20.500.12556/DKUM-27299 Mild oxidation of cellulose fibers using dioxygen as ultimate oxidizing agent Two types of regenerate cellulose fibres were oxidized under mild conditions, by using N-hydroxyphthalimide as catalyst and molecular oxygen as ultimate oxidizing agent. The amounts of negatively charged groups introduced were determined by means of potentiometric titration. The degree of polymerization and molar mass of the oxidized fibres determined viscosimetrically, has been found to be almost unaffected during oxidation. viscose fibers modal fibers oxidation N-hydroxyphthalimide NHPI phthalimide-N-oxyl radical PINO true false false Angleški jezik Angleški jezik Neznano 2012-06-01 10:26:52 2012-06-01 10:26:52 2022-04-15 03:43:59 2021-04-11 03:25:00 2011 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 677.1:543 14769430 1842-3582 URN:SI:UM:DK:VBXMUZ9Y http://www.chalcogen.infim.ro/293_Biliuta.pdf 1 https://dk.um.si/Dokument.php?lang=slv&id=36572 Fakulteta za strojništvo 0 0 0
