−
−	* <b>[[Short Path Distillation]]:</b> is a widely used method for cannabis distillation. It involves heating the cannabis extract under vacuum to reduce the boiling points of different compounds and separate them based on their volatility. The process utilizes a [[Short Path Distillation]] apparatus consisting of a boiling flask, a distillation head, a condenser, and a collection flask.
−
−	* Other:
−	** <b>Wiped Film Distillation:</b> also known as molecular distillation, is a high-efficiency distillation technique. It involves heating the cannabis extract on a heated surface, while a rotating wiper blade continuously spreads the extract as a thin film. This method is particularly effective for separating compounds with similar boiling points and achieving a high level of purity. The most common pieces of equipment are wiped film short-path molecular stills. In this approach, the feedstock of oil is fed into a jacketed vessel that is often heated with an oil circulating temperature control unit to achieve temperatures up to 343 degrees Celsius, though the typical distillation temperature range is 130-180 degrees Celsius. In these systems, the feed stock is distributed on the evaporation chamber wall with a special wiper. The resulting thin film allows the more volatile terpenes to evaporate through the top of the chamber into their own external collection vessel, while the CBD/THC is collected along a temperature-controlled central condenser unit which is cooler (typically 60-70 degrees Celsius) than the evaporation chamber and serves to attract the cannabinoid vapor. The final step in the process is solvent removal, accomplished in a separate, external cold trap, which is also temperature controlled with a chiller.
−	** <b>Steam Distillation:</b> Steam distillation is a method commonly used for extracting essential oils from plants, including cannabis. It involves passing steam through the cannabis plant material, vaporizing the essential oils and other volatile compounds. The vapor is then condensed and collected, resulting in a distilled product.
−	** <b>Vacuum Distillation:</b> Vacuum distillation utilizes reduced pressure to lower the boiling points of the compounds being distilled. By applying a vacuum, the distillation process can be conducted at lower temperatures, minimizing the degradation of heat-sensitive compounds. Vacuum distillation is often employed in combination with other distillation methods to optimize the process.
−	** <b>Fractional Distillation:</b> is a technique used to separate and collect different fractions of compounds based on their boiling points. It involves using a fractionating column, which provides multiple vaporization-condensation cycles, allowing for repeated separation of different compounds based on their boiling points. This method is useful when distilling complex mixtures of compounds.
−	** <b>Cold Trapping:</b> is a technique used in distillation to collect volatile compounds that are condensed at low temperatures. By cooling the distillate vapor, volatile compounds can be collected separately from the non-volatile components, improving the purity of the final distillate.

−	Decarboxylation is the process of converting the non-intoxicating cannabinoid precursor THCA (tetrahydrocannabinolic acid) into THC (tetrahydrocannabinol), which is the psychoactive compound in cannabis. This process typically occurs through heating. Decarboxylation is often performed around 220 to 245 degrees Fahrenheit (105 to 118 degrees Celsius).

The boiling points of different compounds vary, so by controlling the temperature, the desired compounds can be separated from the plant material.
