Tiivistelmä
The purpose of this paper was to provide a general view of chemical distribution in the wood and the method for isolated extractives from woods; And Finnish forests' situation were also studied, covering themes included from forest resources distribution to extraction process and its products.
A research of the isolation of extractives for Scots pine with non-polar solvents, such as hexane, toluene and diethyl ether, was described. The experiment was carried out in Saimaa University of Applied Sciences, Imatra, Finland. Chemical compounds were extracted through isolation of pine stem chip, pine stump bark and pine sawdust . Identification of the extracted compounds was carried out by gas chromatography .
The aim of the experiment was to investigate the different effect of solvents and raw materials, extraction time, extraction equipment, temperature on the extractives from pine wood. The various species of extractive were mainly resulted from different solvents and various raw materials. On the other hand, the extraction time and extraction temperature shows minor influence on extraction process.
