The present invention discloses a high-speed counter-current chromatograph unreeled by a gear ring, including an upper disc, a middle disc and a lower disc, wherein an unreeling gear ring coaxial with the middle disc is fixed above the middle disc, the lower disc is driven by a driving shaft to rotate, the unreeling gear ring is fixed, gear teeth of the unreeling gear ring are distributed on the inner ring thereof, multiple groups of gears engaged with the unreeling gear ring are arranged along the circumferential direction of the inner ring of the unreeling gear ring, gears between the adjacent groups are not engaged with each other, each group of gears includes two gears that are engaged with each other, wherein one gear drives a separation column, the other gear drives an unreeling shaft, the separation column is installed on a separation shaft, the upper ends of the unreeling shaft and the separation shaft are connected with the upper disc, and the lower ends are connected with the middle disc; meanwhile, the unreeling shaft and the separation column rotate with the rotating bracket; and after a liquid inlet tube passes through center shafts of the upper disc and the middle disc, infusion tubes of multiple groups of separation columns and unreeling shafts are sequentially connected in series therewith and finally led out from a liquid outlet tube.

The present invention relates to a method for selectively separating propylene carbonate by adding water to reaction products comprising a polyether carbonate polyol and propylene carbonate, which are generated from a polymerization reaction of propylene oxide and carbon dioxide under a double metal cyanide (DMC) catalyst, wherein an economical and effective separation of propylene carbonate can be achieved.

Disclosed is a method for extracting one or more chemical extracts from a plant product. The chemical extracts are purified and extracted by first separating at least a phytochemical bearing part of a plant product from one or more other portions of the plant product. A carrier oil is then heated at a target temperature to be used as the vehicle for extraction and then mixed with the at least a phytochemical bearing part while the target temperature is maintained. The process may be streamlined by having heating and mixing occur in a press device. The mixed carrier oil and the at least a phytochemical bearing part are then passed through the press device to produce an oil mixture. At least a chemical extract may be extracted from the oil mixture, and in some cases may be further purified by evaporation and/or centrifugation.

The present disclosure relates to lignocellulosic biomass processing and refining to produce hemicellulose and cellulose sugars. Methods and systems for refining a lignocellulosic hydrolysate are provided herein.

The disclosure provides methods and compositions for providing shatter formulations taking the form of crystalline polymorphs, where methods of preparation include preparing tetrahydrocannabinol acid (THCA) powder followed by decarboxylating THCA and removal of terpenes.

The present invention relates to a method for the chlorination of a sucrose-6-acylate to produce a 4,1,6-trichloro-4,1,6-trideoxy-galactosucrose-6-acylate wherein said method includes steps of: (i) combining the sucrose-6-acylate with a chlorinating agent in a reaction vehicle comprising a tertiary amide to afford a mixture; (ii) heating said mixture for a heating period in order to provide chlorination of sucrose-6-acylate at the 4, 1 and 6 positions thereof; and (iii) quenching the product stream of (ii) to produce a 4,1,6-trichloro-4,1,6-trideoxy-galactosucrose-6-acylate;
wherein before said quenching, a portion of said tertiary amide is removed by extraction into a solvent in which said tertiary amide is at least partially soluble.
