Described is a method of selectively isolating non-rigid structure meroterpenes (for example, cannabidiolic acid) from a complex matrix that may also contain rigid structure meroterpenes (for example, THCa), comprising selectively precipitating the non-rigid structure meroterpenes in the form of a triethylamine salt complex by adding triethylamine; isolating the triethylamine salt complex from the mother liquor; then heating the triethylamine salt complex to vaporize the triethylamine, leaving an isolated neutral non-rigid structure meroterpene. In certain embodiments, the starting product is a cannabis resin that has been solubilized in, for example, d-limonene.

A process for manufacturing Pure Propofol with a purity of more than 99.90% is disclosed, said process comprising dissolving Crude Propofol in a solvent in which it is soluble to form a solution, treating the solution with aqueous alkali to form an aqueous alkali layer and a solvent layer, separating the aqueous alkali layer from the solvent layer using a phase separation technique, distilling off the solvent from the solvent layer, and distilling a residue of the solvent containing Propofol using steam or boiling water in a presence of dilute alkali and antioxidant like metabisulfite, under normal pressure or mild vacuum.

A method for purification and separation of cannabinoids, such as cannabidiol and tetrahydrocannabinol, e.g., from dried hemp and cannabis leaves can use a continuous simulated moving bed process, a batch column chromatography method, or a single column, and a combination of one or more of a sequence of purification steps including: filtration, decolorization, activation or decarboxylation, dewaxing, polishing, and crystallization to separate a cannabinoid from the cannabis plant and to provide various cannabinoid products. The cannabinoid products can be used in various pharmaceutical and nutraceutical applications.

The present inventions relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol. Especially, the present invention relates to the preparation of 3,3,5-trimethylcyclohexylidene bisphenol from 3,3,5-trimethylcyclohexanone and phenol in the presence of a gaseous acidic catalyst. The preparation comprises a first drying step and a second drying step wherein in the second drying step the temperature is increased in comparison to first drying step or in the second drying step the pressure is lowered in comparison to first drying step, or in second drying step both the temperature is increased and the pressure is lowered in comparison to the first drying step (d1).

A process for the treatment of waste water, spent air, and hydrocarbon containing liquid and gaseous streams in the cumene/phenol complex is described. Various effluent streams are combined in appropriate collection vessels, including a spent air knockout drum, a hydrocarbon buffer vessel, a fuel gas knockout drum, a phenolic water vessel, and a non-phenolic water vessel. Streams from these vessels are sent to a thermal oxidation system.

A chloride salt eliminator system and method for removal of chloride salt from glycol circulated through a reboiler in natural gas dehydration, in a continuous process, close to the wellhead. Hot glycol from the reboiler is pumped into a salt eliminator unit having independently replaceable filter elements which trap chloride salts which are not soluble in hot glycol and pass clean glycol for return to the reboiler.

Disclosed herein is a method for obtaining compounds and compositions from plant and fungus materials by thermal treatment, affinity capture, filtration, and release through multi-phasic transitions between gas, solid, and liquid states. The compounds of interest are obtained by manipulating the temperature and pressure of the heating chamber. The compounds in gas phase are passed through an affinity medium which captures the compounds of interest in either solid or liquid phase by exposing the compound of interest to the localized micro-affinity environment of the medium. The compounds are separated from the medium using direct competition with solvent or buffers optimized for the specific chemical properties of compounds.
