1. A method of converting CBD to a tetrahydrocannabinol, comprising the steps of:
obtaining a pure CBD isolate;
cooling said CBD isolate to a first predetermined temperature to prevent degradation thereof;
preparing a mixture of catalyst and food grade oil, wherein said catalyst is present in an amount of 0.0001-0.2000 mole fractions per X moles of said isolate, said mixture is disposed in a container purged with an inert gas and cooled to a second predetermined temperature within at least a temperature degree range of said first predetermined temperature to prevent degradation thereof;
adding the cooled mixture and isolate to a reaction vessel while providing continuous stirring of the mixture therein;
providing a condensing apparatus in sealable communication with said reaction vessel;
submerging said reaction vessel in a thermally predetermined environment to warm to a third predetermined temperature as a function of said food grade oil's thermal transition point;
after a predetermined time of mixing said mixture, said vessel is emerged into ambient room temperature;
quenching said mixture; and
transferring said quenched mixture to a separatory apparatus to provide an emulsion whereby separable layers form containing an organic oil layer material containing Δ8-THC with a purity of at least 85%.
