Conversion Of CBD To THC
Conversion (chemistry), Conversion of cannabidiol (CBD) to tetrahydrocannabinol (THC) can occur through a ring-closing reaction. This cyclization can be acid-catalyzed or brought about by pyrolysis, heating. Known methods Comparison of phytocannabinoids, Phytocannabinoids exist like precursors to their pharmacologically active counterparts. At least three independent methods have successfully converted CBD to THC. * Despite the CBD and THC having the same molecular weight, multiple analytical methods are able to differentiate them. * "on the recovery of both THC (86.7−90.0%) and CBD (92.3−95.6%). The slightly lower recovery of THC can be explained by the fact that THC is less polar than CBD and more likely to remain in the nonpolar sunflower oil." By heat CBD heated to 175, or 250–300 °C may partially be converted into THC. Even at room temperature, trace amounts of THC can be formed as a contaminant in CBD stored for long periods in the presence of moisture and carbo ...

Conversion (chemistry)
Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering. They are described as ratios of how much of a reactant has reacted (''X'' — conversion, normally between zero and one), how much of a desired product was formed (''Y'' — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (''S'' — selectivity). There are conflicting definitions in the literature for selectivity and yield, so each author's intended definition should be verified. Conversion can be defined for (semi-)batch and continuous reactors and as instantaneous and overall conversion. Assumptions The following assumptions are made: * The following chemical reaction takes place: : \sum_^n \nu_i A_i = \sum_^m \mu_j B_j, where \nu_ and \mu_ are the stoichiometric coefficients. For multiple parallel reactions, the definitions can also be applied, either per reaction or using the limiting react ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
