Why is Ethanol Used for Extraction?

What is Ethanol and Ethanol Extraction?

The ethanol is a commonly used fuel, solvent and disinfectant and is also used to make other compounds. Industrial alcohol contains a small amount of methanol, and medical alcohol is ethanol with a concentration of about 75%. It is commonly used in the preparation of traditional Chinese medicine and tanning agents. It can also be used in the osmosis method. It can also be used in the dipping method, the dissolution method or the dilution method and extraction methods.

The ethanol extraction refers to a kind of method taking ethanol as the solvent to extract and purify materials, which makes use of the solubility of ethanol. It is widely used in chemical experiments, chemical purification, chemical pharmaceutical and the production of TCM medicament.

What is Ethanol Extraction Process?

These four extraction methods can all extract ethanol efficiently. There are several steps in the ethanol extraction process, and they are as follows:

Step One — Soaking

Firstly, the dried plant is soaked by ethanol solvent, so that the target substances can be extracted out of sample materials. In the end of this step, you will get mixtures about ethanol solvent and the target substances.

Step Two — Separating

Now we have gotten the mixtures about ethanol solvent and the target substances, what we need to do in this step is to separate them. The method we usually use is to extract ethanol out, because ethanol is volatile. In the end of this step, you will get ethanol solvent and the target substances separately.

Step Three — Concentrating

We have gotten the pure target substances, and what we need to do for now is to concentrate it, in order to get the target substances with higher concentration and purification. And this is the final step of the ethanol extraction process.

Milling Process

There are four steps of producing ethanol, and they are as follows:

  1. Shatter the plant firstly, which makes ethanol-extraction more convenient for users; Before being shattered, the plant needs to be dried through some kind of drying machines.
  2. Sugar is an important substance in the producing process of ethanol. Sugar can be dissolved from the material.
  3. The producing process of ethanol is quite similar with the producing process of beer and wine. Starch is gradually decomposed into sugar and alcohol under the action of enzymes.
  4. The final step is to get ethanol from the third step concentrated, in order to get ethanol with higher concentration. What’s more, gasoline or another additive will be added into it to prevent the tax.

How does Extraction of Ethanol Work?

  In the process of extraction, ethanol is used as the washing solvent, which is to extract the cannabinoids out of hemp plant. Because ethanol is easy to be separated, it is suitable to be the washing solvent. Ethanol extraction is a very high-efficiency extraction method. Because the cbd oil produced from ethanol extraction has a very high purity, which can up to 99%. During the process, first of all, ethanol extracts the cannabinoids our. And then the mixture of cannabinoids and ethanol will be separated, in order to get the cbd oil with a higher purification.

How is Ethanol Extracted?

  Ethanol is always used as the washing solvent. Therefore, knowing how to extract ethanol out of the mixture is very essential . Because ethanol is supposed to be extracted out to get a solvent with a higher concentration. Ethanol is a heat sensitive substance, so heating the mixture is a good way to extract ethanol.

Is Ethanol Extraction for CBD Safe?

  So many people consider if ethanol extraction is safe. According to studies, ethanol extraction is safer than the other two extraction methods. Ethanol extraction is the safest, most high-efficiency, energy-saving extraction method so far.

Why is Ethanol Used as Solvent for Extraction?

  Ethanol is widely used in the plant extraction field. Because ethanol has a very good solubility, which means it can dissolve almost everything. But Co2 doesn’t have that function. And butane is less safe than ethanol and Co2. Therefore, ethanol is a good choice to be used as solvent for extraction. Ethanol has the advantages that Co2 and other solvents do not have, and that’s the reason ethanol is good for it.

Can you Extract CBD with Alcohol?

  As we all know, ethanol is the main component of alcohol. So some people asks if we can extract CBD with alcohol. Technically, ethanol is the solvent in many extraction method. But a high proof alcohol also can reach the same function that ethanol has, which is to extract CBD. Therefore, we can extract CBD with alcohol.
