High pressure switchable water: an alternative method for separating organic products from water

Abstract

Biomass conversion to organic products is expected to be a core technology for the future sustainable society. Still, published studies show that the energy cost and environmental impact of making...

Amine-free CO2-switchable hydrophilicity solvents and their application in extractions and polymer recycling

“…64 Many alkanolamines are readily available, less expensive, and less harmful than D-230. 67 Fig. 2 The process by which a CO 2 -switchable anionic SHS (ASHS) containing a hydrophobic carboxylic acid can be used to separate hydrophobic components from a mixture also containing hydrophilic and insoluble components.…”

Recent Advances on Direct Functionalization of Indoles in Aqueous Media

“…Therefore, it is an eternal challenge and opportunity for indole and green chemistry to construct organic molecules, including indole compounds in water, investigate their pharmacological profiles, realize industrial production, and further reduce the energy consumption of separations. [159] In summary, since the broad application of indole and its derivatives in organic synthesis, pharmaceutical chemistry, material science, and other fields, exploring a variety of green and efficient indole synthesis and functionalization has continued to be a hot topic. This review will draw sufficient attention from researchers worldwide to the feasibility of functionalizing indole and its derivatives in water and even other complex organic molecules.…”

“…(vi) All organic synthesis should consider its practical value. Therefore, it is an eternal challenge and opportunity for indole and green chemistry to construct organic molecules, including indole compounds in water, investigate their pharmacological profiles, realize industrial production, and further reduce the energy consumption of separations [159] …”

Influence of a CO2-switchable additive on the surface and foaming properties of a cationic non-switchable surfactant

“…Second, screening of different ionogens has been performed in previous studies and TMBDA has always been either the most effective or nearly the most effective ionogen. [14][15][16] It is expected that the protonation of the additive affects surface and foam properties because the protonation increases the ionic strength and makes the solution more hydrophilic compared to solutions containing the unprotonated form of the additive.…”
