Fourier transform and near infrared dataset of dialdehyde celluloses used to determine the degree of oxidation with chemometric analysis

Abstract

This dataset is related to the research article entitled ``A fast method to measure the degree of oxidation of dialdehyde celluloses using multivariate calibration and infrared spectroscopy''. In this article, 74 dialdehyde cellulose samples with different degrees of oxidation were prepared by periodate oxidation and analysed by Fourier-transform infrared (FTIR) and near-infrared spectroscopy (NIR). The corresponding degrees of oxidation were determined indirectly by periodate consumption using UV spectroscopy at 222 nm and by the quantitative reaction with hydroxylamine hydrochloride followed by potentiometric titration. Partial least squares regression (PLSR) was used to correlate the infrared data with the corresponding degree of oxidation (DO). The developed NIR/PLSR and FTIR/PLSR models can easily be implemented in other laboratories to quickly and reliably predict the degree of oxidation of dialdehyde celluloses.

Delivery of soluble ethinylestradiol complex by pH‐responsive core‐shell composite hydrogel capsules

“…Based on previous studies, 47–50 we determined the degree of aldehyde substitution of AC using the hydroxylamine hydrochloride method. According to Equations and , the aldehyde group can be reacted with hydroxylamine hydrochloride to form HCl, and the HCl produced by the reaction can be titrated by NaOH solution to obtain the content of the aldehyde group on AC. …”

Reductive Amination of Dialdehyde Cellulose: Access to Renewable Thermoplastics

“…The DO of DAC from softwood kraft pulp was determined from the FTIR spectrum combined with partial least squares regression according to our previous work. , The published model was used to predict the DO from the recorded FTIR spectrum. The DO of DAC from microcrystalline cellulose was determined by potentiometric titration after treatment with hydroxylamine hydrochloride.…”

Feasibility study of oxidized naringin as a novel crosslinking agent for crosslinking decellularized porcine Achilles tendon and its potential application for anterior cruciate ligament repair

“…The number of aldehyde groups in ONar could be determined by hydroxylamine hydrochloride potentiometric titration 32 . ONar weighing 0.1 g was dissolved in 25 ml hydroxylamine hydrochloride‐methyl orange solution (0.25 mol/L), and the mixed solution was placed in a shaker for 2 h. The hydrochloric acid produced in the mixture was titrated with 0.1 mol/L NaOH standard solution.…”

“…The number of aldehyde groups in ONar could be determined by hydroxylamine hydrochloride potentiometric titration. 32 ONar weighing 0.1 g was dissolved in 25 ml hydroxylamine hydrochloride-methyl orange solution (0.25 mol/L), and the mixed solution was placed in a shaker for 2 h. The hydrochloric acid produced in the mixture was titrated with 0.1 mol/L NaOH standard solution. The titration was discontinued when the color of the solution changed from red to yellow, and the number of aldehyde groups were obtained through the consumed volume of sodium hydroxide.…”
