Processes for obtaining purified unsaturated macrocyclic compounds

A process of obtaining a purified geometric isomer of an unsaturated macrocyclic compound is disclosed herein. The process is effected by contacting an ion exchange medium comprising silver ions with a mixture comprising at least one geometric isomer of the unsaturated macrocyclic compound, to thereby obtain at least one fraction comprising the purified geometric isomer of the macrocyclic compound. A system configured for performing the process is also disclosed.

Cannabis products modified by removing volatile organic compounds and adding volatile unsaturated hydrocarbons

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.

Purified compositions of polyunsaturated fatty acids, their preparation method and their use
10821090 · 2020-11-03 ·

The present invention refers to new purified compositions of long chain polyunsaturated fatty acids, or their salts or esters, characterized by being essentially free from other usually presentbut structurally differentcomponents, such as furan fatty acids, phytanic and pristanic acids, squalene, and some oligomers, as well as several persistent environmental pollutants, such as polychlorinated dibenzo-dioxins and polychlorinated dibenzo-furans, polychlorinated biphenyls, polybrominated diphenyl-ethers, polycyclic aromatic hydrocarbons, and others, which are also usually present and extremely toxic. The invention also refers to the purification method to obtain said compositions and the use thereof as food, food for special medical use, food and diet supplement, and drug.

PROCESSES FOR PRODUCING 2,5-FURANDICARBOXYLIC ACID AND DERIVATIVES THEREOF AND POLYMERS MADE THEREFROM

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).
