The goal of this paper is to analyze the chemical composition of untreated and
treated wooden chips from the native narrow-leaved ash (Fraxinus angustifolia
Vahl. ssp. Pannonica Soó & Simon). In order to determine the effect of pretreatment
with liquid hot water (LHW) on changes in chemical composition, the content
of moisture, cellulose, lignin, minerals (ash), extractives soluble in hot water, extractives
soluble in organic solvents, for treated and for untreated wooden chips
was determined. This was done in accordance with TAPPI and ASTM standard
methods. The properties of wooden chips, treated for 30 min and 60 min at a
temperature of 100 °C, are compared to untreated wooden chips and changes
in the chemical composition that occurred are defined as a result of the applied
treatments. The research was performed under controlled conditions in a laboratory,
and the results of treatments were the subject of comparative analysis. Applied
treatments had a statistically signif...icant effect on decreasing the content of
extractives. The content of cellulose and hemicellulose increased in the treated
wooden chips compared to untreated wooden chips, while the lignin content did
not significantly change.
