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
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.
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]
Turpentine and petroleum distillates such as coal oil and kerosene, were used in folk medicine for abrasions and wounds, as a treatment for lice, and when mixed with animal fat, as a chest rub or inhaler for nasal and throat ailments. [26] [27] Vicks chest rubs still contain turpentine in their formulations, although not as an active ingredient ...
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.
Saturate, Aromatic, Resin and Asphaltene (SARA) is an analysis method that divides crude oil components according to their polarizability and polarity. The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons ( paraffins ).
Ion-exchange resin beads. An ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange, that is also known as an ionex. [1] It is an insoluble matrix (or support structure) normally in the form of small (0.25–1.43 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate.
Mineral oil is used as a brake fluid in some cars, such as Citroën models with hydrodynamic suspension, and bicycle disc brakes. Mineral oil is burned in specialized machines (both manufactured and home-made) to produce a thick white smoke that is then blown into automotive evaporative emissions (EVAP) systems to find leaks.
