“…This might be due to the different reactions in the thermal modi cation process caused by the different hemicellulose, lignin and extracts of spruce and poplar wood. For example, the mass loss after thermal modi cation and acetone extract yield of 180°C TMS (1.8% and 3.1%) were higher than those of TMP (1.2% and 2.8%), while acetone is a highly polar solvent and its extract is hydrophilic (Smeds et al 2021;Korenman et al 2010). The lower moisture absorption of TWS might be due to the removal of more acetone extracts with hydrophilic.…”

Thermal modi cation can enhance the color as well as improve the dimensional stability and decay resistance of wood without the use of chemical modi er, but the impact of extracts from thermally modi ed wood (TMW) on performance remains unclear. In order to utilize extracts to regulate the properties of the TMW or prepare the imitate TWM without mechanical loss, the effects of TMW acetone extracts on the color, dimensional stability, and decay resistance of TMW were investigated. The 180°C, 200°C and 220°C thermally modi ed spruce (Picea asperata Mast.) and poplar (Populus tomentosa Carr.)with or without acetone extract were used for CIELab system, anti-swelling e ciency(ASE), and decay resistance test. Fourier infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS) were used to characterize extracted and unextracted TMW. The results indicated that the extract showed positive effects on the color, dimensional stability (220°C), and decay resistance of TMW, and this effect weakened with the increase of temperature. The brightness difference (∆L*) and the total color difference (∆E*) of the TMW were reduced due to the removal of the extract, and the wood thermally modi ed at 180°C was the most signi cant. The removal of the extract will lead to the improvement of the dimensional stability of the TMW at 180°C and 200°C and the reduction of the TMW at 220°C. The decay resistance of wood thermally modi ed at 180°C, 200°C, and 220°C decreased after extraction, and was most signi cant at 180°C. The antifungal activity of the extract was related to the production of vanillin, isovanillic acid, syringic acid and syringaldehyde. Extract from TMW played an important role in the properties of TMW, and can be used to adjust its properties or as a natural wood modi er.

Overarching principles for salting-out extraction are long-established but poorly disseminated. We highlight the opportunity for more widespread application of this technique using the Hofmeister series as a foundational basis for choosing the right salt. The power of this approach is exemplified by the aqueous workup of a highly water-soluble nucleoside in which the use of sodium sulfate allowed for high recoveries without relying on back extraction.
