Method for improved wet strength paper
Tong Sun,Jeffrey Dean Lindsay +1 more
TL;DR: In this paper, a method for improving the efficiency of aqueous cationic wet strength additives by pretreating cellulose surfaces with reactive anionic compounds, thus providing the cellulose surface with additional anionic sites suitable for retaining a high proportion of said catedic wet-strength additives on the celluloses, was proposed.
Journal ArticleDOI
Redox reactions of 3,5-di-tert-butyl-1,2-benzoquinone. Implications for reversal of paper yellowing
TL;DR: One and two-electron transfer reactions of 3,5-di-tert-butylcatechol and the corresponding quinone were studied by fast kinetic spectroscopy coupled with laser photolysis and pulse radiolysis as mentioned in this paper.
Journal ArticleDOI
Semiquantitative Determination of Quinonoid Structures in Isolated Lignins by 31P Nuclear Magnetic Resonance
TL;DR: In this article, a semiquantitative analytical method has been developed for the determination of the total quinonoid content (o-benzoquinones and p-benzosquinones) of soluble lignins.
Journal ArticleDOI
The reactions of chromophores of the stilbene type with hydroxyl radical (HO.) and superoxide radical (O2.-/HO2.). Part I. The cleavage of the conjugated double bond
TL;DR: In this article, the reactions of three methoxy-substituted stilbenes with hydroxyl radicals and superoxide radicals under alkaline and acidic conditions have been studied.
