A method for extracting compounds from botanical material using a condensable gas solvent comprising passing the condensable gas solvent containing the at least one compound extracted from a feedstock through a sonic flow nozzle and introducing the solvent exiting the sonic flow nozzle at a supersonic velocity into a cyclone separator.

Disclosed is a purified dialkyl furan dicarboxylate (DAFD) vapor composition containing at least 99.5 wt. % DAFD; 5-(alkoxycarbonyl) furan-2-carboxylic acid (ACFC) that, if present, is present in an amount of not more than 1000 ppm, alkyl-5-formylfuran-2-carboxylate (AFFC) that, if present, is present in an amount of not more than 1000 ppm, 5-(dialkoxymethyl)furan-2-carboxylic acid (DAFCA) that if present, is present in an amount of not more than 1000 ppm, and alkyl 5-(dialkoxymethyl)furan-2-carboxylate (ADAFC) that if present, is present in an amount of not more than 1000 ppm, in each case based on the weight of the DAFD vapor composition.

Disclosed is an oxidation process to produce a crude carboxylic acid product carboxylic acid product. The process comprises oxidizing a feed stream comprising at least one oxidizable compound to generate a crude carboxylic acid slurry comprising furan-2,5-dicarboxylic acid (FDCA) and compositions thereof. Also disclosed is a process to produce a dry purified carboxylic acid product by utilizing various purification methods on the crude carboxylic acid.

An integrated process is useful for producing 2,5-furandicarboxylic acid (FDCA) and/or a derivative thereof from a six-carbon sugar-containing feed. The process includes a) dehydrating a feed containing a six-carbon sugar unit, in the presence of a bromine source and of a solvent, to generate an oxidation feed that contains at least one of 5-hydroxymethylfurfural (HMF) and/or a derivative or derivatives of HMF in the solvent, together with at least one bromine containing species; b) contacting the oxidation feed from step (a) with a metal catalyst and with an oxygen source under oxidation conditions to produce an oxidation product mixture of at least FDCA and/or a derivative thereof, the solvent, and a residual catalyst: c) purifying and separating the mixture obtained in step (b) to obtain FDCA and/or a derivative thereof and the solvent; and d) recycling at least a portion of the solvent obtained in step (c) to step (a).

Purified and modified Cannabis products and methods for producing the same. The purified Cannabis product comprises substantially no volatile organic compounds while retaining Total Potential cannabinoid content. The modified Cannabis product comprises a purified Cannabis product modified by at least one added volatile unsaturated hydrocarbon. The modified Cannabis product is formed by extracting a volatile organic compound from a Cannabis raw material to form a purified Cannabis product, and then adding the at least one volatile unsaturated hydrocarbon to the purified Cannabis product to form the modified Cannabis product and cause an enhanced user experience during combustion and inhalation of the modified Cannabis product.
