“…70 In addition, sodium periodate may partly cleave the lignin network connectivities, as prominently observed under harsher conditions. 110,111 It can be speculated that the opening of the intramolecular network bonds leads to increased accessibility to the interior catechol entities by periodate to also improve the downstream addition of thiols to quinones.…”

“…The formation mechanism of the ortho-quinones through directly selective oxidation of the free phenolic hydroxyl groups of both guaiacyl (G) and syringyl (S) building block in lignin structure has been reported (Adler and Hernestam 1955;Chang et al 1975). Recently, industrial lignin was oxidized using sodium periodate, enabling the formation of the ortho-quinones group of lignin (Gosselink et al 2011;Kozhevnikov et al 2017;Zhang and Fatehi 2019;Chen et al 2021). Moreover, the use of either industrial lignin individually or in combination with furfuryl alcohol under periodate oxidation to produce formaldehyde-free adhesives has been investigated (Gosselink et al 2011;Chen et al 2021).…”

To eliminate toxic formaldehyde from wood-based panels, a new formaldehyde-free wood adhesive (named OL/PEI adhesive) was synthesized by a reaction of oxidized lignin (OL) and polyethylenimine (PEI) reaction in the presence of sodium periodate. The curing mechanism of the OL/PEI adhesive was clarified by Fourier transform infrared spectroscopy (FTIR) and solid-state cross-polarization magic angle spinning carbon-13 nuclear magnetic resonance (CP/MAS13C-NMR) spectroscopy. The results showed that the sodium periodate could selectively oxidize wheat straw lignin to produce the ortho-quinone, and then the ortho-quinone in OL could further react with amino groups in PEI to form the OL/PEI adhesive. The as-prepared poplar particleboard was investigated with regard to hot-pressing temperature, the hot-pressing time, the OL/PEI weight ratio, and the dosage of OL/PEI adhesive. Under the optimum conditions, e.g., hot pressing temperature of 180 °C, hot pressing time of 13 min, the OL/PEI weight ratio of 1:1, and the dosage of 10%, OL/PEI adhesive was found to disperse evenly into the voids among the shavings of poplar particleboard, followed by the curing of OL/PEI adhesive using hot-pressing to form tightly bonds between the shavings. The resulting particleboard reached the requirement of mechanical properties (GB/T 4897.3-2003), higher water resistance properties, and better heating resistivity. This study demonstrated a new way to produce a formaldehyde-free wood adhesive with unique properties. This material could replace formaldehyde wood adhesive in wood bonding.
