New alkylated xanthan gum as amphiphilic derivatives: Synthesis, physicochemical and rheological studies

This research aims to develop new hydrophobically modified derivatives of xanthan gum with amphiphilic character by the grafting of octyl chains onto xanthan gum (XG) backbone using a Williamson synthesis. The etherification reaction between 1-Octyl chloride and the hydroxyl groups of XG at a reagent/monomer ratio (R = 1) was carried out in two different reaction media: Ethanol and Dimethylsulfoxyde (DMSO). The two derivatives HMXG1 and HMXG2,...
