  1. 1. New Methods for Enzyme Hydrolysis, Analysis, and Characterization of Modified Cellulose

    Author : Claes Melander; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; Methyl Cellulose; Reducing End; Micro Immobilised Enzyme Reactor; Mass Spectrometry; Enzyme Hydrolysis; Modified Cellulose; Substituent Distribution;

    Abstract : Cellulose can be chemically modified to produce derivatives with specific properties. Knowledge of correlations between the modification reaction, substituent distribution, origin of cellulose and properties are importaint in order to design processess so as to produce derivatives with the desired properties.

  2. 2. Understanding overlooked molecular interactions in the cellulose/NaOH(aq) system

    Author : Maria Gunnarsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ATR-IR; dissolution; cellulose; NMR; urea; CO2; NaOH aq ;

    Abstract : The cold NaOH(aq) system is a promising process for the production of textile fibres. Although the process has been studied for almost a century, there remain unsolved research issues, especially regarding the dissolution mechanism. READ MORE

    Abstract : This thesis is focused on applying modification chemistry to already known cellulosic substrates from wood (i.e. cellulose nanofibrils, CNFs, and cellulose nanocrystals, CNCs). READ MORE

  5. 5. Investigation of CO2 interactions with cellulose dissolved in the NaOH(aq) system

    Author : Maria Gunnarsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DBU; ATR-IR spectroscopy; NaOH aq ; dissolution; NMR spectroscopy; CO2; cellulose;

    Abstract : Cellulose derived from wood can be used as raw material for production of textile fibres, making it a renewable alternative to fossil oil. One of the key steps in this process is dissolution of the cellulose. READ MORE
