Thiol-functionalized PIM-1 for removal and sensing for mercury (II)

Polymers of intrinsic microporosity (PIMs) are a class of microporous polymers with rigid and contorted molecular structures. The special structures lead to incomplete space occupation, and the pores of PIMs originate from the formed void. In this work, we made attempts to expand the applications of PIMs to the aspect of heavy metal removal. First, PIM-1 was synthesized using tetrafluoroterephthalonitrile (TFTPN) and 5,5′,6,6′-tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) as precursors. The primary PIM-1 was quite hydrophobic, and thus could not be evenly dispersed in water, resulting in low adsorption capacity for mercury ions (Hg2+). A conversion of nitrile group in PIM-1 to thiol group was then carried out by two steps, namely carboxylation and introduction of thiol groups. The carboxylation made the polymers more active, and the final thiol-functionalization provided the polymers with hydrophilicity and affinity for Hg2+. The thiolethyl modified PIM-1 (assigned as PIM-G) and thiophenyl modified (assigned as PIM-B) possessed maximum Hg2+ adsorption capacity of 136 mg g(-1) and 127 mg g(-1) at pH 5, respectively. Besides, the thiol-functionalized PIMs had fluorescence property and showed potential in sensing for Hg2+.

Road performance of liquid nitrile-butadiene rubber modified unsaturated polyester resin concrete

Unsaturated polyester resin concrete (UPC) is currently gaining attention in many fields due to its functional compressive capacity and corrosion resistance. However, the toughness of UPC is poor due to the weak resistance to the deformation of the cured unsaturated polyester resin (UP). In this paper, the UP was modified with liquid nitrile-butadiene rubber (LNBR) and further used to make concrete. At the same time, two different initiators were used to cure the UPC and LNBR modified UPC. To study the mechanism and road performance of LNBR modified UPC performance, optical microscopy test, Marshall test, water immersion Marshall test, rutting test, freeze-thaw split test, and infrared spectroscopy experiments were carried out. Test results showed that LNBR could effectively improve the low-temperature toughness of UPC. Although LNBR slightly reduced the Marshall stability and rutting resistance of UPC, it hardly changed the water stability of the UPC. LNBR could crosslink with UP to form a joint body, and the amount of initiator may have a more significant impact on the performance of the UPC and LNBR modified UPC. (C) 2020 Elsevier Ltd.

Nitrile Oxidation at a Ruthenium Complex leading to Intermolecular Imido Group Transfer

The oxidation of an acetonitrile ligand coordinated to ruthenium is explored in deuterated dimethyl sulfoxide by H-1 NMR spectroscopy. When oxidized with an iodosoarene oxygen atom transfer (OAT) reagent, kinetic studies demonstrate that the nitrile ligand does not dissociate before reacting. Instead, OAT to the central nitrile carbon is implicated (nitrile oxidation) and is further supported by the product of the reaction, N-acyldimethylsulfoximine. The N-acyldimethylsulfoximine likely formed by an imido group transfer reaction from ruthenium to the NMR solvent, and the product was synthesized independently to verify its identity in the reaction. This reaction represents the first time that a nitrile oxidation reaction has resulted in intermolecular imido group transfer to a substrate, presumably through a reactive ruthenium(IV)imido intermediate. This suggests that nitrile oxidation is a plausible route into reactive metal-imido intermediates for amination and aziridination reactions.

Fabrication, characterization, dielectric properties, thermal stability, flame retardancy and transport behavior of chlorinated nitrile rubber/hydroxyapatite nanocomposites

This work focused on the preparation of chlorinated nitrile rubber (Cl-NBR)/hydroxyapatite (HA) nanocomposites by an open two-roll mixing mill. The formation of nanocomposites was characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). The dielectric properties and flame retardancy of polymer nanocomposites were analyzed with special attention to the loading of HA nanoparticles. Diffusion and permeation properties of petroleum solvents through the prepared Cl-NBR/HA composites were also investigated in detail as a function of filler content, different temperatures and nature of solvent. The incorporation of HA in Cl-NBR has been endorsed by FTIR analysis. The XRD showed the crystalline peaks of HA in the polymer chain. SEM images revealed that the nanoparticles were uniformed distributed in the polymer network with spherically shaped particles. TGA results indicated that the thermal stability of nanocomposites was remarkably higher than the pure Cl-NBR and the thermal stability increases with the loading of nanoparticles. The dielectric study observed a decreasing dielectric constant with increasing frequency, and the maximum property was obtained for 7 phr HA filling in Cl-NBR. The flame resistance of the polymer composites was greatly enhanced by the incorporation of nanoparticles. The diffusion, sorption and permeation constants were found to decreased with increase in HA content. The solvent uptake decreases with the size of the penetrant molecules, and the mechanism of transport of Cl-NBR composite was anomalous in nature. The enthalpy and entropy changes of the nanocomposites were analyzed from the diffusion data. The composite containing 7 phr HA sample showed higher dielectric properties and better solvent resistance properties.
