摘要:
Disclosed are systems and methods which provide a process stream comprising a gaseous component, capture the gaseous component from the process stream by an ionic liquid solvent of a separator, and recover a captured gaseous component from the ionic liquid solvent in a regenerator. A second gaseous component from the process stream may be captured by the ionic liquid solvent of the separator, and the second gaseous component may be recovered from the ionic liquid solvent in the regenerator. Alternatively, the second gaseous component from the process stream may be uncaptured by the ionic liquid solvent, and the uncaptured second gaseous component may be recovered from a membrane unit.

Methods of producing terephthalic acid are described. The methods involve using a substantially pure p-toluic acid stream. The substantially pure p-toluic acid stream, a solvent comprising an ionic liquid and optionally a carboxylic acid, a bromine source, a catalyst, and an oxidizing agent are contacted to produce a product comprising terephthalic acid.

摘要:
The present invention provides a process for producing cellulose shaped articles in which a) cellulose is at least partly dissolved at a temperature of about 100°C or lower in a dope comprising an ionic liquid and a cosolvent to form a cellulose solution, wherein said cosolvent comprises a polar aprotic component, and b) cellulose shaped articles are cast from the cellulose solution.
摘要:
The present invention relates to a process for dissolving metals in perhalide containing ionic liquids, and to the extraction of metals from mineral ores; the remediation of materials contaminated with heavy, toxic or radioactive metals; and to the removal of heavy and toxic metals from hydrocarbon streams.
摘要:
L'invention concerne un procédé d'obtention sélective d'acide formique par réduction électrochimique directe du dioxyde de carbone dans un milieu aprotique conducteur. La réaction est réalisée en cellule électrochimique compartimentée, séparée par membrane échangeuse d'ions (de cations), permettant d'isoler le compartiment anodique (oxydation) du compartiment cathodique, lieu de la réduction électrochimique du CO 2 en acide formique. Le catholyte est un milieu aprotique conducteur, contenant par exemple un solvant aprotique ou un liquide ionique. L'anolyte est un milieu protique, préférentiellement une solution aqueuse acide.
摘要:
Ionic liquids and cellulose ester compositions and processes for producing ionic liquids and cellulose esters. Cellulose esters can be produced by subjecting a cellulose-ionic liquid solution comprising cellulose, one or more ionic liquids, and one or more co-solvents to esterification to thereby produce an esterified medium comprising a cellulose ester. The cosolvents employed in the present invention can be either miscible or immiscible with the cellulose-ionic liquid solution but can be readily dispersed or soluble in the esterified medium.
摘要:
Method for extracting a target alkaloid from a mixture of species, typically from plant matter, using an ionic liquid as an extracting solvent. The ionic liquid may in particular be an alkanolyl-, alkoxyalkyl- or aminoalkyl-substituted ammonium salt.
