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).
