The present disclosure relates to a method of decomposing a phenolic by-product, including: a step of feeding and thermally cracking a phenolic by-product stream to and in a decomposition apparatus, recovering an active ingredient from a top discharge stream, and discharging a high-boiling substance through a bottom discharge stream; a step of pressurizing each of a side discharge stream of the decomposition apparatus and a bottom discharge stream of the decomposition apparatus; a step of mixing the pressurized side discharge stream of the decomposition apparatus and the pressurized bottom discharge stream of the decomposition apparatus with each other to form a mixed stream; and a step of passing a part of the mixed stream through a reboiler, circulating the part of the mixed stream to the decomposition apparatus, and discharging a residual mixed stream.

Provided is a method of decomposing phenolic by-products, and more particularly, a method of decomposing phenolic by-products including: supplying a phenolic by-product stream to a decomposition device to perform thermal decomposition; separating an upper discharge stream including effective components and a lower discharge stream including materials having a high boiling point in the decomposition device; supplying the lower discharge stream from the decomposition device, a side discharge stream from the decomposition device, and a process water stream to a mixing device and mixing these streams; and supplying a discharge stream from the mixing device to a layer separation device to separate the discharge stream from the mixing device into an oil phase and an aqueous phase.

Processes for making phenol and xylenes from a phenols-containing feed are described. The processes involve transalkylation of alkylphenols to form phenol and alkylbenzenes. The phenol is separated from the alkylbenzenes, and the alkylbenzenes may be separated into benzene, toluene, xylenes, and heavy alkylbenzene streams. The benzene stream may be recycled to the transalkylation reaction zone. The toluene may be sent to a disproportionation reaction zone, and the product is sent back to the aromatic separation zone. The toluene can also be recycled to the transalkylation zone. The xylenes are separated into a p-xylene stream and a mixed xylene stream comprising m-xylene and o-xylene. The mixed xylene stream is isomerized and the isomerized product is sent back to the aromatic separation zone. The heavy alkylbenzenes are dealkylated and separated, with the aromatic stream being recycled to the aromatic separation zone.

Methods of recovering cannabinoids from cell cultures include methods comprising steps of separating the cell culture at a temperature above the melting point of the cannabinoid to separate a light phase comprising liquid state cannabinoid from a heavy phase; and methods comprising treating the cell culture at a temperature below the melting point of the cannabinoid to separate a light phase from a heavy phase comprising solid state cannabinoid. Other methods include contacting the culture with a water-miscible solvent to form a water-miscible phase and an aqueous phase, separating the two phases and recovering the cannabinoid. Other methods include contacting the culture with a water-immiscible solvent to form a water-immiscible phase and an aqueous phase, separating the two phases, and recovering the cannabinoid. Other methods include washing the inner surface of a fermentation vessel with alkaline solution to recover cannabinoid attached to the vessel surface. Various methods make use of aqueous solvent systems comprising no organic solvent, aqueous solvent systems comprising added water-miscible organic solvent, and dual-phase aqueous/water-immiscible solvent systems.
