Abstract: Disclosed are methods for separating, recovering, and purifying CBGA, CBDVA, THCVA, CBCVA, and CBCA from dewatered and desolventized crude complex extracts or mixtures of metabolites, cannabinoids, and Cannabis phytochemicals. The methods comprise solubilizing the extracts or mixtures of cannabinoids in a selected solvent, adding a selected amine to precipitate a CBGA-amine or CBDVA-amine or THCVA-amine or CBCVA-amine or CBCA-amine salt therefrom, dissolving the recovered amine salt in a selected solvent, and adding a selected antisolvent to recrystallize a purified amine salt therefrom. The recrystallized amine salt may be decarboxylated to form a mixture of CBG or CBDV or THCV or CBCV or CBC and amine. The cannabinoid and amine mixture may be acidified to separate the amine from CBG or CBDV or THCV or CBCV or CBC. The recovered CBG or CBDV or THCV or CBCV or CBC may then be concentrated.

Abstract: The present invention provides a high-purity arylsulfonic acid amine salt vinyl monomer which is an extremely industrially useful arylsulfonic acid monomer with excellent storage stability and amphiphilic solubility in both water and organic solvents, a simple and practical method for producing the same, a polyarylsulfonic acid amine salt which is a polymer thereof, and a method for producing the same. In the arylsulfonic acid amine salt vinyl monomer, a tertiary amine having 2 or 3 different substituents that each have 1 to 7 carbon atoms and also containing at least one or more of tertiary carbon or quaternary carbon or cyclic skeleton in the structure is applied to an amine moiety thereof, and in addition, a polyarylsulfonic acid amine salt having high purity in terms of sulfonation rate and polymerization conversion rate and a polymer thereof are used.

Abstract: Methods for producing mesoporous zeolites are provided. In some embodiments, the method includes mixing a silicon-containing material, an aluminum-containing material, or both, with a quaternary amine and at least one base to produce a zeolite precursor solution. The zeolite precursor solution is combined with nanocellulose to form a zeolite precursor gel, from which volatiles are removed. The zeolite precursor gel is crystallized to produce a crystalline zeolite intermediate. The crystalline zeolite intermediate is calcined to form the mesoporous zeolite. The nanocellulose mesopores template may include cellulose nanocrystals, nanocellulose fibers, or combinations thereof. The quaternary amine may include tetraethylammonium hydroxide, tetraethylamonnium alkoxide, tetrapropylammonium alkoxide, other alkaline materials comprising ammonium, or combinations thereof.
