Abstract
Foreliggende oppfinnelse vedrører en ny masse, som er avledet fra lignocellulosemateriale utsatt for omrøring i vandig tetra-alkylammoniumsaltløsning under mikrobølgebestråling. Oppfinnelsen vedrører også en fremgangsmåte for masseoppslutting av lignocellulosemateriale og en fremgangsmåte for å mykne lignocellulosemateriale. Det behandlete materialet er fortrinnsvis trevirke, bartre eller løvtre.The present invention relates to a novel mass derived from lignocellulosic material subjected to stirring in aqueous tetra-alkylammonium salt solution under microwave irradiation. The invention also relates to a method for mass digesting lignocellulosic material and a method for softening lignocellulosic material. The treated material is preferably wood, coniferous or hardwood.
