“…Remarkably, the presence of DCM promoted the adsorption of EAC by NDA-88 to some extent, probably because the DCM within the resin pores intensied the microporous lling of the EAC. 21 As mentioned before, there were abundant mesopores and micropores in NDA-88, and DCM occupied the resin channel and had no strong interaction with EAC, thus enhancing the adsorption of EAC on NDA-88 by promoting micropore lling of EAC. 22 In the binary steam systems of DCM and MB, an analogous trend can be observed for the same reason as that mentioned above.…”

The adsorption characteristics of dichloromethane (DCM), toluene (MB), and ethyl acetate (EAC) vapors on hypercrosslinked polymeric resins (NDA-88) were studied. It showed that the NDA-88 exhibited promising adsorption and regeneration properties.

“…Porous materials with the pore size comparable to the molecule size have proven to be effi cient in such technological processes as adsorption, heterogeneous catalysis, gas storage, and fabrication of various types of membranes. [1][2][3][4][5][6][7] Microporous polymers are solid substances with large and available surface area (typically of 300-1300 m 2 g -1 according to the gas adsorption method 8 ). In contrast to inorganic porous materials, the specifi c surface area, volume and size of the pores, and the pore size distribution of organic porous polymers could be controlled by modifying the length, rigidity, and spatial orientation of the internode fragments.…”
Homocondensation of 1,3-di(5-acenaphthenyl)but-2-en-1-one obtained by dimerization of 5-acetylacenaphthene leads to 1,3,5-tri(5-acenaphthenyl)benzene. No alternative product, 1,3,5,7-tetra(5-acenaphthenyl)cyclooctatetraene, was formed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
