The etherification of sucrose in aqueous solutions is performed via butadiene telomerization catalysed by palladium complexes. degree substitution evaluated from a combination analytical techniques including NMR and LSIMS as well chromatographic gravimetric measurements. Degrees ranging 1 to 6 are obtained depending upon the experimental conditions, particularly temperature, butadiene/sucrose ratio nature catalyst. Thus, precursor salt use optimum amounts TPPTS ligand shown be critical parameters. solubility water modified molecules substantially modified.
