  2. Dry distillation - Wikipedia

    en.wikipedia.org/wiki/Dry_distillation

    Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids). The method may involve pyrolysis or thermolysis, or it may not (for instance, a simple mixture of ice and glass could be separated without breaking any chemical bonds, but organic matter contains a greater diversity of molecules, some of which are likely to break).

    en.wikipedia.org/wiki/Soxhlet_extractor

    After many cycles the desired compound is concentrated in the distillation flask. The advantage of this system is that instead of many portions of warm solvent being passed through the sample, just one batch of solvent is recycled. After extraction the solvent is removed, typically by means of a rotary evaporator, yielding the extracted ...

    en.wikipedia.org/wiki/Kugelrohr

    "Short path" refers to the short distance that the vapors of the distillate need to travel, which helps reduce loss and speed up collection of the distillate.This type of distillation is generally performed under vacuum to prevent the compound from charring due to atmospheric oxygen, as well as to allow the distillation to proceed at a lower temperature.

  5. Distillation - Wikipedia

    en.wikipedia.org/wiki/Distillation

    Dry distillation (thermolysis and pyrolysis) is the heating of solid materials to produce gases that condense either into fluid products or into solid products. The term dry distillation includes the separation processes of destructive distillation and of chemical cracking, breaking down large hydrocarbon molecules into smaller hydrocarbon ...

  6. Cannabis concentrate - Wikipedia

    en.wikipedia.org/wiki/Cannabis_concentrate

    Cannabis concentrate, also called marijuana concentrate, marijuana extract, or cannabis extract, is a tetrahydrocannabinol (THC) and/or cannabidiol (CBD) concentrated mass. Cannabis concentrates contain high THC levels that range from 40% to over 90%, [ 1 ] [ 2 ] stronger in THC content than high-grade marijuana, which normally measures around ...

  7. Coking factory - Wikipedia

    en.wikipedia.org/wiki/Coking_factory

    A coking factory or a coking plant is where coke and manufactured gas are synthesized from coal using a dry distillation process. The volatile components of the pyrolyzed coal, released by heating to a temperature of between 900°C and 1,400 °C, are generally drawn off and recovered. There are also coking plants where the released components ...
