Recognition of 1,3‐Butadiene by a Porous Coordination Polymer

04-Oct-2016 | Keisuke Kishida, Yoshikuni Okumura, Yoshihiro Watanabe, Megumi Mukoyoshi, Silvia Bracco, Angiolina Comotti, Piero So ..., Angewandte Chemie International Edition, 2016

Abstract The separation of 1,3‐butadiene from C4 hydrocarbon mixtures is imperative for the production of synthetic rubbers, and there is a need for a more economical separation method, such as a pressure swing adsorption process. With regard to adsorbents that enable C4 gas separation, ...

From Sugars to Wheels: The Conversion of Ethanol to 1,3‐Butadiene over Metal‐Promoted Magnesia‐Silicate Catalysts

19-May-2016 | Sankaranarayanapillai Shylesh, Amit A. Gokhale, Corinne D. Scown, Daeyoup Kim, Christopher R. Ho, Alexis T. Bell, ChemSusChem, 2016

Abstract 1,3‐Butadiene (1,3‐BD) is a high‐value chemical intermediate used mainly as a monomer for the production of synthetic rubbers. The ability to source 1,3‐BD from biomass is of considerable current interest because it offers the potential to reduce the life‐cycle greenhouse gas (GHG) ...

Green metrics evaluation of isoprene production by microalgae and bacteria

31-Jul-2013 | Cristina T Matos; Luisa Gouveia; Ana Rita C. Morais; Alberto Reis; Rafal Marcin Bogel-Lukasik, Green Chemistry, 2013

Isoprene is a key intermediate compound for the production of synthetic rubber and adhesives and is also used as a building block for the chemical industry. Traditionally, isoprene is obtained from crude oil during the refinery process. Nevertheless, plants and animals are also able to synthetize ...

Fabrication and characterization of NBR/MWCNT composites by latex technology

11-Aug-2012 | Hongxia Jiang, Qingqing Ni, Hongfu Wang, Jihong Liu, Polymer Composites, 2012

Abstract To develop a rubber composite with excellent electrical properties, a sort of synthetic rubber, acrylonitrile butadiene rubber (NBR) with CN dipoles as matrix, multi‐walled carbon nanotubes (MWCNTs) as filler, was synthesized. NBR composites reinforced with 0.5, 1.5, 3, 10, and 20 ...

Silica–rubber microstructure visualised in three dimensions by focused ion beam–scanning electron microscopy

19-Jan-2012 | TUNNICLIFFE, L. B.; THOMAS, A. G.; BUSFIELD, J. J. C., Journal of Microscopy, 2012

Summary A focused ion beam–scanning electron microscope (FIB–SEM) technique for three‐dimensional reconstruction and representation of material microstructures was applied to a silica‐filled synthetic rubber for the first time. Backscattered electron imaging allowed differentiation between ...

Synthesis and structural characterization of a liquid polyisoprene bearing amidoxime end groups

15-Jun-2011 | Journal of Polymer Research, 2011

Abstract Azo-bis(isobutyroamidoxime) was synthesized and used as functionalized initiator to prepare a liquid isoprene bearing amidoxime end groups via radical polymerization. The polymer was characterized by FT-IR, Gel Permeation Chromatography and NMR. In particular, the structure of the ...
