Patent EP-3877374-A1 (EP)
Inventor: DURST TONY
IPC: C07D311/80
Filed: 2020-06-12
Abstract: Disclosed are methods for separating, recovering, and purifying tetrahydrocannabinolic acid (THCA) salts from an organic solvent solution comprising a mixture of cannabinoids. The methods comprise solubilizing the mixture of cannabinoids in a selected C5-C7 hydrocarbon solvent, adding thereto a selected amine to thereby precipitate a THCA-amine salt therefrom, dissolving the recovered THCA-amine salt in a selected solvent and then adding thereto a selected antisolvent to thereby recrystallize a purified THCA-amine salt therefrom. The recrystallized THCA-amine salt may be decarboxylated to form a mixture of Δ9-tetrahydrocannabinol (Δ9-THC) and amine. The Δ9-THC amine mixture may be acidified to separate the amine from Δ9-THC. The recovered Δ9-THC may be concentrated to produce a highly purified Δ9-THC. Also disclosed are THCA-amine salts produced with amines selected from groups of diamines, amino alcohols, and tertiary amines.

Abstract: A "cloud-end" architecture-based PPP-RTK enhancement method. First, massive high-precision user terminals around the globe perform PPP, and once the locations thereof converge, space correction information (comprising ionospheric correction numbers, and tropospheric correction numbers) based on the precise locations thereof is generated, and is uploaded to the "cloud" by means of a communication link. Then, in the "cloud", the space correction information from the massive user terminals is uniformly and intelligently processed to generate gridded space correction parameters, and low-orbit satellites are used to broadcast the space correction information to users in corresponding regions. The user terminals use the received correction information to perform PPP again, and upload the space correction information that is based on the precise locations thereof to the "cloud", which achieves PPP-RTK service around the globe by means of the intelligent evolution of the massive user terminals. The problem in which a traditional PPP-RTK service requires that a large number of ground monitoring stations be built, which is extremely costly and cannot achieve wide-area PPP-RTK service around the globe, is solved.
