Hydrocarbon extraction is the most popular extraction method used to strip the cannabinoids, such as tetrahydrocannabinol (THC), and terpenes from cannabis . With hydrocarbon extraction, there are two bottlenecks within the process. First is the vacuum oven space required to purge the residual solvent. The definition of Hydrocarbon Extraction as used in the context of marijuana and cannabis. These extraction processes typically involve butane.
Water, just about the most polar solvent, is repelled by the lipid bilayer, and cannabinoids have no solubility in it. In contrast, extraction of water soluble compounds from other plants think tea or tobacco is easily accomplished using water alone.
The non-polar solvents commonly used in virtually all cannabis extraction methods include hydrocarbons, alcohols and supercritical carbon dioxide. Hydrocarbons, as the name implies, are very non-polar compounds made up of only hydrogen and carbon. Almost all hydrocarbons are manufactured by the petrochemical industry, and are components of natural gas, diesel fuel and gasoline. As you might expect, these compounds are highly flammable: While all hydrocarbons could potentially be used for cannabis extraction, in practice only the lower hydrocarbons such as propane and butane are used.
Why are these highly volatile, extremely flammable solvents employed? Well, they work, and they evaporate very easily, making recovery of the dissolved cannabinoids easy. The lower hydrocarbons are also fairly selective for the non-polar cannabinoids, leaving the colored pigments and chlorophyll behind.
Unfortunately, the properties of lower hydrocarbons that are ideal for cannabis extraction high volatility, low viscosity make them extremely dangerous. There is no way to make these hazardous compounds safe, thus extensive engineering controls MUST be employed to avoid disaster. Even then, operator error, or inadequate SOPs can lead to hazardous conditions. Hydrocarbons are the province of Big Oil.
They have the capital and experience to handle the hazards. Do you need to process a large amount of marijuana flower as soon as possible? The fluid is then separated, leaving only concentrates including hash oil, shatter and budder.
The solvent with the essential oils is then heated up to evaporate off the butane or propane, leaving behind the extract. Ethanol extraction is conducted by soaking raw cannabis in ethanol to pull trichomes into the solvent. The cannabis is then removed; the liquid is filtered and the alcohol purged from the extracted material. Whatever your goals may be, each of the three main types of cannabis extraction has its strengths and its weaknesses — with no hands-down favorite among industry executives.
Marijuana Business Magazine asked experts who make their living extracting cannabinoids to share their preferences as well as the pros and cons of their chosen method.

The materials you need for bubble hash are simple: Making rosin can be even simpler than making bubble hash. For rosin, the only materials needed are cannabis, heat and pressure. For small-scale production, people often use a hair straightener, parchment paper, and gloves for safety to press rosin. For those that have the money or access to a lab, an industrial sanitary press can be used in place of a hair straightener. A press utilizes higher pressure and therefore a lower temperature, which keeps more terpene content in the extract remember: A Thermodynamics Research Laboratory at the University of Illinois at Chicago stated that organic solvents currently on the market can have negative long-term effects.
Why does this matter? Because organic solvents have a wide array of uses including decaffeinating coffee and making pharmaceutical drugs. The less hazardous chemicals we use in these processes, the less exposure humans and animals will have. One solution researchers pose is to use supercritical fluids SCFs instead of common, commercial solvents. In English, SCFs are compounds that behave as both a gas and a liquid, so they diffuse more easily than solvents. Because diffusion happens more efficiently with CO2 and other supercritical fluids, the final product will have more potency.
CO2 oil allows for more high-driving compounds like terpenes to be present in the final product because of the lower volatility of the compound. Patients treating seizure disorders and cancer tend to be drawn to this product because of the potency and purity. For these patients, CO2 oil is more desirable than a distillate because of the terpene content. If it is a decarbed product, it is ready to ingest and you can either dab it or consume it by mouth.
Consuming it with a fatty substance like coconut oil or butter will make the oil have higher bioavailability, meaning it can be absorbed into the body more easily. If you want the high, just dab the oil and the heat will decarb it. Research is still being done to learn more about how terpenes drive your high.
With that being said, when shopping for cannabis, looking only at THC content can be a bad representation of the high. One theory I personally have is that when a plant has lower THC, it is because the THC is being compensated for something else like terpenes.
Adding terpene content back into other extracts creates a more diverse, well-rounded high when compared to just having the isolated THC alone.

In a cannabis extraction, the fats will sit on top of the organic layer and can then be removed.
Which extraction method is best for your cannabis company: CO2? Hydrocarbon ? Ethanol? The answer simply comes down to what your. Light hydrocarbon solvent extraction is by and large the most popular method of cannabis extraction. Some processors prefer this method for a. This refers to an extraction process that utilizes hydrocarbon solvents such as butane, propane and hexane to separate the trichomes from the plant material.
