used in repetitive industries. So, in a way, they go together at times in terms of their common uses and processes within these industries.

Solvent extraction or Liquid-Liquid extraction is a process that relies heavily on the use of proper solvents. If you have more questions or need more information on the solvents for extractions, we have answers contact us here at Ecolink!

Can You Use Acetone for THC Extraction?

/in /by

THC extraction is a process where the THC component of the cannabis plant is extracted to be used in the production of various THC products. While products such as butane or alcohol are sometimes used in this process, you can also use acetone for THC extraction. Like other methods of extraction where a solvent is used to extract THC, you simply soak the cannabis plant in acetone, run the liquid through a coffee strainer, and then allow the acetone to evaporate. The resin that is left behind is THC and should sit for 24 hours after extraction before use. Once the acetone is evaporated, and the byproduct has sat for 24 hours, the THC can now be used as is, or in the production of other THC products.

Why Acetone is a Good Solvent for Extraction

  • Acetone is a naturally occurring, organic, non-toxic solvent that in small amounts is actually not poisonous if consumed. If you are extracting THC to produce products that will be consumed or inhaled, an organic, non-toxic solvent like acetone is a great option for extraction.
  • Acetone evaporates very quickly and has a low boiling point. So whether you purge your solvent in open air through evaporation, or use a hot plate to boil the liquid out, acetone can be used in either adaptation, and get the job done fast.
  • In addition to being organic, non-toxic, and having the ability to purge quickly, acetone is also a very cost effective solvent. Acetone is simply cheaper than butane and other solvents traditionally used in extraction, making acetone a no brainer if you are trying to decide what solvent to use.

Looking for Acetone for THC Extraction?

Not only can you use acetone for THC extraction, but it is organic, fast acting, and a cheaper alternative to butane.
