Reducing boron leaching from impregnated wood has been one of the most challenging tasks for at least 50 years. In order to slow down the leaching of boron, aqueous solutions of boric acid were combined with liquefied spruce wood. The results clearly showed that leaching of boron from spruce wood impregnated with preservative solutions based on boric acid and liquefied wood was significantly reduced.

We optimized liquefaction of celulignine, spruce wood, cellulose and straw in glycerol with a catalyst sulfuric acid. During biomass liquefaction reactions volatile products were formed and analyzed with gas chromatograph coupled to a mass spectrometer (GC-MS). We found out that all type of biomass could be liquefied in glycerol reaction reagent. In volatile products we identified furfural, which could be used as industrial chemical intermediate. With this discovery we open a new way for more effective uses of liquefaction products.
