Hash oil or cannabis oil is an oleoresin obtained by the extraction of cannabis or hashish. [1] It is a cannabis concentrate containing many of its resins and terpenes – in particular, tetrahydrocannabinol (THC), cannabidiol (CBD), and other cannabinoids.
Distillate; Dry sift; Hashish or hash - a cannabis concentrate traditionally made by drying the cannabis plant and beating the dried female plant material over a series of screens and then sifting, collecting, and pressing the particles. Bubble hash - water-purified hashish
Such plants can operate at 23–27 kWh/m 3 (appr. 90 MJ/m 3) of distilled water. [ 5 ] Because the colder salt water entering the process counterflows with the saline waste water/distilled water, relatively little heat energy leaves in the outflow—most of the heat is picked up by the colder saline water flowing toward the heater and the ...
Cannabidiol was studied in 1940 from Minnesota wild hemp [87] and Egyptian Cannabis indica resin. [88] [89] The chemical formula of CBD was proposed from a method for isolating it from wild hemp. [87] Its structure and stereochemistry were determined in 1963. [90]
As the product is formed from the reactants, it is vaporized and removed from the reaction mixture. This technique is an example of a continuous vs. a batch process; advantages include less downtime to charge the reaction vessel with starting material, and less workup. Distillation "over a reactant" could be classified as a reactive distillation.

Continuous distillation, a form of distillation, is an ongoing separation in which a mixture is continuously (without interruption) fed into the process and separated fractions are removed continuously as output streams.
A "full spectrum" analysis considers all the "peaks" within a spectrum. Conversely, selective ion monitoring (SIM) only monitors selected ions associated with a specific substance. This is done on the assumption that at a given retention time, a set of ions is characteristic of a certain compound. This is a fast and efficient analysis ...
Limonene is a relatively stable monoterpene and can be distilled without decomposition, although at elevated temperatures it cracks to form isoprene. [9] It oxidizes easily in moist air to produce carveol, carvone, and limonene oxide. [1] [10] With sulfur, it undergoes dehydrogenation to p-cymene. [11]
