Publication number: 20160207776Abstract: In a process for purifying graphene nanoribbons, a composition comprising graphene nanoribbons GNR1 and at least one contaminant is brought into contact with a liquid medium that includes a dispersant. The graphene nanoribbons GNR1 are dispersed in the liquid medium so as to obtain a liquid dispersion of the graphene nanoribbons GNR1. The liquid dispersion of the graphene nanoribbons GNR1 is subjected to a separation treatment so as to at least partly remove the at least one contaminant, thereby obtaining a liquid dispersion of purified graphene nanoribbons GNR1.Type: ApplicationFiled: August 25, 2014Publication date: July 21, 2016Inventors: Tobias Hintermann, Matthias Georg Schwab, Kitty Chih-Pei Cha, Thomas Weitz, Ansgar Schäfer, Imke Britta Müller

Patent number: 7615645Abstract: The invention relates to a method for the continuous production of aldehydes by the isomerising hydroformylation in a homogenous phase of olefin compositions by means of a synthesis gas, in the presence of a homogeneous rhodium catalyst that is complexed with an organophosphorus ligand containing oxygen atoms and/or nitrogen atoms and a free ligand. The production is carried out at high temperature and high pressure in a multi-stage reaction system consisting of at least two reaction zones. According to the method, the olefin composition is first reacted in a first reaction zone or a group of several first reaction zones at a total pressure of between 10 and 40 bar, using a synthesis gas with a CO/H2 molar ratio of between 4:1 and 1:2 until a 40 to 95% conversion of the ?-olefins is obtained.Type: GrantFiled: October 14, 2004Date of Patent: November 10, 2009Assignee: BASF AktiengesellschaftInventors: Martin Volland, Thomas Mackewitz, Wolfgang Ahlers, Ansgar Schäfer, Wolfgang Richter, Rocco Paciello
