Аннотация: The guar gum was sulfated for the first time with a deep eutectic solvent, a sulfamic acid/urea mixture at a ratio of (1:1). The optimal conditions of the process are shown to ensure the production of guar gum sulfate with a maximum sulfur content (16.1% wt.). The introduction of a sulfate group into a guar gum molecule is proved bПоказать полностьюy elemental analysis. A mathematical model of the process of sulfation of guar gum is calculated. It is shown that the resulting model has high predictive properties. The developed method is environmentally safer due to the fact that it eliminates the use of toxic solvents. © 2020 Published under licence by IOP Publishing Ltd.
