Title (DE) VERFAHREN ZUR HERSTELLUNG VON CARBONFASERN AUS MIT SULFONSÄURESALZEN BEHANDELTEN CELLULOSEFASERN
(EN) METHOD FOR PRODUCING CARBON FIBRES FROM CELLULOSE FIBRES TREATED WITH SULPHONIC ACID SALTS
(FR) PROCÉDÉ DE PRODUCTION DE FIBRES DE CARBONE À PARTIR DE FIBRES DE CELLULOSE TRAITÉES AVEC DES SELS D'ACIDE SULFONIQUE
Abstract:
(DE) Verfahren zur Herstellung von Carbonfasern aus Cellulosefasern, dadurch gekennzeichnet, dass Cellulosefasern, welche ein Sulfonsäuresalz der Formel (I) enthalten, wobei R1 für eine Kohlenwasserstoffgruppe und K+ für ein Kation steht, in Carbonfasern überführt werden.
(EN) The invention relates to a method for producing carbon fibres from cellulose fibres, characterised in that cellulose fibres, which contain a sulfonic acid salt of formula (I), wherein R1 represents a hydrocarbon group and K+ represents a cation, are converted into carbon fibers.
(FR) Procédé de préparation de fibres de carbone à partir de fibres de cellulose, caractérisé en ce que les fibres de cellulose, qui contiennent un sel d'acide sulfonique de formule (I), dans laquelle R1 représente un groupe hydrocarboné et K+ représente un cation, sont transformées en fibres de carbone.
