Abstract [en]

Recently, it has been demonstrated that triethyloctylammonium chloride (N2228Cl) bears great properties as cellulose solvent both as melt and in combination with organic solvents (Kostag et al. 2013; Kostag et al. 2014). On one hand, N2228Cl and N,N-dimethylacetamide (DMAc) dissolve cellulose within 2 h without prior activation of the polysaccharide. On the other, N2228Cl unexpectedly dissolves cellulose in the presence of acetone, which typically is known as precipitation agent for cellulose. On very recent studies, the novel solvent was applied for tosylation, acetylation and silylation of cellulose (Achtel 2016). These types of reactions were chosen, because tosylcellulose is an important intermediate for nucleophilic displacement reaction with cellulose, cellulose acetates are of industrial interest, and silylation of cellulose is commonly used to achieve products that form ultrathin films by spin-coating useful as model surface. The reactions were studied under different conditions and the resulted degree of substitutions (DS) were compared with values obtained in common cellulose solvents (LiCl/DMAc, DMSO/TBAF or ionic liquids).
