Process design and enhancement of extraction distillation for separating n-propanol and dimethyl carbonate using imidazolium-based ionic liquids

This study identifies [EMim][AC] as an optimal ionic liquid extractant for separating the n-propanol/dimethyl carbonate azeotrope through a multi-scale approach combining quantum chemistry and molecular dynamics, and demonstrates via Aspen simulation that its heat-integrated extractive distillation process significantly reduces total annual cost and gas emissions compared to conventional DMSO-based methods.

Evaluating the host potential of 9,9’-bifluorenyl-9,9’-diol for anisole and the three methylanisole isomers, and its behaviour in mixed guest solutions

Although 9,9'-bifluorenyl-9,9'-diol (H) demonstrates the ability to enclathrate anisole and its three methylanisole isomers, its inability to selectively separate anisole from mixtures and the prevalence of crystallographic disorder in most complexes limit its utility as a separation agent, with thermal and structural data suggesting a specific preference for 4-methylanisole driven by stable host-guest interactions.

A Universal Size-dependent Law for Photocatalysis in Organic Nanocrystals

This study introduces an Ostwald-ripening-induced strategy to fabricate ultrasmall Y6 organic nanocrystals (4–220 nm), revealing a universal size-dependent law where reducing crystal diameter exponentially enhances exciton dissociation and photocatalytic hydrogen evolution rates, achieving record performance in single-component organic photocatalysts.
