  1. 1. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    University essay from Karlstads universitet

    Author : Shiniar Said Saleh; [2023]
    Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  3. 2. Oxidation of cellulose to favour its dissolution in alkaline aqueous solution before regeneration into textile yarn

    University essay from KTH/Kemiteknik

    Author : Martin Orpiszak; [2021]
    Keywords : Cellulose; periodate oxidation; dissolution; regeneration; textile yarn; cellulosa; natriumperjodat oxidation; upplösning; regenerering; textilgarn;

    Abstract : Detta examensarbete är en del av CelluFil-projektet och syftar till att optimera förhållandena för upplösning av cellulosa i vattenlösning av natriumhydroxid följd av regenering i form av ett garn. Tidigare arbeten har visa tatt cellulosa kan lösas i vattenlösning vid -10°C, men sådana förhållanden är inte tillämpliga i industriell skala. READ MORE

  4. 3. Pulp compositions and their influence on the production of dialcohol cellulose

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktoria Carlsson; [2020]
    Keywords : ;

    Abstract : The characteristics of products made from pulp can be modified through different methods. If the pulp is refined either laboratory or industrially, the fibres in the pulp become more flexible and therefore creates stronger bonds to each other, which results in a final product with a higher strength.

  5. 4. Production of Dialdehyde Cellulose and Periodate Regeneration: Towards feasible oxidation processes

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Elisabeth Höglund; [2015]
    Keywords : Dialdehyde cellulose; periodate regeneration;

    Abstract : Cellulose is an attractive raw material that has lately become more interesting thanks to its degradability and renewability and the environmental awareness of our society. With the intention to find new material properties and applications, studies on cellulose derivatization have increased. READ MORE
