- W2373764644 abstract "2,2,6,6-Tetramethyl-1-piperidinyloxy radical(TEMPO)-NaClO-NaBr mediated oxidation of guar was studied at pH 9.30 and at temperature of 0 ℃ with NaOCl as the primary oxidant.Two phases were observed from typical kinetic plot of TEMPO-mediated oxidation of guar gum as monitored by the consumption of NaOH.From the IR spectra,the absorption bands of the C=O was observed in the 1615 cm-1 while it shifted to the 1739 cm-1 after acidifying the samples.It indicates that the absorption bands of oxidized guar gum is-COOH group.From 13C-NMR spectra the fact that the carboxylate resonate could be found at near 175 indicates that the hydroxyl of C6 is oxidized to-COOH.But no resonance in the 198~210 region was observed,indicating no ketone group formation during the oxidation.Furthermore,the degree of oxidation of guar gum increased with the increasing substitution degree of hydroxypropyl group in guar gum under this experiment condition." @default.
