How To Make Delta 8 THC: CBD to Δ8 THC Step-By-Step

Written by Antonio DeRose

Making delta-8 tetrayhydracannabidiol (D8) is one of those processes that require very specific steps. D8 is a naturally occurring cannabinoid. The downside is that it isn’t produced naturally in very high quantities. For this reason, scientists found a way to convert CBD into D8.

The steps for making D8 from CBD that we’re about to look at are part of a patented process. It  produces high yields and high purity, making it popular among D8 processors and manufacturers.


Step 1

The first step is to start by extracting CBD from high-grade hemp CBD flower or biomass. CBD can be extracted from hemp using your preferred method of extraction. This could be using butane, ethanol, supercritical CO2, or any of the other common extraction solvents, or even solventless extraction methods.


Step 2

Once you have extracted the CBD, you can set it aside. The next step is to mix a Lewis acid in a solvent, like ethanol, or CO2.


Step 3

Once the Lewis acid and solvent mixture is ready, the CBD is then added to the mixture, and then the combined mix is refluxed.


Step 4

After the new mixture is refluxed, it is then diluted with another solvent before it gets poured into cold water where it is mixed and left to separate.


Step 5

Then, after the separation process has been completed, the D8 gets eluted from the final product to be used in D8 products.

Making D8 using this step-by-step process is how a lot of companies are sourcing their D8 for products. Although some of the variables may change, like which extraction methods are used and what solvents extractors use to extract the initial CBD from hemp, the process of converting  CBD into D8 is fairly similar from processor to processor.
