A novel chelating resin containing sulfoxide and diethylene glycol, poly{4-vinylbenzyl-[2-2-(hydroxyethyl)ethoxyl]sulfoxide} (PVESO) was synthesized using chloromethylated polystyrene (PS-Cl) as material. Its structure was characterized by elemental analysis, infrared spectra, and scanning electron microscopy (SEM at different temperatures was also investigated. The results showed that the adsorption rate was governed by film diffusion at 208C and 258C, by particle diffusion at 308C and 358C.
Three stilbene-eighteen alkyl quaternary ammonium salts were synthesized through three-step reactions. The physical properties of compounds were characterized by UV and fluorescence emission spectra. The new compounds were applied to cotton fiber as fluorescent brightening agents and their performances were evaluated by measuring the degree of whiteness. The surface tension (γ) and the Critical Micelle Concentration (CMC) of compounds were evaluated. The results showed that the three compounds could greatly reduce the surface tension of aqueous solutions.
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.
